Hi!

$5x^2 * 6x^2 *x$

$30x^2x^2x$

$=30x^5$

Explanation: <u><em>First you had to multiply by the numbers with 5*6=30. It gave us =30x^2x^2x. You can also used apply exponent rule: a^b*a^c=a^b+c, and x^2x^2x=x^2+2+1=x^5. And it gave us the answer is =30x^5. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie</em></u>

An electrician earns $110 after his first hour of working for a client. His total pay based on the number of hours worked can be

VLD [36.1K]

I don't like trying all of them so I will make up my own which will probably be in the answers
so equation is
f(x)=pay
x=hours worked
solve so
f(1)=110
f(2)=130
f(3)=150
f(4)=170

they seem to be increasing in 20 increments so therefor the pay is linked to hours times 20 so that measn that every hour he works, he gets 20 dollars
therefor the answer is f(n+1)=f(n)+20 since we know that 1 hour=$20 so n+1hour=n+$20

the answe ris f(n+1)=f(n)+20

Graph a line that contains the point (-5,-3) and has a slope of -2

Tpy6a [65]

Answer:

-->

Step-by-step explanation:

Graph (-5,-3) and use the slope, -2, to find another point. -2 can also be written as $-\frac{2}{1}$

$\frac{rise}{run} =\frac{-2}{1}$ and $\frac{rise}{run} =\frac{2}{-1}$ **

Use both. This works because either way, they will lie on the same line with the same slope. So, starting at (-5,-3), go down two points (-)* and to the left 1 (+)*, then, starting at (-5,-3) again, go up two points (+)* then to the right 1 point (-)*.

* If the number is negative, you either go down or to the right. If the number is positive, you go up and to the left.

**Rise over run refers to the change in the y-axis and the change in the x-axis: $\frac{rise}{run} =\frac{y-axis}{x-axis}$ . Only one number is negative because, if both were negative, that would make a positive number, but the slope is -2, not 2.
