Is the expression 2 • 4 ^ x equal to the expression 8 ^ x ? Explain your answer

It depends on the value of x

Step-by-step explanation:

If x=1, then yes

Exponents come before multiplication, so even if 2*4=8, 2*4^2 is not equal to 8.

Ex:

2*4^2=32

8^2=64

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)
