Answer:
A is the correct answer
Step-by-step explanation:
To get the fastest answer for these kind of questions, you just have to apply (0, -2) into either one of the 2 equations:
2 * 0 - 6 * (-2) = 12
0 - (-12) =12
0 + 12 = 12 (TRUE)
So the solution will be (0, -2)
Answer:
A. -16x²+64x+8
B. 72 ft.
Step-by-step explanation: A. Expand the perfect square binomial -16(x²-4x+4)+72, dist. -16 (-16x²+64x-64+72), then combine like terms (-16x²+64x+8)
B. Find the abs. max. by looking back at the vertex form. The max is (2,72). Use the y-value for the height.
Answer:
Step-by-step explanation:
The line is passing through 2 points: (0,9 and (3,3)
slope=(9-3)/(0-3)=-2
equation is : y-9=-2(x-0) or y=-2x+9
3(18 - x/3 = -7)
54-x = -21
-x = -75
x = 75
