X=-1
x-7=2x-6
subtract x from both sides.
-7=x-6
add 6 on both sides.

X - 7 = 2x - 6 Add 6 to both sides
x - 1 = 2x Subtract x from both sides
-1 = x Flip it around so it's easier to read
x = -1

Check your answer by substituting -1 in for x.

(-1) - 7 = 2(-1) - 6 Simplify 2 times -1
(-1) - 7 = -2 - 6 Simplify both sides
-8 = -8

So, x = -1 .

What is the equation of this parabola in vertex form

attashe74 [19]

first off, let's notice the parabola is a vertical one, therefore the squared variable is the x, and the parabola is opening upwards, meaning the coefficient of x² is positive.

let's notice the vertex, or U-turn, is at (-2, 2)

$\bf ~~~~~~\textit{parabola vertex form} \\\\ \begin{array}{llll} \boxed{y=a(x- h)^2+ k}\\\\ x=a(y- k)^2+ h \end{array} \qquad\qquad vertex~~(\stackrel{-2}{ h},\stackrel{2}{ k}) \\\\\\ y=+1[x-(-2)]^2+2\implies y=(x+2)^2+2$
