Maggie's brother is 10 years younger than twice her age. the sum of their ages is 29. how old is maggie? maggie is old.

Let M be the age of Maggie and B the age of her younger Brother:

Rewrite the problem from English language to Math's:

B = 2.M - 10 (1)

and  M + B = 29 (Given) OR    B  =  29 -M (2)

Plug 2) into 1):

29 -M = 2.M -10

29 + 10 = 3 M →→3M = 39 and M = 39/3 = 13

Replace M by 13 and you will find B =6

Then Maggie = 13 year old and her brother B = 6 year old

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)
