5(-2x-3) - 4x -5 =78

Lesechka [4]

Answer:

$x=-7$

Step-by-step explanation:

We want to solve

5(-2x-3) - 4x -5 =78

We expand to get:

$-10x-15-4x-5=78$

We group the similar terms to get:

$-10x-4x=78+20$

Combine similar terms

$-14x=98$

Divide through by -14

$x=\frac{988}{-14}=-7$

Use the parabola tool to graph the quadratic function f(1) = x² + 100 + 24 Graph the parabola by first plotting its vertex and t

Fiesta28 [93]

Answer:

Vertex is (-5, -1)

(-3, 3) is a point on the parabola.

Step-by-step explanation:

f(x) = x² + 10x + 24

Let (h, k) be the vertex

h = -b/2a = -10/2(1) = -5

k = f(-5) = (-5)^2 + 10(-5) + 24

= 25 - 50 + 24 = -1

Vertex is (-5, -1)

Now, let x be some value different than -5, say -3

f(-3) = (-3)^2 + 10(-3) + 24

= 9 - 30 + 24 = 3

So, (-3, 3) is a point on the parabola.
