Answer:

c 3

Step-by-step explanation:

put the rise (change in y) over run (change in x)

find the difference between the y points: 2 and 8

8 minus 2 is 6, so that's your rise

then find the difference between your x points: 2 and 4

4 minus 2 is 2, so that's your run

rise / run = 6/2, which simplified is just 3

A small business averages $5,500 per month in online revenue, plus another $300 per salesperson per month. Which graph shows all

valentinak56 [21]

Answer: A

Step-by-step explanation:

First take 5,500 and subtract it from 7,300 to get 1,800. Then divide 1,800 by 300 to get 6. Thus, there must be less than or equal to 6 salespeople.

Square root of 144 X^7 Y^5

LekaFEV [45]

The first step to solving this is to factor out the first perfect square
$\sqrt{12^{2} x^{7} y^{5} }$
now factor out the second perfect square
$\sqrt{ 12^{2} x^{6} X x y^{5} }$
then factor out the second perfect square
$\sqrt{ 12^{2} x^{6} X x y^{4} X y}$
the root of a product is equal to the product of the roots of each factor
$\sqrt{ 12^{2} }$ $\sqrt{ x^{6} }$ $\sqrt{ y^{4} }$ $\sqrt{xy}$
reduce the index of the radical and exponent with 2 of the first square root
12 $\sqrt{ x^{6} }$ $\sqrt{ y^{4} }$ $\sqrt{xy}$
reduce the index of the radical and exponent with 2 of the second square root
12x³ $\sqrt{ y^{4} }$ $\sqrt{xy}$
reduce the index of the radical and exponent with 2 of the third square root
12x³y² $\sqrt{xy}$
this means that the correct answer to your question is 12x³y² $\sqrt{xy}$ .
