Let’s estimate the students to 20 and the dollars to 25 so you would multiply 20 by 25 which equals 500 so $500 would be your answer
Answer:
2
−
9
x
Step-by-step explanation:
If we look at where it is now, we would have multiplied the x and y values by 1/2. since we are working backwards, lets multiply by 2 instead...giving us the vertex for the pre-image....
J is now (0, -2) multiply by 2
J was (0, -4)
Answer:
It is 7
Step-by-step explanation:
y = mx+b
y is the total cost.
x is the number of hours.
b : that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hours
Answer:
A.
Step-by-step explanation:
Given: limit of f(x) exists at x = a
To choose: the correct option
Solution:
A limit is a value that a function approaches as the input approaches some value.
means that as x approaches to value a then f(x) approaches to value L.
A limit of a function f(x) exists at x = a if 
So, option A. is correct.
