A water reserve follows the path given by y=2x+20, where each unit represents 1 kilometer. A town is located at (50, 5). The town’s laws require that the water reserve be the shortest possible distance from the town. How close does the water reserve come to the town?

sss (side, side, side)

sas (side, angle, side)

asa (angle, side, angle)

aas (angle, angle, side)

hl (hypotenuse, leg)

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

i believe it's a.

i'm not sure on this one, most likely correct.

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
