A ghoul is flying at 23 miles per hour when a ghoul policeman stops him. The speed limit is 20 miles per hour. He has to pay a $5.25 fine for every mile over the speed limit. He pays the fine a week late and has a $2 fee for every day he was late. Before he paid his fine he had $278.96. How much did he have AFTER paying his fine?

if x decreases by 4 then y increases by 10

step-by-step explanation:

do have an equation or graph or

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
