Answer:
Option A 
Step-by-step explanation:
we have

we know that
f(-3) is the value of f(x) when the value of x is equal to -3
so
For x=-3
substitute the value of x=-3 in the equation



The price of car is $18000
Step-by-step explanation:
Given
Sales tax on car = $1080
Rate = 6%
Let x be the price of the car
We know that as the rate of sale tax is 6%, 6% of x is 1080
Using mathematical notation
0.06x = 1080
Dividing both sides by 0.06

Hence,
The price of car is $18000

8y-3=6y+17
add 3 on both sides
8y=6y+20
-6y on both sides
2y=20
divide by 2 on both sides
y=10
Answer:
y = 4x + 8
Step-by-step explanation:
A linear formula always follows by y = mx + c, where m is the gradient and c is the y-intercept or constant.
Since you know that the slope is 4, all you need to do is find the y-intercept (constant)
y = 4x + c
Sub in the points (-4, -8)
-8 = 4(-4) + c
-8 + 16 = c
c = 8
Hence, y = 4x + 8
