Identify the vertex of g(x) = (x+10)^2+2

Mathematics
1 answer:
RoseWind [281]3 years ago
7 0

Answer:

(-10, 2)

Step-by-step explanation:

Compare:

g(x) = (x+10)^2+2

f(x)  = (x - h)^2 + k

Matching these up, term by term, we see that h = -10 and k = 2.  (h, k) represents the vertex of the parabola f(x)  = (x - h)^2 + k.

We conclude that the vertex of this parabola is (-10, 2).

C = 4x + 5y, the value of "x" when C = 51 &amp; y = -3 is:<br> =16.5<br> =9<br> =-16.5<br> =13
Oksi-84 [34.3K]

Answer:

16.5

Step-by-step explanation:

Just put in the values of C and y first into the expression.

C = 4x + 5y

Put in values.

51 = 4x + 5(-3)

Evaluate.

51 = 4x + (-15)

Swap positions.

4x + (-15) = 51

Shift (-15) to the other side and change to (+15).

4x = 51 + 15

    = 66

Find x.

x = 66 ÷ 4

x = 16.5
