Mr. Milton had 1,200 in his saving account at the beginning of the year. if his account has a balance of 1,230 at the end of the year, what is the percent increase of his balance

2.5% increase

Step-by-step explanation:

1230 - 1200 = 30

30/1200 = 0.025

0.025 x 100 = 2.5%

step-by-step explanation:

ask goog great chance of finding the solution there

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)
