Describe how to solve 4x = 36.

netineya [11]

Answer:

hope this helps! :)

Step-by-step explanation:

4x=36

divide both sides of the equation by 4

4x / 4 = 36 / 4

Any expression divided by itself equals 1

x= 36 / 4

Calculate the quotient

36/4 = 9

<u>x=9</u>

What is the answer to -7+x=x/10-16

Law Incorporation [45]

We first get rid of the fraction by multiplying both sides by 10

this gives us: -70+10x=x-160

subtract x from both sides

this gives us: =-70+9x=-160

add 70 to both sides

this gives us 9x=-90

divide both sides by 9

this gives us x=-10

If f(x)=x squared-2x and g(x) = 6x+4 for which is a value of x does (f+g)(x) =0

ra1l [238]

Answer:

For $x = -2$

Step-by-step explanation:

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

$ax^{2} + bx + c, a\neq0$ .

This polynomial has roots $x_{1}, x_{2}$ such that $ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})$ , given by the following formulas:

$x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}$

$x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}$

$\Delta = b^{2} - 4ac$

In this question:

$f(x) = x^2 - 2x$

$g(x) = 6x + 4$

$f(x) + g(x) = (f+g)(x) = x^2 - 2x + 6x + 4 = x^2 + 4x + 4$

Which is a value of x does (f+g)(x) =0

$x^2 + 4x + 4$

Quadratic equation with $a = 1, b = 4, c = 4$

$\Delta = 4^{2} - 4*1*4 = 0$

$x_{1} = \frac{-4 + \sqrt{0}}{2} = -2$

$x_{2} = \frac{-4 - \sqrt{0}}{2} = -2$

For $x = -2$
