Answer:
I = 91.125
Step-by-step explanation:
Given that:
where E is bounded by the cylinder
and the planes x = 0 , y = 9x and z = 0 in the first octant.
The initial activity to carry out is to determine the limits of the region
since curve z = 0 and
∴ 

Thus, z lies between 0 to 
GIven curve x = 0 and y = 9x

As such,x lies between 0 to 
Given curve x = 0 ,
and z = 0,
y = 0 and

∴ y lies between 0 and 9
Then 











I = 91.125
x will represent the first unknow number
6x will represent the second number
the two numbers together will equal 21
6x + x = 21 combine like terms
7x =21 divide both sides by 7
x =3
Hope that helps.
brainliest is always appreciated.
250/5 = 50.....so each person is stacking 50 chairs...
50/20 = 2.5 minutes....so it takes each person 2.5 minutes to stack 50 chairs.
so ur answer is 2.5 minutes
Answer:
x = 2, y = 1
Step-by-step explanation:
- 7x + 5y = 19
- -7x - 2y = -16
Use the elimination method to solve the system of equations. Add the terms from top to bottom. 7x and -7x cancel out.
0 + 3y = 3
Divide both sides by 3.
y = 1
Substitute 1 for y into the first equation.
7x + 5(1) = 19
7x + 5 = 19
Subtract 5 from both sides.
7x = 14
Divide both sides by 7.
x = 2
