If you would like to find the solution to the system of equations, you can do this using the following steps:

4c = 3d + 3
c = d - 1
___________
4 * (d - 1) = 3d + 3
4d - 4 = 3d + 3
4d - 3d = 3 + 4
d = 7

c = d - 1 = 7 - 1 = 6

The correct result would be <span>c = 6, d = 7.</span>

The function f(x) = x2 + 10x – 3 written in vertex form is f(x) = (x + 5)2 – 28. What are the coordinates of the vertex?

Alexxandr [17]

Vertex form uses the following formula:

$y = a(x-h)^2 + k$

Identify the values of h and k in your function:

$(x+5)^2 - 28$
$h = -5, k = -28$

The vertex is found with the following point:

$(h,k)$
$\text{Vertex: (-5, -28)}$

The vertex will be found at (-5, -28).
