The answer is actually A. Sides are named by their angles.
3x + 6y = -2......multiply by -5
15x + 30y = -10
--------------------
-15x - 30y = 10 (result of multiplying by -5)
15x + 30y = -10
--------------------add
0 = 0
there are infinitely many solutions
Answer:
2 years
Step-by-step explanation:
If you have $9000 in the saving account, and you take $500, you are left with:
$9000 - $500 = $8500
in one year you will have 3% more of the 8500 which is:
8500/100*3 = $255
so in one year the number on your savings account is:
8500 + 255 = $8755
and by the next year you will have 3% more of the 8755 which is:
8755/100*3 = $262.65
so in two years the number on your savings account is:
8755 + 262.65 = $9017.65
which is a little bit more than the $9000.
so it will take 2 years until the calance again reaches $9000
Please mark braniliest if this reaches 2 answers because I want to get to Expert ;w;
Brandon’s method is incorrect because if we continue the pattern, 9 times 1/2 is 4.5. It’s obvious that the square root of 9 is 3. Similarly, the square root of 16 is 4, but 16 times 1/2 is 8. Any number you will try after that won’t work.
