A triangle with side lengths of 11, 13, and 15 is a scalene triangle. True False

Answer : The expression to represent the length of each side of the rug is, [tex]Side=10x+3[/tex]

Step-by-step explanation :

As we know that the formula of area of square is:

Area of square = (Side)²

Given:

Area of square = [tex]100x^2+60x+9[/tex]

As,

Area of square = (Side)²

So,

[tex]100x^2+60x+9=(Side)^2[/tex]

[tex]\sqrt{100x^2+60x+9}=Side[/tex]

[tex]\sqrt{100x^2+30x+30x+9}=Side[/tex]

[tex]\sqrt{10x(10x+3)+3(10x+3)}=Side[/tex]

[tex]\sqrt{(10x+3)(10x+3)}=Side[/tex]

[tex]\sqrt{(10x+3)^2}=Side[/tex]

[tex](10x+3)=Side[/tex]

or,

[tex]Side=10x+3[/tex]

Thus, the expression to represent the length of each side of the rug is, [tex]Side=10x+3[/tex]

Answer: Infinitely many solutions

The second equation is equivalent to y = 2x - 5 when we subtract 5 from both sides, but this is the exact same as the first equation given to us. So we effectively have 2 copies of the same thing. One is just written in a different format.

Graphing these equations leads to the straight line. One line will be right on top of the other one. The two lines intersect an infinite number of times leading to infinitely many solutions. Any solution point is simply a point on the line y = 2x-5. The solution ordered pair is of the form (x,y) = (x, 2x-5). Two example points on this line are (0,-5) and (1,-3)

side note: We can say that this system is consistent (because it has at least one solution) and it's also dependent (because one equation depends on the other; or it is basically a copy)

The x-intercept of the equation y = -2.65x + 25 is approximately 9.43. The x-intercept generally represents the value of x at which y is zero or the point where correlation between x and y starts.

The x-intercept of a graph is the point at which the line crosses the x-axis. In terms of your equation y = -2.65x + 25, the x-intercept is found when y equals 0. By setting y equal to 0 and solving for x, we get: 0 = -2.65x + 25. Isolate x by dividing both sides by -2.65 and adding 25. This calculates to x ≈ 9.43. In terms of real life situations, the x-intercept often represents the value of x where y is nil or where the correlation between x and y begins. However, the real-world interpretation of this value depends on the context of the problem.

Answer: Choice C) line L is parallel to line M by the converse of the same side interior angle theorem

The same side interior angle theorem says that if two lines are parallel (such as L and M) then the same side interior angles that form are supplementary, meaning they add to 180 degrees.

Flip this in reverse, and you'll get the converse which says that if the same side interior angles add to 180, then the lines must be parallel.

Answer:

$5

Step-by-step explanation:

So we know that altogether Michael paid $12 right?

So if his brother's price is x  then his price is x+2

so 2x+2=12 x=5

Michael's brother's price was $5

and his was $7

In this mathematics problem, Michael's brother's movie ticket cost $10, arrived at by subtracting $2 from the total cost of $12.

This is a simple subtraction problem. According to the problem, Michael paid $12 total, with his brother's ticket costing $2 less. Therefore, if we subtract $2 from Michael's ticket, we will have the cost of his brother's ticket.

Here are the steps:

Therefore, his brother's ticket cost $10.

The tree started at 8 feet tall then grows a given amount per year.

You need to multiply the growth per year by the number of years and add it to the beginning height:

So for the Sycamore tree it would be 8 + 2.5x, so for 5 years it would be 8 +2.5(5) = 8 + 12.5 = 20.5

You do not show the possible answers, but you should be able to use the above example to figure it out.

Answer:

80 spaces

Step-by-step explanation:

You will have the points: (0,0) and (1,10) and (2,20) and (3,30) etc etc

Plot at least 2 of these points. Then draw a line through them.

Each point has an x,y pair such that the y value is ten times the x value

For example, if x = 2, then

y = 10*x = 10*2 = 20

so that shows how (2,20) is one of the points.

The domain would be the set of positive whole numbers assuming Tyler can only work a whole number of hours. If partial time values are accepted, then the domain would be the set of positive real numbers. Negative x values are not allowed as Tyler can't work negative 3 hours for instance.

In a similar fashion, the range is the set {0, 10, 20, 30, 40, ...} incrementing by multiples of 10 if x is the set of positive whole numbers. If x is the set of positive real numbers, then y can be 0 or larger which sets up the range of y being the set of positive real numbers as well.

Answer:

Step-by-step explanation:

Remark

1 solution

Rule: the number of solutions to an equation is at most the same number as the highest number on the variable. for example

x^3 + 4x^2 - 6x - 15 has at most 3 real solutions because the highest power is x^3

x^n + x^(n - 1) .... has at most n real solutions. It can have fewer.

Solution

So 6 - 3x= 12 - 6x                       Subtract 6 from both sides

6 - 6 - 3x = 12 - 6 - 6x                 Combine

-3x = 6 - 6x                                 Add 6x to both sides

-3x + 6x = 6                                Combine

3x = 6                                         Divide by 3

x = 6/3 = 2

Check

6 - 3(2) = 12 - 6(2)

0 = 0 which checks

The equation 6 —3x = 12 — 6x has one solution, which is x=2.

