y=mx+b
3x+4y=8
move 3x to the other side
sign changes from +3x to -3x
3x-3x+4y=-3x+8
4y=-3x+8
divide both sides by 4 to get y by itself
4y/4=-3x/4+8/4
y=-3x/4+2
y=-3/4x+2
answer:
-3/4x+2
Answer:
d
Step-by-step explanation:
because 2/5 × 4x=8/5 and 2/5×9=18/5
ita in d
Answer:
Y=-1
Step-by-step explanation:
y=-2(2)+3
y= -4 +3
-4+3=-1
y=-1

Answer: Choice B 6x^3-4x^2-8x-16</h3>
=========================================
Work Shown:
(3x^2+ 4x+4)(2x-4)
(2x-4)(3x^2+4x+4)
y(3x^2+4x+4) ...... let y = 2x-4
y(3x^2)+y(4x)+y(4) .... distribute
3x^2(y) + 4x(y) + 4(y)
3x^2(2x-4) + 4x(2x-4) + 4(2x-4) .... replace y with 2x-4
3x^2*2x+3x^2(-4)+4x(2x)+4x(-4)+4(2x)+4(-4) .... distribute
6x^3-12x^2+8x^2-16x+8x-16
6x^3-4x^2-8x-16

Below is a diagram which might help you keep track of all the terms
Each cell is the result of multiplying the outer red and green terms. Example: Row 1, column 2 has 2x times 4x = 8x^2 (due to the 2x and 4x outside)
As they are written, they are all linear. I think you meant for the third one to be y=x^2. if that is true then y=x^2 is a quadratic and therefore is the answer
