Answer:
-25
Step-by-step explanation:
(1) y = -2x²
(2) y = 2x² + k Subtract (1) from (2)
0 = 4x² + k Subtract 4x² from each side
k = -4x²
The parabolas are <em>symmetrical about the y-axis.</em>
Segment AB = 5, so x = +2.5 and x = +2.5.
k = -4(±2.5)² = -4 × 6.25 = -25
Answer:
-1
Step-by-step explanation:
2 × (-1²) + 1 = 2 × (-1) + 1 = -2 + 1 = -1
360 ft * 160ft = 57,600 ft squared
I'm not sure, this question was kind of confusing
x= 18
let me show you the workout
6x+1+12x-5=32
Combine like terms .Combine 6x+12=18x
18x-4=32 Subtract -4 from 32
18x=36 Divide by 18 and
X=16
Hoped this helped Im not sure if this is right
