Determining If an Equation Is a Direct Variation Quick
Check
Determine whether or not the equations represent a direct variation. Sort the equations into the appropriate catego
Direct Variation

y = 3x
X=-1
y = (217
-0.5x = y
y = 22x + 7
y = 4

a - base

b - exponent

so,

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
