Answer:

x=13

Step-by-step explanation:

since they are vertical angles, they equal each other so set both angles to have them equal each other to find x

$8x - 12 = 6x + 14$

Add 12 on both sides

$8x = 6x + 26$

Subtract tax from both sides

$2x = 26$

Divide by 2 for both sides

$x = 13$

Give the following equations determine if the lines are parallel perpendicular or neither

GaryK [48]

In order to determine whether the equations are parallel, perpendicular, or neither, let's simply each equation into a slope-intercept form or basically, solve for y.

Let's start with the first equation.

$\frac{6x-5y}{2}=x+1$

Cross multiply both sides of the equation.

$6x-5y=2(x+1)$ $6x-5y=2x+2$

Subtract 6x on both sides of the equation.

$6x-5y-6x=2x+2-6x$ $-5y=-4x+2$

Divide both sides of the equation by -5.

$-\frac{5y}{-5}=\frac{-4x}{-5}+\frac{2}{-5}$ $y=\frac{4}{5}x-\frac{2}{5}$

Therefore, the slope of the first equation is 4/5.

Let's now simplify the second equation.

$-4y-x=4x+5$

Add x on both sides of the equation.

$-4y-x+x=4x+5+x$ $-4y=5x+5$

Divide both sides of the equation by -4.

$\frac{-4y}{-4}=\frac{5x}{-4}+\frac{5}{-4}$ $y=-\frac{5}{4}x-\frac{5}{4}$

Therefore, the slope of the second equation is -5/4.

Since the slope of each equation is the negative reciprocal of each other, then the graph of the two equations is perpendicular to each other.

Need help I don’t understand what it means

Answer:

b) - 10

Step-by-step explanation:

<h3>Average rate of change:</h3>

To find the average rate of change, we have divide the change in y of f(x) , by the change in x(input).

$\sf \boxed{\text{\bf Average rate of change = $\dfrac{f(b)-f(a)}{b-a}$}}$

a = 4 ; f(a) = -17

b = 6 ; f(b) = -37

$\sf Average \ rate \ of \ change = \dfrac{-37-[-17]}{6-4}$

$\sf =\dfrac{-37+17}{2}\\\\=\dfrac{-20}{2}\\\\=-10$
