How to solve 7 2/6 + 8 5/6

1 answer:

3 0

Separate them first.
7+8=15
5/6+2/6=7/6
There can't be 7/6, so it becomes 1 and 1/6,
15+1+1/6=16 1/6
The answer is 16 1/6.

What is the vertex of y = x2 + 2x +2 O (1,-1) O (2,-2) O (1, 2) 0 (-1, 1)

fredd [130]

Answer:

vertex = (- 1, 1 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

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

y = x² + 2x + 2 ← is in standard form

with a = 1 and b = 2 , then

x = - $\frac{2}{2}$ = - 1

substitute x = - 1 into the equation for y- coordinate of vertex

y = (- 1)² + 2(- 1) + 2 = 1 - 2 + 2 = 1

vertex = (- 1, 1 )
