Answer:

x = 1 y = 3

Step-by-step explanation:

6x - 3 + 3 = 4x - 1 + 3

6x - 4x = 4x - 4x + 2

2x = 2 ÷ 2

x = 1

y = 6x - 3

y = 6 (1) - 3

y = 6 - 3

y = 3

Answer:

7 and 1

Step-by-step explanation:

To evaluate f(- 5) substitute x = - 5 into f(x)

f(- 5) = - (- 5) + 2 = 5 + 2 = 7

Similarly for f(1)

f(1) = - 1 + 2 = 1

Answer:

x < 9  

Step-by-step explanation:

Writing this entirely with symbols, we get:

-5(x - 1) > -40

We must solve for x.  

Carrying out the multiplication, we get:

-5x + 5 > -40, or

-5x > -45

Dividing both sides by -5 isolates x:

x < 9  

Note that when working with an inequality such as this one, dividing both sides by a negative number requires changing the direction of the inequality symbol.

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cut-off point with the y axis

By definition, if two lines are parallel then their slopes are equal. A line parallel to[tex]y = -3x + 1[/tex], will have the same slope -3. Thus, the equation will be of the form:

[tex]y = -3x + b[/tex]

We substitute the given point and find "b":

[tex]2=-3(4)+b\\2=-12+b\\2+12=b\\b=14[/tex]

Finally, the equation is:

[tex]y = -3x + 14[/tex]

Answer:

[tex]y = -3x + 14[/tex]

Step-by-step explanation:

Answer:

x>26

Step-by-step explanation:

Subtract 47 from 21.

Now that you have 26, that is the least amount needed because in the question it says "at least". (The inequality sign is suppose to be greater than or equal to)

Answer:
The answer is x>26

Step-by-step explanation:

to graph this inequality you would have to put an open circle on 26 and go right.

Answer:

63 ft²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (a + b)

where a and b are the parallel bases and h the perpendicular height

Here a = 7, b = 14 and h = 6, thus

A = [tex]\frac{1}{2}[/tex] × 6 × (7 + 14) = 3 × 21 = 63 ft²

Slope-intercept form:  y = mx + b

[m is the slope, b is the y-intercept or the y value when x = 0 ---> (0, y) or the point where the line crosses through the y-axis]

For lines to be perpendicular, their slopes have to be negative reciprocals of each other. [basically changing the sign (+/-) and flipping the fraction/or switching the numerator and the denominator]

For example:

m = 2 or [tex]\frac{2}{1}[/tex]

Perpendicular line's slope = [tex]-\frac{1}{2}[/tex]

m = [tex]-\frac{1}{4}[/tex]

Perpendicular line's slope = [tex]\frac{4}{1}[/tex] or 4

Since you know the slope of the line is:

y = -3/4x + 5

m = [tex]-\frac{3}{4}[/tex]      

The perpendicular line's slope is [tex]\frac{4}{3}[/tex], so plug it into the equation

y = mx + b

[tex]y=\frac{4}{3} x+b[/tex]        To find b, plug in the point (-3, -3) into the equation

[tex]-3=\frac{4}{3} (-3)+b[/tex]

-3 = -4 + b   Add 4 on both sides to get "b" by itself

1 = b

The y-intercept is 1

Answer:3

Step-by-step explanation:

3 ^x= 27

X=3

Answer: $30

Step-by-step explanation:

The lamp was selling for $30 which is 25% less than what Cindy bought.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, Cindy bought a new lamp for $40.00.

She later saw the lamp on sale for 25% less than what she had originally paid.

∴ The discounted price of the lamp is 75% of the price for which Cindy bought which is,

= (75/100)×40.

= $30.00

#SPJ2

Answer: It’s A

Step-by-step explanation:

If you reflect over the y axis your point changes

m=rise/run. so it is also going to the right so it is going to be positive do the rise is one and the run is two. That way m=1/2.

To find the sum, add the numbers together. To find the difference, subtract the smaller numbers from the larger numbers.

To find the sum of 147, 167, 204, and 107, simply add the numbers together:

147 + 167 + 204 + 107 = 625

To find the difference, subtract the smaller numbers from the larger numbers:

204 - 147 = 57

167 - 107 = 60

Therefore, the sum is 625 and the differences are 57 and 60.

