Afunction follows the rule y = -75 - 5x. when the function's output is 25, the equation is 25 = -75 - 5x.

what is the function input when the output is 25?

Using the given equation with the output as 25, solve for X which would be the input value.

25 = -75 - 5x

Add 75 to each side:

100 = -5x

Divide both sides by -5:

x = 100 / -5

x = -20

The input is -20

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
