Answer:
the vertex is (-7, -63)
Step-by-step explanation:
x^2 + 14x - y - 14 = 0
x^2 + 14x = y + 14 (to isolate the x)
x^2 + 14x + 49 = y + 14 + 49
(x+7)^2 = y + 63
now we convert to vertex form, which is y = a(x – h)2 + k :
(x+7)^2 = y + 63
y = (x+7)^2 - 63
The vertex in vertex form is shown as (h, k) from y = a(x – h)2 + k, so in this case, h = -7 and k = -63. H is the x-coordinate as shown while k is the y-coordinate. Thus, the vertex is (-7, -63)

Answer:
the first graph
Step-by-step explanation:
The first one - y = 1/4x + 3/2.
sorry im a bit late but hopefully this helps
Remember that the rule with multiplying exponents with the same base is to add the exponents together.
In this case:
10^12 is your answer.
The soccer team won 104 games.
To find this, you multiply 160 by 65% (0.65), and it will give you 104.
To get 65 percent into a decimal, you simply divide 65 by 100.
I hope this helps!
