Write the equation of the line perpendicular to y = -5/2x + 1 that passes through the point (-5, -5).

y = 2/5x - 3

Step-by-step explanation:

First, we have to know what the slope is. Being perpendicular to -5/2, the slope becomes 2/5.

Then, you substitute the slope and given point into the equation to find the y-intercept.

y = 2/5x + b

(-5) = 2/5(-5) + b

(-5) = (-2) + b

b = -3

So, the equation is

y = 2/5x - 3

y=2/5x−3.

Step-by-step explanation:

Basically, you just convert it into point slope form with the new slope and points and then convert it back into slope intercept.

y+5=2/5(x+5)

y+5=2/5x+2

y=2/5x+2-5

y=2/5x−3.

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

happy to

pls mark as brainliest

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
