Answer:

- 1

Step-by-step explanation:

The product of the slopes of lines perpendicular to each other is - 1

Given y = 4x - 5 with slope 4

y = - $\frac{1}{4}$ x - 5 with slope - $\frac{1}{4}$ then

4 × - $\frac{1}{4}$ = - 1 proving the lines are perpendicular

0.8(5x+15)=2.6-(x+3)

elena55 [62]

0.8(5x + 15) = 2.6 - x + 3 Use the Distributive Property
4x + 12 = 2.6 - x + 3 Combine like terms (2.6 and 3)
4x + 12 = 5.6 - x Add x to both sides
5x + 12 = 5.6 Subtract 12 from both sides
5x = -6.4 Divide both sides by 5
x = -1.28
