First, we need to transform the equation into its standard form (x - h)²=4p(y - k).
Using completing the square method:
y = -14x² - 2x - 2
y = -14(x² + 2x/14) - 2
y = -14(x² + 2x/14 + (2/28)²) -2 + (2/28)²
y = -14(x + 1/14)² - 391/196
-1/14(y + 391/196) = (x + 1/14)²
This is a vertical parabola and its focus <span>(h, k + p) is (-1/14, -391/196 + 1/56) = (-1/14, -775/392).
Or (-0.071,-1.977).</span>
Subtract Y from both sides
H < W - Y
Answer:
250 x 3 = 750g
750g is your final answer
Hello from MrBillDoesMath!
Answer: 1/12
Discussion:
We solve 5/12 + x = 1/2 for x. Begin by subtracting 5/12 from each side
5/12 - 5/12 + x = 1/2 - 5/12
0 +x = 6/12 - 5/12 (as 1/2 = 6/12)
So x = 1/12

The answer is 2x-4
Factor out 5 from the expression and then reduce the numbers with the greatest common factor 5
