Answer: 8.4
Explanation: Substitute y = 0.8 into the equation.
4x + 8(0.8) = 40
4x + 6.4 = 40
4x = 33.6
x = 8.4
Answer:
d. y-3 = f(x)
Step-by-step explanation:
we don't know what f(x) is. but we can see that the red line is 3 units above the black line. so we are adding 3 to whatever f(x) is. so the red line should have the equation
y = f(x) +3
subtract 3 from both sides
y-3 = f(x)
Answer:
y=4x-28
Step-by-step explanation:
slope is 4
y-4=4(x-8)
y-4=4x-32
y=4x-32+4
y=4x-28
the slopes of parallel lines are equal
