^^To solve you must use the fractional exponent rule.

I dont quite understand what the question is asking but thats what I have to help :)

Match each graph with the correct equation written in<br> standard form. Explain your reasoning.

My name is Ann [436]

The graphs and their equations are:

Line 1: 6x - 2y = -10
Line 2: 9x - 9y = -45
Line 3: 3x - 12y = -60

<h3>How to determine the equations of the graphs</h3>

The three lines are linear equations, because they are all straight lines.

Also, the lines have the same y-intercept (this is so, because they cross the y-axis at the same point), but they have the same slope

Next, we rewrite the equations in slope-intercept form.

So, we have:

$3x - 12y = -60$

Divide through by -12

$-0.25x +y = 5$

Make y the subject

$y = 0.25x + 5$

$6x - 2y = -10$

Divide through by 2

$3x - y = -5$

Make y the subject

$y = 3x + 5$

$9x - 9y = -45$

Divide through by -9

$-x + y = 5$

Make y the subject

$y = x + 5$

Line 1 has the highest slope, while line 3 has the least slope.

So, we have the following equations:

Line 1: 6x - 2y = -10
Line 2: 9x - 9y = -45
Line 3: 3x - 12y = -60

Help please and thank you

Remember
$(a^b)^c=a^{bc}$
and
$\frac{x^a}{x^b}=x^{a-b}$

so

$\frac{(7^2)^5}{7^{-6}}=$
$\frac{7^{2*5}}{7^{-6}}=$
$\frac{7^{10}}{7^{-6}}=$
$7^{10-(-6)}=$
$7^{10+6}=$
$7^{16}$

the answer is D

What is x/13-5=25/26

Juliette [100K]

$\frac{x}{13} -5=\frac{25}{26}$ Add 5 on both sides

$\frac{x}{13}=\frac{25}{26}+5$ Make the denominators the same

$\frac{x}{13}=\frac{25}{26}+\frac{130}{26}$

$\frac{x}{13}=\frac{155}{26}$ Multiply 13 on both sides

$(13)\frac{x}{13}=(13)\frac{155}{26}$

$x=\frac{2015}{26}$

$x=\frac{155}{2}$
