What is the solution of 3 sqrt x+8=-4?

Step-by-step explanation:

The given equation is .

We cube both sides of this equation to obtain;

.

This implies that;

We group similar terms to obtain;

We simplify the right hand side of the equation to obtain;

Therefore x=-72 is the solution of the given equation.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
