A)In June a man

bought x balls
for $25 write down , in terms of
x the cost of each ball (in $)

b) In july he could have bought five more balls for the same amount of money. write down in terms of x the cost of each ball (in $)

c) given that each ball in july had cost 25 cents less. use your answers in a & b to form an equation in terms of x and show that it simplifies to x^2 +5x-500=0

d) solve the equation in (a)

e)hence , write down the number of balls bought in june

the correct answer is 5 6 and 7

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)
