Michael is training for a 10 mile race. during the first week, he runs 2 miles. each week he runs one and a half times what he ran the previous week. if he only runs once a week, how many total miles has he run by the 5th week?
a) 10.13 miles
b) 15.19 miles
c) 16.25 miles
d) 26.38 miles

D) 26.38

Step-by-step explanation:

Multiply each week by 1.5 and it says total, so add all the number up to get 26.38

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)

126 maybe. sorry