The equation provided, 6 - 3x = 12 - 6x, necessitates an examination of its solutions. By following algebraic procedures, it can be simplified to 6 = 12 - 3x. Further steps, such as subtracting 12 from both sides, lead to -6 = -3x. Dividing both sides by -3 results in x = 2. This mathematical process reveals a unique solution: x = 2. Consequently, the original equation confirms that there is only one valid value for x, emphasizing the equation's ultimate simplicity with a single solution.

communicative property of multiplication   is  (EX) (2)(a) = (a)(2)

Final answer:

The equation 6+4=4+6 is an example of the commutative property of addition, stating that the order of addition does not affect the sum.

Explanation:

The equation 6+4=4+6 illustrates the commutative property of addition, which states that the order in which two numbers are added does not affect the sum. This is expressed mathematically as A+B=B+A. For ordinary numbers, if you add 2 + 3 or 3 + 2, for example, both expressions will equal to the same result - 5. The commutative property is also applicable to the addition of vectors, where the order of vectors being added together does not change the resultant vector.

Answer:

C.  -5x − 3y = 0

Step-by-step explanation:

A(-3, 0) and B(-6, 5)

First we find the slope of line AB

[tex]slope = \frac{y_2-y_1}{x_2-x_1} =\frac{5-0}{-6+3} =\frac{-5}{3}[/tex]

Slope of the line parallel to AB =  slope of line AB

When the lines are parallel then their slope are equal

So the slope of line parallel to AB = [tex]\frac{-5}{3}[/tex]

The line passes through the origin (0,0)

Use equation y-y1= m (x-x1)

m = -5/3 , x1=0 and y1=0

[tex]y-0 = \frac{-5}{3}(x-0)[/tex]

[tex]y= \frac{-5}{3}(x)[/tex]

multiply the whole equation by 3

3y = -5x

Subtract 3x from both sides

0=-5x-3y

-5x - 3y =0

Use the rise over run method.

2 is the same as 2/1. So, you rise 2 square up from the origin and then go over one, repeating the process. To do it in the negative zone, you just work backwards. Down two and left one.

You should have a diagonal line going from left to right that goes through the origin. Linear equations never end. They continue on forever, so your domain would be (-infinity, infinity) and your range would be (-infinity, infinity). Be sure to use the symbol for infinity instead of the word. The symbol, in case you do not know, looks like an 8 rotated 90 degrees.

Answer: Hello mate!

You have one $20 bill, two $10 bills, three $5 bills and four $1 bills in a bag.

This adds to a total of 10 bills in the bag, and you want to know the expected value if you took one at random.

The expected value is defined as ∑pₙxₙ

where pₙ is the probability for each event (in this case is the number of bills of a given price divided the number of bills in the bag) and xₙ is the value of the bill.

Then we can write the expected value as:

E = (1/10)*$20 + (2/10)*$10 + (3/10)*$5 + (4/10)*$1 = (1/10)( 20$ + 2*$10 + 3*$5 + 4*$1) = (1/10)*($59) = $5.90

The expected value is $5.90.

The expected value of the amount chosen from a bag containing a $20 bill, two $10 bills, three $5 bills, and four $1 bills is $5.9.

In order to find the expected value of the amount chosen from the bag of bills, we need to first calculate the total monetary value of all the bills in the bag and divide it by the total number of bills. The total value is calculated as follows:

Adding up these amounts, we get a grand total of $20 + $20 + $15 + $4 = $59. Since there are 1+2+3+4 = 10 bills in the bag, the expected value is found by dividing the total value by the total count of bills: $59 / 10 = $5.9. Thus, if a bill is chosen at random from the bag, the expected value of the amount chosen is $5.9.

Answer:

y = 7/5 x + 31

Step-by-step explanation:

To find the slope, we need to use the formula

m = (y2-y1)/(x2-x1)

m =(-4-17)/(5- -10)

   = -21/(5+10)

  = 21/15

Divide the top and bottom by 3.

  = 7/5

The slope is 7/5.

Using the point slope form of the equation,

y-y1 = m(x-x1)

y-17 = 7/5 (x--10)

y-17 = 7/5(x+10)

Distribute the 7/5 ths.

y-17 = 7/5 x + 7/5*10

y-17 = 7/5 x +14

Add 17 to each side

y = 7/5 x + 14 + 17

y = 7/5 x + 31

This is in slope intercept form, with the slope  being 7/5 and the y intercept of 31

Answer:

9 is the correct answer.

Step-by-step explanation:

The general form of the determinant of the given system

ax + by = e

cx + dy = f

is [tex]\begin{vmatrix}a & b\\ c & d\end{vmatrix}[/tex]

Now, we have the given system, i.e.

2x - y = 5

x + 3y = 7

The y-determinant of a system is formed by taking the constant terms and placing them in the y‐coefficient positions in the general determinant form and keeping the x-coefficients same.

So, we get,

[tex]\begin{vmatrix}2 & 5\\ 1 & 7\end{vmatrix}[/tex]

Solve the above determinant i.e. 2*7 - 1*5 = 14 - 5 = 9

Hence, the value of y-determinant is 9.
