Answer:

x = - 1

Step-by-step explanation:

Given a parabola in standard form , f(x) = ax² + bx +c ( a ≠ 0 )

Then the axis of symmetry is calculated using

x = - \frac{b}{2a}

f(x) = x² + 2x - 8 ← is in standard form

with a = 1 and b = 2 , then axis of symmetry is

x = - \frac{2}{2} = - 1, that is

x = - 1

15 POINT 1 QUESTION<br> ITS ALL UP TO YOU!!!!
Anni [7]

First, we can simplify the left side. (6+8x)/2 is equal to 3 + 4x. We can put the equation together at this point.

3 + 4x = 5x

we can subtract 4x from both sides to get our final answer,

3 = x, or x = 3. :)

Find the vertex of an angle of an isosceles triangle if one base angle is 8 less than half the vertex?
skad [1K]
Vertex angle = x
1 base angle = 1/2x - 8

180-x = (1/2x-8)x2
180-x = x-16
196-x = x
196 = 2x
x=98
