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>

Tell me if im wrong sorry if i am.
Answer:
6.9
Step-by-step explanation:
Since you are supposed to decrease the number in the ratio 3:8 or 3/8 you take the small number that is 3 to be the numerator and 8 to be the denominator then multiply it by 18.4.
That is 18.4×3:8= 184/10×3/8=6.9
So to decrease a number you multiply it with the smallest number as the numerator and the big number as the denominator
To increase a number you multiply it with the big number as the numerator and the small number to be the denominator
