Answer:
x³=27
cuberoot√x³=cuberoot of 27
x=3
The dependent variable is y, that represents the years
Answer:
Step-by-step explanation:
10x+10y=-10
9x+10y=18
= 10x+10y=-10
-9x-10y=18
= x=8
step two is to find y:
10x+10y=-10
10(8)+10y=-10
80+10y=-10
10y=-90
y=-9
your answer:
(x,y)= (8,-9)
I believe the answer is B.
It says that he made 100 cupcakes so we know that the total is 100. It says he baked 4 more than so that means that we are adding 4 to some value. It also says that he baked 3 times the total of cupcakes he made last week. Since the total for last week is unknown, we can express that as x.
So, your equation would be 3x+4=100.
Hope this helps!
