Please tell me the answer! I'm crying in confusion! :(
Inessa [10]
First, change the fractions to a common denominator, which is 21. 

so 3/7 * 3/3  = 9/21

1/3 * 7/7 = 7/21

Add the two together

9/21 + 7/21 = 16/21

Then take 21/21 - 16/21 = 5/21

There is 5/21 of the pizza left.

F(x) = 2x2 + 12x + 1<br> Determine the vertex
Gnom [1K]

Answer:

Step-by-step explanation:

The vertex would be the highest/lowest point so lets factor this first

when we factor we get

2(x^2+6x+8)

2(x+4) (x+2)

Using zero product property we find the 2 x values and x intercepts are

-4 and -2

the middle point of these points is -3

Substitute -3 for x and solve

2(-3+4) (-3+2)

2 * 1 *  -1

2*-1

-2

(-3,-2) is the vertex
