Q.9) Rahul's mother's age is 5 less than 4 times his age. What is his age if his mother is 39 years old? *
pls ans I will follow you​

4x-5=39

4x= 39+5

x=44/4

x=11 yrs

his age will be 11 year

Explanation:

let rahul's age be x

then his mother's age=4x-5

4x-5=39

4x=39+5

4x=44

x=44/4

x=11

a) 7x=7

step-by-step explanation:

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)
