Which of the following equations has a slope of -3 and a y-intercept of 8? Oy=-3x + 8
Oy=8x - 3
y=-3x – 8
Oy= 8x +3

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

where is the picture? i can

in my opinion, i think that both of them aren't that hard, but if i had to choose one, i would say algebra because you have to do exponents and everything.
