Answer:
![[-9, -6]](https://tex.z-dn.net/?f=%5B-9%2C%20-6%5D)
Step-by-step explanation:
{−5x + 8y = −3
{3x - 5y = 3
⅗[−5x + 8y = −3]
{−3x + 4⅘y = −1⅘ >> New Equation
{3x - 5y = 3
______________
![\frac{-\frac{1}{5}y}{\frac{1}{5}} = \frac{2\frac{1}{5}}{\frac{1}{5}}](https://tex.z-dn.net/?f=%5Cfrac%7B-%5Cfrac%7B1%7D%7B5%7Dy%7D%7B%5Cfrac%7B1%7D%7B5%7D%7D%20%3D%20%5Cfrac%7B2%5Cfrac%7B1%7D%7B5%7D%7D%7B%5Cfrac%7B1%7D%7B5%7D%7D)
[Plug this back into both equations above to get the x-coordinate of −9]; ![-9 = x](https://tex.z-dn.net/?f=-9%20%3D%20x)

Answer:
2c
Step-by-step explanation:
Using the rule of exponents
×
⇔ ![a^{(m+n)}](https://tex.z-dn.net/?f=a%5E%7B%28m%2Bn%29%7D)
Given
× 2![c^{7}](https://tex.z-dn.net/?f=c%5E%7B7%7D)
=
× 2 = 2c
Answer:
There are mathematics you could purchase that has answer sheets, what grade you in?
V = πr^2h
V = π(5 m)²(11 m)
V = 275π m³
D. V = 863.9 m³
The original price is $21.59
take 19 divide by 0.88 (from 100% - 12%)
