Answer:
The function would be
.This is in the general form
, where a is the initial value, b is the rate it increases by, and x is the amount of time. For our function, the initial value is 4 and the rate it increases by is 2.
Step-by-step explanation:
Answer:
c = 10h
Step-by-step explanation:
c = 8h
Where,
c = Total amount she should charge a customer
h = Number of hours
8 = amount charged per hour of babysitting
A. 8 is the constant of proportionality and it means Nila charges $8 per hour of babysitting
B. If she decides to increase the rate she charges customers by $2 per hour, then the new equation she should use to determine how much to charge her customers is:
c = (8 + 2)h
c = 10h
Answer:
A. y=-2x+5
Step-by-step explanation:
y=mx+b , m represents slope (-2), b represents y intercept (5)
Answer:
3
Step-by-step explanation:
Given the points:
(x, y) ==> (-2, 4)
slope, m = 3
To write the slope intercept form, use the form below:
y = mx + b
Where m = slope and b = y-intercept.
Now, substitute -2 for x, 4 for y, and m for 3 in the equation above to solve for b.
We have:
y = mx + b
4 = 3(-2) + b
4 = -6 + b
Add 6 to both sides:
4 + 6 = -6 + 6 + b
10 = b
b = 10
Therefore, the slope intercept form of the equation is:
y = 3x + 10
ANSWER:
y = 3x + 10
