The sum of the coordinates of the point is 7.25
The reason the above values are correct is as follows;
The given parameter is;
The point (9, 7) is on the graph y = f(x)
Required:
A point on the graph, 2·y = (f(2·x)/2) + 2
Solution:
Let x = 9/2, given that (9, 7), is on the graph, f(x), we get;
f(2·x) = f(2 × 9/2) = f(9) = 7
Therefore;
2·y = (f(2·x)/2) + 2 = (7/2) + 2) = 5.5
y = 5.5/2 = 2.75
y = 2.75
The coordinate of the point is (x, y) = (2.75, 9/2)
The sum of the coordinates of the point is 2.75 + 9/2 = 7.25

What is the constant of proportionality that relates y , the total cost in dollars, to x , the number of tickets purchased?
PLZ I HAVE TO FINISH THIS TEST TODAYYY
Answer:
4 tickets for $1
Step-by-step explanation:
I just divided 8 with 2.00 and got 4.
The value of the constant of proportionality that relates y, the total cost in dollars, to x, the number of tickets purchased is 1/4.
What is a proportional relationship?It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
It is given that:
At a school carnival, tickets can be purchased to participate in different activities.
The data are shown in the picture.
From the data:
y ∝ x
Removing the proportional sign:
y = kx
Plug x = 8
y = 2
2 = 8k
k = 1/4
Thus, the value of the constant of proportionality that relates y, the total cost in dollars, to x, the number of tickets purchased is 1/4.

In which equation would you multiply both sides by 4.5 to get the variable alone?
A.6.1p = 4.5
B.p ÷ 6.1 = 4.5
C.p ÷ 4.5 = 6.1
D.4.5p = 6.1
By applying the multiplication property, the equation you would multiply both sides by 4.5 to get the variable p alone is: C. p ÷ 4.5 = 6.1
Recall:
When applying the multiplication property of equality to find a variable, both sides of the equation will be multiplied by the same term/value.Therefore, for the equation p ÷ 4.5 = 6.1, which is:
p/4.5 = 6.1
To get the variable p alone, multiply both sides by 4.5
Thus:p/4.5 × 4.5 = 6.1 × 4.5
p = 27.45
Therefore, by applying the multiplication property, the equation you would multiply both sides by 4.5 to get the variable p alone is: C. p ÷ 4.5 = 6.1

11) slope and y-intercept, if the answer ignore this if you do know the answer than plz answer
Answer:
Slope : -1
Y-intercept : (0,6)
Step-by-step explanation:
Answer:
Slope: -1
y-intercept: 6
Step-by-step explanation:
Lets figure out the slope with the formula, [tex]\frac{y2 - y1}{x2-x1}[/tex]. Take 2 coordinates and substitute them in. Lets take (-3,9) and (-1,7). Here are the steps:
[tex]\frac{7-9}{-1-(-3)}[/tex]
[tex]\frac{-2}{-1+3}[/tex]
[tex]\frac{-2}{2}[/tex]
[tex]-1[/tex]
Now we know that the slope is -1, so m = -1.
Lets figure out the y-intercept. We have to have an equation with the slope in it. Since we don't know the y-intercept yet, we will use the equation y = -x + b. Lets take the coordinate (5,1). Substitute the coordinates in. Here are the steps:
1 = -5 + b
b = 6
Now we know that the y-intercept is 6, so b = 6. I hope this helped!

The profit y(in dollars) for a business from selling x coats is represented by y=47x . Graph the equation.
The graph of the equation is attached .
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
The slope-intercept form of the line equation
y= mx + c
where m is the slope
b is the y-intercept
We are Given that the profit y (in dollars) for a business from selling x coats is represented by the equation
y=47x .
Now comparing with the slope-intercept form of the line equation;
m = 47
We know that the value of the y-intercept can be determined by setting x = 0
substitute x = 0 in the equation
y = 47(0)
y = 0
Thus, the y-intercept b = 1
Thus,
The slope m = 47
The y-intercept b = 1
The graph of the equation is also attached.

9. The two figures below have a scale factor of 3 : 2. What is the value of x?
The value of x can be found by setting up a proportion based on the given scale factor of 3:2 is 16/3 units.
The breadth of the first parallelogram is 8 and the breadth of the second parallelogram is x.
Setting up the proportion, gives:
8/3 = x/2.
To solve for x, cross-multiply:
[tex]8 \times 2 = 3 \times x.[/tex]
Simplifying the equation, gives:
16 = 3x.
Next, divide both sides of the equation by 3 to isolate x:
x = 16/3.
Therefore, the value of x is 16/3.
