Answer:
Hi, I just wanted to say that I got this question a few days ago on my test!
I haven't gotten my grade yet and I dont know if I got it right but I hope you figure it out! Best of luck to you!
-10y + 9x = - 9....A
10y + 5x = - 5.....B
You should see right away that -10y and 10y cancel out.
We are left with
14x = -14
x = -14/14
x = -1
Plug x = -1 into EITHER equation A or B to find y.
I will use equation A.
-10y + 9(-1) = - 9
-10y - 9 = - 9
-10y = - 9 + 9
- 10y = 0
y = 0/-10
y = 0
Done!
The answer is A because “x” is the number of jeans purchased so it would be the price per jean times number of jeans being purchased
The equation that does not belong is C because it is the only one that contains exponents
Answer:
<2 and <6 are complementary angles
Step-by-step explanation:
<2 and <3 are complementary angles since they add to 90
<3 and <6 are vertical angles so they are equal
<3 = <6
Replace <3 with <6
<2 and <6 are complementary angles
