Solve the following equation for x.

Vaselesa [24]

Solve for x (isolate/get x by itself)

$\frac{1}{4}x-7=\frac{3}{8}x-5$ Add 5 on both sides

$\frac{1}{4}x-7+5=\frac{3}{8}x-5+5$

$\frac{1}{4}x-2=\frac{3}{8}x$ Subtract 1/4x on both sides

$\frac{1}{4}x-\frac{1}{4}x-2=\frac{3}{8}x-\frac{1}{4}x$

$-2=\frac{3}{8}x-\frac{1}{4}x$ Make the denominators the same of the fractions in order to combine them. Multiply 2 to the top and bottom of 1/4x

$-2=\frac{3}{8}x-\frac{2}{8}x$

$-2=\frac{1}{8}x$ Multiply 8 on both sides

$-2(8)=(8)\frac{1}{8}x$

-16 = x

Find the average rate of change of the function from <img src="https://tex.z-dn.net/?f=x_%7B1%7D" id="TexFormula1" title="x_{1}"

meriva

Hi there!

$\large\boxed{\text{Average rate} = 2}$

Use the following equation to solve:

$\text{Average rate} = \frac{f(x_{2}) - f(x_{1})}{x_{2} - x_{1}}$

Solve for the y-values of the equation at the given x values:

f(1) = 1² - 4(1) + 10 = 7

f(5) = 5² - 4(5) + 10 = 15

Plug the solved values into the equation:

$\text{Average rate} = \frac{15 - 7}{5-1}$

Simplify:

$\text{Average rate} = \frac{8}{4} = 2$
