The vertex is (-1,1)

Explanation

The vertex formula to find the x coordinate of the formula is -b/2a

So we plug in the values into the formula which is

-4/2(2)

Simplify it

-4/4
=-1
-1 is now the x cord of the vertex.

So now we will plug in the x into the quadratic equation which is 2x^2+4x+3

2(-1)^2 + 4(-1) + 3 = 2 -4 +3

Simplify it

5 - 4= 1

Y=1
So the Coordinates of the vertex is (-1,1)

Can someone help me plz I don’t really understand this. I just have to find the value of x
Julli [10]
Angle 5x+7 is equal to the the sum of its remote interior angles, which we are given as x+15 and 6x-26.  Therefore, 5x+7=x+15+6x-26.  We will combine like terms to get 5x+7=7x-11.  Move the 7x over to the other side by subtraction and the 7 to the other side by subtraction to get -2x = -18.  That leaves us with an x value of 9.  There you go!
