Which system of equations can be graphed to find the solution(s) to 2-9x = x/2 -1

i did it myself and i got 4.2 (b) hope its right

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

answer is c

step-by-step explanation:

81/12=324/x

x=48

answer: i believe it is c

step-by-step explanation:

because 5+4=9 so it would be 3^9
