We can suggest this equation:
5x=40º+x
5x-x=40º
4x=40º
x=40º/4
x=10º

Answer: x=10º

The 5x and the combination of (40° + x) are "vertical angles".
Vertical angles are equal.
So
5x = 40° + x

Subtract 'x' from each side: 4x = 40°

Divide each side by 4 : x = ?

Which graph shows a rate of change of 1/2 which is a fraction between –4 and 0 on the x-axis?

irakobra [83]

By definition, we have that the average rate of change is given by:

$AVR = \frac{y2-y1}{x2-x1}$

Substituting values we have:

$AVR = \frac{3-1}{0-(-4)}$

Rewriting we have:

$AVR = \frac{2}{0+4}$

$AVR = \frac{2}{4}$

$AVR = \frac{1}{2}$

Therefore, the graph that has an AVR of 1/2 is the graph of the linear function.

Answer:

graph shows a rate of change of 1/2 is the linear function

Find what percent 591 is of 2364

kati45 [8]

To find the percent you would divide 591 by 2364
591/2364=.25
.25*100 = 25%
Does that make sense?

10 exponent negative 9 divided by 10 exponent negative 3

anygoal [31]

$\frac{x^a}{x^b}=x^{a-b} \\ x^{-a}= \frac{1}{x^a} \\ \\ \\ \frac{10^{-9}}{10^{-3}} =10^{-9-(-3)}=10^{-9+3}=10^{-6}= \frac{1}{10^6} = \frac{1}{1000000} =0,000001$
