Answer:
x = 10
Step-by-step explanation:
Given
+ 13 =
( multiply through by 10, the LCM of 5 and 2 to clear the fractions )
2x + 130 = 15x ( subtract 2x from both sides )
130 = 13x ( divide both sides by 13 )
10 = x
Answer:
Vertex is (-4, -18)
Step-by-step explanation:
f(x) =
Let (h, k) be the vertex
An easy way to find h is to use the formula h = -b/2a
In your case where f(x) = a = 2 and b = 8
So, h = -8/2(1) = -8/2 = -4
Substitue -4 in for x to find k
k = () + 8(-4) - 2
= (16) - 32 - 2
= 16 - 32 - 2
= -18
Vertex is (-4, -18)
Note: Another way to find the vertex is to complete the square, but this can really be difficult in some cases