Answer:

7 gallons of gas

Step-by-step explanation:

because the car can drive 53 miles on 1 gallon and your trying to find the amount of gallons needed for 371 miles you would divide 371 by 53 and you get 7.

Final answer:

To find out how many gallons of gas are used to drive 371 miles in a hybrid car with a fuel economy of 53 miles per gallon, divide 371 by 53, resulting in 7 gallons of gas needed.

Explanation:

To determine how many gallons of gas a hybrid car will use to drive a total of 371 city miles when the car can drive 53 miles on 1 gallon of gas, you can set up a simple division problem. The formula to calculate gallons used is:

Total miles driven ÷ Miles per gallon = Gallons of gas used

In this case, we divide 371 miles by 53 miles per gallon to find the total gallons of gas used:

371 miles ÷ 53 miles/gallon = 7 gallons

So, the hybrid car will use 7 gallons of gas to drive 371 city miles.

Answer:

301.44 feet.

Step-by-step explanation:

Given: Distance between the girl and the center of the carousel is 8 feet.

            Girl stands in a carousel and rotates around the ride 6 times.

We know the radius if carousel is 8 feet.

Now, finding the circumference of carousel to find the area covered in one rotation of carousel.

Circumference= [tex]2\pi r[/tex]

⇒ Circumference= [tex]2\pi \times 8[/tex]

∴ Circumference= [tex]16\pi[/tex]

As given, carousel rotated 6 times.

Length covered in 6 rotation of carousel= [tex]6\times 16\pi[/tex]

⇒ Length covered in 6 rotation of carousel= [tex]96\pi[/tex]

Taking, π = 3.14

⇒ Length covered in 6 rotation of carousel= [tex]96\times 3.14[/tex]

∴Length covered in 6 rotation of carousel= [tex]301.44\ feet[/tex]

Hence, 301.44 feet travelled by little girl in a Carousel.

The little girl traveled approximately 301.62 feet.

To find the distance the little girl traveled on the carousel, we need to calculate the circumference of the circle and then multiply by the number of rotations.

The formula for the circumference of a circle is:

C = 2 × π × r

where r is the radius. Here, the radius r is 8 feet.

C = 2 × π × 8

C = 16π

So, the circumference is approximately 50.27 feet (since π ≈ 3.14).

Since the girl rotates around the carousel 6 times:

Total Distance = Number of Rotations × Circumference

Total Distance = 6 × 50.27

Total Distance ≈ 301.62 feet

Therefore, the little girl traveled approximately 301.62 feet.

Answer: 36 degrees

Step-by-step explanation:

The angle a is 63 degrees because 177 and a are supplementary and equal 180 degrees. Because there are 180 degrees in a triangle, 63+ 81 is 144. 36 and 144 is 180, therefore b is equal to 36.

Hope this helped!

An exterior angle of a triangle equals the sum of its opposite interiors.

The measure of b is 36 degrees

To calculate angle b, we use the following equation

[tex]b + 81 = 117[/tex] ------- because b and 81 are opposite interior angles to 117

Solving further, we have:

[tex]b = 117 - 81[/tex]

Evaluate like terms

[tex]b = 36^o[/tex]

Hence, the measure of b is 36 degrees

Step-by-step explanation:

We have,

[tex](x^{\dfrac{1}{8}})(x^{\dfrac{3}{8}})=12[/tex]

To find, the possible value of x = ?

∴ [tex](x^{\dfrac{1}{8}})(x^{\dfrac{3}{8}})=12[/tex]

⇒ [tex]x^{\dfrac{1}{8}+\dfrac{3}{8}}=12[/tex]

Using the exponential identity,

[tex]a^{m} a^{n} =a^{m+n}[/tex]

⇒ [tex]x^{\dfrac{1+3}{8}}=12[/tex]

⇒ [tex]x^{\dfrac{4}{8}}=12[/tex]

⇒ [tex]x^{\dfrac{1}{2}}=12[/tex]

Squaring both sides, we get

[tex](x^{\dfrac{1}{2}})^2=(12)^2[/tex]

⇒ [tex]x^{{\dfrac{1}{2}}\times2}=144[/tex]

⇒ x = 144

∴ The possible value of x = 144
