Choice A) The vertical line test confirms that the graph is a function
True. It is impossible to pass a single vertical line through more than one point on this graph.
--------------------------------------------
Choice B) The domain is x >= 2
False. The domain is the set of all real numbers
--------------------------------------------
Choice C) The range is y >= 2
True. The smallest y value possible is y = 2. This is where the lowest part of the graph occurs.
--------------------------------------------
Choice D) This piecewise function is made up of four intervals
False. There are two intervals (the curved one on the left; the straight piece on the right)
--------------------------------------------
Choice E) Each interval of the piecewise function contains a graph of a linear function.
False. While the piece on the right is linear, the left portion is nonlinear (curved piece).
--------------------------------------------
In summary we have:
choice A) true
choice B) false
choice C) true
choice D) false
choice E) false
So the answers are choice A and choice C
0.25x + 0.10y = 0.15*15
X + Y = 15
Y = 15 - X
0.25X + 0.10(15 - X) = 2.25
0.25X + 1.5 - 0.10X = 2.25
.15X = 0.75
X = 5
Y = 15 - 5
Y = 10
9(3x - 16) + 15 = 6x - 24
First distribute 9 to 3x and -16.
27x - 144 + 15 = 6x - 24
Combine like terms. (-144 + 15)
27x - 129 = 6x - 24
Get the variable, x, on one side of the equation. You can do this by subtracting 6x from both sides.
21x - 129 = -24
Add 129 to both sides to isolate x.
21x = 105
Divide 21 off of both sides to find the value of x.
x = 5
You can plug x into the equation to check your answer.
9(3 x 5 - 16) + 15 = 6(5) - 24
6 = 6
Answer:
c 0.269
Step-by-step explanation:
2x3=6 2x6=18 3x6=24 so its non repeating here i bless the eyes
201.062, the formula is A=3.14r^2, 8 is your r and then you square it making it 64, then multiply 64 by 3.14 or pi and get 201.06
