the answer id d because it's 3 z's so you times that by 4 and you get d.4
-2(3x - 9) + 5x = -10
-6x + 18 + 5x = -10
-6x + 5x = -10 - 18
-x = -28
x = 28 <===
You put the values of x into the equation to work out y, so the y column would be -5, -1, 3, 7 (for question 6)
For question 7, the y column would be 2,2,0,-2
Use these values to draw the graphs :)
Answer:
ax^3+3x^2-bx-6/x^2+3x+2 ( Please specify the equation if I'm wrong)
Step-by-step explanation:
ax^3+3x^2-x^2-bx-3x-6-2
=ax^3+2x^2-x(b+3)-8
