Solving systems of equations algebraically.
y = x + 2
y= -3
And SHOW YOUR WORK PLEASE!!!!
Answer:
x = -5
y = -3
Step-by-step explanation:
Since it already gives you the value of y, all you need to do to solve for x, is to plug in the number into the equation, like so:
y = x + 2
-3 = x + 2
Now, subtract 2 from both sides:
-3 = x + 2
-2 - 2
________
-5 = x
So now you have, x = -5 and y = -3
So you first set them equal to each other I pretty sure...
x+2=-3
Then you solve so...
x+2=-3 (bring the two over)
x=-3-2 (you add and keep the negative sign)
x=-5

Probabilities of compound
events
If you roll two fair six-sided dice, what is the
probability that both dice show an odd number?
Stuck? Watch a video or use a hint.
Rolling two dice is an example of independent events. It means that knowing the result of one die does not influence what you expect from the other.
When this is the case, the probability of the compound event is the product of the two probabilities.
Each die shows an odd number with probability 3/6=1/2, because there are three odd numbers (1, 3 and 5) out of the six possible numbers the die will show (1, 2, 3, 4, 5, 6).
So, if you multiply the probabilities of each die showing an odd number, you'll get the probability of the compound event.

Sam’s business manufactures 5 times as many widgets as Mary does every hour but Sam needs to stop for a few minutes every hour and Mary does not. Mary makes 3 widgets during this time. Using the variables S for Sam and M for Mary, which equation represents this information? A) S=5M-3 B) M=S+8 C) M=5S-3 D) S= M+8
Final answer:
The equation representing the widget production relationship between Sam (S) and Mary (M) is S = 5M - 3, where Sam makes 5 times the widgets as Mary, but needs to stop for a few minutes during which Mary makes 3 widgets.
Explanation:
The question is asking us to create an equation that represents the relationship between Sam's and Mary's widget production per hour.
Since Sam manufactures 5 times as many widgets as Mary does, we know that Sam's production, S, is equal to 5 times Mary's production, M.
However, Sam needs to stop for a few minutes every hour during which time Mary makes 3 widgets.
This means we need to subtract those 3 widgets from Sam's total production to represent the time he is not working.
Therefore, the correct equation that represents this relationship is: S = 5M - 3.
This is because for every hour, Sam's production is 5 times Mary's, minus the 3 widgets Mary produces while Sam is taking a break.
Is the following situation represented by a positive integer, a negative integer, or zero? Sami was sick last week and lost 2 pounds.

A city manager made a scatter plot of number of retail stores in a certain cirty over years. The scatterplot had a trend like with an equation of y=11x+12, where y is the total number of retail stores and X is the number of years since 1990. Mark and his family moved to a city in 1997. How many retail stores were their in 1997
Answer: There were 89 retail stores in 1997.
Step-by-step explanation:
Hi, to answer this question, first, we have to calculate the number of years since 1990(x).
1997-1990 = 7 years
Now, we simply substitute x=7 (years) in the equation given
y=11x+12
y=11(7)+12
y=77+12
y = 89 retail stores
There were 89 retail stores in 1997.

Segments AB, EF, and CD intersect at point C, and angle ACD is a right angle. Find the value of g. Please help me
Answer:
37 degree
Step-by-step explanation:
AB = 180 it is a straight line
ACD = 90 degree
DE+ DCB are complimentary angles they add up to 90 they dont need to be next to each other.
DE = 53 deg
DCB = 90-53= 37 degree
g = 37 and F is its vertical angle as they share the same corner point and lay opposite each other and each have same angle 37 degree.
Without additional information, such as a diagram or specific measurements, we can't solve the presented problem. The problem seems to involve Properties of Intersection and possibly Trigonometry. Further details or a specific diagram are needed for an accurate solution.
Explanation:I'm sorry, but without additional information, such as a diagram, specific measurements, or the relationship involving variable 'g', we cannot solve the problem you've presented. Segments AB, EF, and CD intersecting at point C and angle ACD being a right angle, doesn't indicate how or where 'g' is related to these elements within your problem.
The principle that you seem to be dealing with is the Properties of Intersection and possibly the concepts of Trigonometry.
Should 'g' be an angle, trigonometry might be used to find its value. If 'g' is a segment, then concepts of intersection, parallel lines, or angle properties might solve it. Nevertheless, please provide further details or a precise diagram for an accurate solution.

Noah and Andre are 15 miles apart on a bike path when they start biking towards each other. Noah rides at a constant speed of 4 miles per hour, and Andre rides at a constant speed of 2 miles per hour. How long does it take until Noah and Andre meet?
Choose one of these answers
2 hours
2 1/2 hours
1 3/4 hours
3 hours
Answer:
2 1/2 hours
Step-by-step explanation:
multiply their rate by the number of hours
4*2=8
2*2=4
We want them to both equal 15 when added together
8+4≠15
So it's not 2 hours
So now our next answer choice is 2 1/2 hours
Ok that's easy, we can still use what we did from the last answer choice (2 hours)
Since it says 1/2 that means we can multiply the rate by 0.5 or divide it by 2
4/2=2
2/2=1
2+1=3
Now we add that to 8+4
8+4=12
2+1=3
12+3 = 15
Now that we've gotten 15 we know the rest of the answers are incorrect.

Answer:
Use 3.14 for p and do not round your answer. The circumference of a circular garden is 128.74 feet. What is the diameter of the garden? Use 3.14
Radius (r) = 15 feet
What is circumference of circle?Circumference of the circle or perimeter of the circle is the measurement of the boundary of the circle. If we open a circle and make a straight line out of it, then its length is the circumference. It is usually measured in units, such as cm or unit m.
When we use the formula to calculate the circumference of the circle, then the radius of the circle is taken into account. Hence, we need to know the value of the radius or the diameter to evaluate the perimeter of the circle.
Circumference of a Circle Formula:
The Circumference (or) perimeter of circle = 2πr
where,
r is the radius of the circle
π is the mathematical constant with an approximate (up to two decimal points) value of 3.14.
Given,
Circumference of the circular garden:
C = 94.2 feet
Radius (r) =?
Circumference (C) = 2πr
94.2 = 2×3.14 × r
r = 94.2/6.28
r = 15 feet
