Answer:
z=-3 so 2y+3(-3)=-8, 2y-9=-8, add 9 to both sides 2y=1 divide both sides by 2, y=1/2, so 3x+4(1/2)+-3=-2, 3x+2-3=-2, 3x-1=-2, add 1 to both sides, 3x=-1, divide both sides by 3, x=-1/3
Answer:
B should be the answer but it could but C
They would be perpendicular. hope this helps.
Answer:
y=-4x+4
Step-by-step explanation:
The slope is Delta Y over Delta Y so the slope is -4. The Y intercept is at (0,4) sot the equations is y= - 4x +4
Answer: B. 77
Sub x =6 into the given expression
4x^2 - 12x + 5
= 4(6)^2 - 12(6) + 5
= 144 - 72 + 5
= 77
