Answer:
f(-3) =16
Step-by-step explanation:
f(x) = -5x + 1
f(-3) means let x=-3
Substituting x=-3 into the equation
f(-3) = -5 (-3) +1
Multiplying -5 and -3
f(-3) = 15+1
f(-3) =16
Answer:
117.99
Step-by-step explanation:
First step is to find the discount
Discount = original price * discount rate
= 135 * 20%
= 135*.20
=27
Take the discount from the original price and that is the new price
new price = original price - discount
= 135-27
=108
Now we need to find the tax
tax = new price * tax rate
= 108 * 9.25%
= 108 * .0925
=9.99
The final price is the new price plus the tax
final price = new price + tax
= 108+9.99
=117.99
Slope is (24--31)/(-6-5) = 55/-11=-5
y-24=-5(x--6)
y-24=-5x-30
y=-5x-6
