Answer:
-12
Step-by-step explanation:
Note that when x < 6, you will use the expression -4x
f(x) = -4x
Plug in 3 for x
f(3) = -4(3)
Simplify. Multiply
f(3) = -4(3)
f(3) = -12
-12 is your answer
Answer:
A. y(3) + x = total cost
B. Shoe rental is $2.
Step-by-step explanation:
A. 4(3) + 2 = 14
B. If 4(3) = 12, and the total cost is $14. Then the shoes cost $2.
4(3) = 12 + 2 = 14
Slope = (10 -5)/(2+3) = 5/5=1
y = mx + b
5 = 1(-3) + b
b =8
so equation y = x +8
