Jason's age is 1 2 of his brother's age. his brother's age can be represented by the expression 12a - 9. write an expression that can be used to represent the sum of their ages. a) 12a - 5.5 b) 18a - 13.5 c) 18a + 21 eliminate d) (12a-9) 2

Step-by-step explanation:

Jason's age is of his brother's age.

Brother age is

Sum of their ages = Age of Jonson + age of his brother

Jonson's age = half of his brother age

Sum of their ages =  

Take common denominator 2

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

is there supposed to be a diagram or a graph for this one? ?
