Answer:
Step-by-step explanation:
-------------------------- (1)
-------------------------- (2)
Multiply Eq. (1) by 13 and (2) by 9
<u>Equation (1):</u>
--------------------(3)
<u>Equation (2):</u>
------------------------(4)
Subtract Eq. (2) from (1)
39x - 36x = -264
3x = -264
Dividing both sides by 3
x = -88
![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
<u>Put x = -88 in Eq. (1)</u>
3(-88)+9y³ = -21
-264 + 9y³ = -21
9y³ = -21 + 264
9y³ = 243
Dividing both sides by 9
y³ = 27
Taking cube root on both sides
y = 3
Ordered Pair = (x,y) = (-88,3)
Hope this helped!

I do because x divided by y is the constant because y=kx
You would solve, so 1162/4. Show the steps of you dividing it down on notes of paper
Volume of a cube is Side to the third power ( S^3)
S = 3.2 meters
Volume = 3.2^3
Volume = 32.768 cubic meters (cm^3)
You may need to round the answer.. The problem doesn't say how many decimal places are needed.
