Does the table below represent a function?
A table titled 'Car Wash Grand Opening' is shown. The first column, 'Time comma x left parenthesis minutes right parenthesis' contains the values 0 through 3 in order top to bottom. The second column 'Water comma y left parenthesis gallons right parenthesis' has the values 440, 428, 416, and 404 listed top to bottom.
A. yes
B. no
I will mark brainliest for step by step process and correct solution. Thanks! Need this ASAP!
Answer:
a) Yes.
Step-by-step explanation:
A function does not have any repeating values for a given x-value. According to the values of the table, there aren't multiple y-values for a given x-value. Therefore, the table represents a function.
state the angle pair relationship then find the value of x
Answer:
x = 11
Step-by-step explanation:
The given angles are corresponding angles and are congruent, then
12x - 9 = 10x + 13 ( subtract 10x from both sides )
2x - 9 = 13 ( add 9 to both sides )
2x = 22 ( divide both sides by 2 )
x = 11

Step-by-step explanation:
Which of the following transformations does not
preserve congruence?
F. (x,y) → (-x, -Y)
G. (x, y) = (-y, -x)
H. (x, y) = (x + 9.y + 9)
J. (x,y) → (9x, 9y)
Answer:
(9x, 9y) dilation
Step-by-step explanation:
(9, 9y) is the answer because F is 180 degrees rotations, G is not real, H is translations, and J is dilations and dilations is multiplying which makes the transformation non congruent.

If line segment AB,A(9,3) and B(-6,-9), what scale factor was used to dilate if new line is at A'(3,1) and B'(-2,-3)?
Answer:
The scale factor is 1/3
Step-by-step explanation:
Here, we want to get the scale factor used in dilating the original segment
As we can see;
(9,3) turned to (3,1)
looking at this , we can see that both coordinate values were divided by 3
So what this mean is that the particular scale factor used is reduction by 1/3
This is the case with the other point as (-6,-9) turned to (-2,-3)
The ratio of two numbers is 8: 5. Their sum is 91. What is the
greater number?
Answer:
Step-by-step explanation:
a:b = 8:5
a = 8x, b= 5x
a+b = 91
13x = 91
x = 7
a=8x = 56
b = 5x = 35
The larger number is 56
Placed the following quadratic in vertex form by completing the square and then state the coordinates of its vertex?
Y=x^2+18x-12
Answer:
y = (x + 9)² -93
vertex: (-9, -93)
Step-by-step explanation:
x² + 18x = 12
x² + 18x + 81 = 12 + 81
(x+9)² = 93
y = (x + 9)² -93
vertex: (-9, -93)

Ann runs a day care center. Of the last 18 children to enroll at the day care center, 8 of them have been elementary school students. Considering this data, how many of the next 9 children to enroll should you expect to be elementary school students?
We would expect that 4 of the next 9 children to enroll will be elementary school students.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If 8 out of the last 18 children to enroll at the daycare center were elementary school students,
We can find the fraction of elementary school students in that group by dividing the number of elementary school students by the total number of children:
= 8/18
= 4/9
This means that 4 out of every 9 children enrolled were elementary school students.
If we want to predict how many of the next 9 children to enroll will be elementary school students,
We can use this ratio:
4/9 of 9 children
= (4/9) x 9
= 4
Therefore,
We would expect that 4 of the next 9 children to enroll will be elementary school students.

Answer:
x=52
Step-by-step explanation:
vertical angles are congruent so that means the angle measures are the same
so, you can set up this equation:
156=3x
and solve as follows:
156=3x
/3 /3
52=x
To prove that x=52 you can input 52 as x in the equation
156=3(52)
156=156

Answer:
1200 square inches
Step-by-step explanation:
First find area of rectangle which is length x width
20 x 30 = 600
then to find area of the two right triangles multiply the legs then divide by 2
20 x 30 = 600
600/2 = 300
since there is 2 multiply 300 by 2
600
then add everything together
600+600 = 1200
What is the solution to the system of equation of 2x+3y=6 and x-3y=9
Answer:
x = 5
y = -4/3
Step-by-step explanation:
Solve by elimination by adding the two equations together:
2x + 3y = 6
x - 3y = 9
3y and -3y will cancel out. Then, solve for x:
3x = 15
x = 5
Plug in 5 as x into one of the equations, then solve for x:
x - 3y = 9
5 - 3y = 9
-3y = 4
y = -4/3
So, the answer is x = 5 and y = -4/3
The eastbound train travels 10 miles per hour faster than the westbound train. After 2 hours, they are 232 miles apart. At what speeds are the two trains traveling?
Answer:
48,58
Step-by-step explanation:
Let The speed of the west bound train be x
Let the east bound train be x+10
The speeds can be calculated as follows
2(2x+10)= 232
4x + 40= 232
4x= 232-40
4x= 192
x= 192/4
= 48
Hence the speedof the west bound train is 48
The speed of the east bound train is 48+10
= 58

y = -2x + 3
in the equation y = mx + b, the m represents the slope and b represents the y-intercept
remember that slope is rise over run:
starting from the point (1, 1) you rise 2 up and go over left 1 to reach the second point shown (0, 3).
add a negative sign to show the negative downward slope, and the m in the equation would be -2
the y-intercept is just where the line hits the y-axis, or when the x in the ordered pair is 0. In this graph, one of the points given is (0, 3) so 3 is the y intercept
just plug all that into y = mx + b
m, the slope, is -2 and b, the y- intercept, is 3.
y = -2x + 3 is your answer
7) Celia is scheduled to work a total of 20 hours this week. So far she has worked 75% of her hours. How many hours has she worked so far this week? *
Answer:
Number of hours she worked so far = 15 hours
Step-by-step explanation:
Total hours scheduled to work this week = 20 hours
Percentage of Hours worked so far = 75%
How many hours has she worked so far this week?
Number of hours she worked so far = 75% of 20 hours
= 75/100 * 20
= 0.75 * 20
= 15
Number of hours she worked so far = 15 hours
A store offers a discount of 40%. The discount price of a shirt is $42 . What is the regular price?
Answer:
$70 is the regular price of the shirt.
Step-by-step explanation:
One way in which to find the regular price here is to write the equation
0.60s = $42. A 40% discount is reflected in 100% - 40%, or 1.00 - 0.40, which comes out to 0.60.
If 0.60s = $42, then the regular price of the shirt is
s = ($42)/0.60 = $70

$70.00

Which of the following functions is equivalent to the function below?
Select three that apply.
f(x)=(13)2x
g(x)=(23)−x
g(x)=9−x
g(x)=3x2
g(x)=(16)x
g(x)=(19)x
g(x)=3−2x
Answer:
g(x) = 3x2
g(x) = 16x
g(x) = 19x
Explanation:
Assuming that you're referring to f(x) = (13)2x, without much context, I'm going to assume that any of the ax + b, are going to be wrong. The the process of elimination, the only ones left are just x and a coefficient.
Hope that helps!
