The sum of 8 and 5 times a number is 43. which equation below can be used to find the unknown number? a. (8 + 5)n = 43 b. 8 + 5n = 43 c. (8 + n) = 43 d. 8(5n) = 43

A

Step-by-step explanation:

"The sum of 8 and 5 times a number is 43" gives keywords.

Sum - addition +

Times - multiplication *

is - equal =

a number - variable n

To write it use these keywords:

(8+5)n=43

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

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)
