Answer:

x = 0, x = 1

Step-by-step explanation:

Given

x² = x ( subtract x from both sides )

x² - x = 0 ← factor out x from each term on the left side

x(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x = 0

x - 1 = 0 ⇒ x = 1

What is the vertex of the function f(x) = x2 + 12x?

Sophie [7]

We can start by figuring out the axis of symmetry.

y = x² + 12x = x (x + 12)

So roots are x = -12 or 0

Therefore axis of symmetry is x = (-12 + 0) / 2 = -6

We got x-coordinate of vertex. Now plug in x=-6 to solve for y.

y = (-6)² + 12(-6) = 36 - 72 = -36

Therefore vertex is (-6, -36).

Solving systems of equations using substitution p=q+3 4p+3q= -30

patriot [66]

4(q+3) + 3q = -30
4q +12 + 3q = -30
7q+12= -30
7q = -12-30
7q = -42
q = -6
p = -3
