Which expression is equivalent to the given expression? (4m2n)2
2m5n
A 8m9n3
B 4m9n3
C 8m-1n
D 4m-1n​

C. 8m`¹.n

Step-by-step explanation:

((4m²n)²) /(2m^5.n)

= (16m⁴n²)/(2m^5.n)

= 8m`¹n

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)
