Sandra saves 14% of her salary for retirement. This year her salary was $1,000 more than in the previous year, and she saved $6,440. What was her salary in the previous year?
Complete the equation. 0.14(x +
= 6,440
Sandra's salary in the previous year was

answer: a

step-by-step explanation:

10.2 units

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)

good luck on ur quiz test or homework. have a good day : )
