5(4 − x) = −5x + 20 i need help
adoni [48]

Answer:

x=4

Step-by-step explanation:

-5(4-x)=-5x+20

We simplify the equation to the form, which is simple to understand

-5(4-x)=-5x+20

Reorder the terms in parentheses

+(-20+5x)=-5x+20

Remove unnecessary parentheses

-20+5x=-5x+20

We move all terms containing x to the left and all other terms to the right.

+5x+5x=+20+20

We simplify left and right side of the equation.

+10x=+40

We divide both sides of the equation by 10 to get x.

x=4

What is the axis of symmetry for f(x) = x2 + 4x + 6
mixer [17]

Answer:

x = -2

Step-by-step explanation:

In order to find the axis of symmetry, we will have to find the x-value of the vertex.

Vertex = (-b/2a, f(-b/2a))

In x² + 4x + 6,

a = 1 , b = 4 , c = 6

Vertex = (-4/2,f(-4/2))

Vertex = (-2,f(-2))

We have found the x-value of the vertex which is -2.

Hence, line/axis of symmetry is x = -2
