2(x + 11) + 7x = 9x - 22
mutiply the bracket by 2
(2)(x)= 2x
(2)(11)= 22
2x+22+7x=9x-22
2x+7x+22= 9x-22 ( combine like terms)
9x+22= 9x-22
move 9x to the left side
sign changes from +9x to -9x
9x-9x+22= 9x-9x-22
0+22= 0-22
22= -22
Answer:
C. no real solutions
The answer is 17.9 in. mean snowfall over a 10-year period.
y = (x-6)²-3
1) Let's write a transformation described as it is, algebraically speaking.
• opening upward, (a >0)
,
• shifted 6 units right, (-6)
,
• and three units down -3
2) Starting from the parent function y=x², then we can write:
y = (x-6)²-3
Notice that the horizontal shift is within the parentheses with a swapped sign. And outside that -3 indicating the vertical shift.

Step-by-step explanation:
Multiply 5x4.49= 22.45
Do the same for the gasoline G5x2.59= 12.95
T22.45+12.95= 35.40
Assuming that the pool is a perfect rectangular prism, then its volume, V, is given by
, where l is the length, w is the width, and h is the height. Manipulate this formula first to solve for length.
Divide both sides of the equation by w*h.
Now, plug in your values for volume, width, and height.
The answer is 120 ft.
