Hey There!
8x^46=8x(40+
We move all terms to the left:
8x^46-(8x(40+)=0
As with any "solve for ..." problem, you start by looking at the operations performed on the variable of interest. Here, when you evaluate this expression according to the order of operations, you
- add b1
- multiply by (h/2)
When you want to solve for b2, you undo these operations in reverse order. To undo multiplication by a fraction, you multiply by the inverse (reciprocal) of the fraction. To undo addition, you add the opposite.
Whatever you do must be done to both sides of the equation.
Here we go ...
... (2/h)A = b1 + b2 . . . . . we undid the multiply by h/2, by multiplying by 2/h
... (2/h)A - b1 = b2 . . . . . we undid the addition of b1 by adding the opposite of b1
Then your solution is
... b2 = 2A/h - b1
If you want to, you can combine these terms over a single denominator to get
... b2 = (2A -h·b1)/h
Answer:
166 2/3π
Step-by-step explanation:
Area: 4πr² = 100π
r² = 25
r = 5
Volume = 4/3 * π * 5³ = 500/3 π = 166 2/3π
You would set your equation up as basically f(x)-g(x), so:
(3x-4)-(x+2)
combine your like terms and you should have your answer:
2x-6
The thousands place is <u /><em></em>the 9 in 39<u>9</u>,713. 7 is closer to 10 than to 0, therefore, you roundup, increasing the thousands place by one. Carry the 0 to the next 9 in the ten thousands place, and again to the hundred thousands, adding one to the 3. Therefore the answer is 400,000.<u />
