Answer: Substitute in the x value to see if both of the y values of both of the equations match the one you approximated from the graph.
Step-by-step explanation:
I guess that we are working with systems of equations like:
y = f(x)
y = g(x)
Where an intersection is a solution that works for both equations, which means that the graphs will intersect each other in that point.
This means that for a given value x = x0, we must have:
f(x0) = g(x0).
Now, when you find a point that you think that is an intersection, you should substitute the x value in both functions, and see if the y-values coincide.
This will be equivalent to look if f(x) = g(x) for that particular value.
then the correct option is:
substitute in the x value to see if both of the y values of both of the equations match the one you approximated from the graph.
Which transformation maps B (2,5) to B'(-2,-5)?
A. A 90 degree rotation
B. Reflection about the y-axis
C. A 270 degree rotation
D. A 180 degree rotation
Answer: B
Step-by-step explanation: Because the positive numbers changed to negatives meaning that it flipped over an axis and since both of them changed it would be the y-axis

Elise is buying a new car selling for $21,450. The rate of depreciation on this type of car is 8% per year. What is the value of the car in five years? Show your work.
Answer:
$14,137.3
Step-by-step explanation:
21450*0.92^5
so put the og value, then the value its gonna have but in decimal form - so 92% would be 0.92 and make the amount of years the square
solve
$14,137.3
The value of the car after five years will be $14135.5.
What is Compound interest?Compound interest is defined as interest paid on the original principal and the interest earn on interest of principal.
What is percentage?The percentage is defined as the ratio expressed as a fraction of 100.
The percentage is denoted by sign of %.
For example, if XYZ scored 46% marks in his test, it means that he scored 46 marks out of 100. It is written as 46/100 in the fraction form and 46:100 in terms of ratio.
The initial value of car (P) = $21,450
The rate of depreciation of car is 8% per year.
Time period (n) = 5 years
The value of the car after five years
A = P ( 1 - r/100 )ⁿ
Substitute the values of P, r and n in formula
A = 21450 ( 1 - 8/100 )⁵
A = 21450 ( 1 - 0.08 )⁵
A = 21450 ( 0.92 )⁵
A = 21450 ( 0.659 )
A = 14135.5
Hence, the value of the car after five years will be $14135.5.

What are the slope and y-intercept of the line 4y = -x - 32? PLEASE HELP
Answer: slope -1/4 y intercept -8
Step-by-step explanation:
In the form y = mx+b, m is the slope and b is the y-intercept. So let’s get it into this form, by getting y by itself.
4y = -x - 32
divide by 4 on every term
y = -1/4x - 8
therefore the slope is -1/4 and y intercept is -8

As the number of trials increase in experimental probability, the experimental probability will get farther away from the theoretical probability.
True
False
Explanation:
The more trials you do, the closer the experimental probability will get to the theoretical probability.
For example, if you flip a coin 1000 times, then you'll probably get around 500 heads or so. Maybe you could get 475 heads and 525 tails. This leads to an experimental probability of 475/100 = 0.475 of getting heads. If you flip a coin 10,000 times, then you are likely to have the experimental probability of getting heads move closer to 0.500

Which unit rate is equivalent to 19 miles per gallon?
A. three gallons over fifty seven miles
B. fifty seven miles over three gallons
C. thirty seven miles over four gallons
D. four gallons over thirty seven miles
Answer:
B
Step-by-step explanation:
57 over three means
[tex]\frac{57}{3}[/tex]
It is the same as asking how many times does 3 go into 57, or how many miles is their per one gallon.
57 divided by 3 equals 19, so B would be the correct answer.

A theater has group prices for tickets. The first ticket will cost $10 while each additional ticket costs $8. Which rule models the situation?
a. an= 10 + 8 (n - 1)
b. an-1= 10 + 8 (n - 1)
c. an= 18 (n - 1)
d. an-1= 18 (n - 1)
Answer: Choice A.
an = 10 + 8(n - 1)
=================================================
Explanation:
a1 = 10 is the first term
The common difference is d = 8 since we add 8 to each previous price to get the next price.
We have the arithmetic sequence with nth term of
an = a1 + d*(n-1)
an = 10 + 8(n - 1)
If you wanted, you could simplify that to get
an = 10 + 8n - 8
an = 8n + 2
