Here's the equation I am going to use:
14(x)+7(x)
x= the number of t-shirts I want to buy (11)
14(11)+7(11)= 231$
$231 is your answer.
I hope this helped you!
Brainliest answer is always appreciated!
1) -10x+y=4
Now, you should substitute x in every situation.
* x=-2 <em>=> -10*(-2)+y=4... 20+y=4... <u>y=-16</u></em>
<em />* x=-1 =>-10*(-1)+y=4... 10+y=4... <u>y=-6</u>
<u />*x=0 => -10*0+y=4... <u>y=4</u>
<u />* x=1 => -10*1+y=4... -10+y=4... <u>y=14</u>
<u />* x=2 => -10*2+y=4... -20+y=4... <u>y=24</u>
<u>2)</u> -5x-1=y
For example: x=0
-5*0-1=-1
<u>

Plug 3 in for r it equals 28.26 so its A
Answer:
