Answer:
18x+9=9y
Step-by-step explanation:
16x+9=9y-2x
+2x +2x
18x+9=9y
5 + 6 − 1 2 − 1 1 -11y 5+6y−12−11y − 7 + 6 − 1 1
− 7 + 6 − 1 1 −7+6y−11y − 7 − 5
− 7 − 5 −7−5y − 5 − 7
Solution: −5y−7
Answer:
20
Step-by-step explanation:
Sn = (n/2)(a1 + a1 + d(n-1)), where S = sum, a1 = first term, n = number of terms, d = common difference
400 = (n/2)(1 + 1 + 2(n - 1))
400 = (n/2)(2 + 2n - 2)
400 = (n/2)(2n
400 = n2
20 = n
Twenty numbers are in the set.
A) -2.8 > -3.5 is true. There are infinite solutions.
B) -7.75 < -8.45 is false. There is no solution.
C) 6.52 < 6.5 is is false. There is no solution.
D) -11.1 > 10.7 is false. There is no solution.
1. V = x (12 - 2x) (8 - 2x)
The zeros are 0, 6, and 4
2. dV/dx = x(12 - 2x)(-2) + (8 - 2x)(12-4x) = 0
x = 4.9
3. If V = 12 = x (12 - 2x) (8 - 2x)
x = 0.13, 3.65, 6.22
4. If we increase the dimensions of the cutout until 4.9, the volume will also increase, after that, the volume will decrease.
5. V = x (q - 2x) (p - 2x)
