Explanation:
Both points have the same x coordinate, which immediately tells us both points are on the same vertical line.
All vertical lines have an undefined slope. This is because when it comes to rise/run, the "run" is zero. Dividing by zero is not allowed.
Check out the steps below.
[tex](x_1,y_1) = (-10,9) \text{ and } (x_2,y_2) = (-10,18)\\\\m = \text{slope} = \frac{\text{rise}}{\text{run}} = \frac{\text{change in y}}{\text{change in x}}\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{18 - 9}{-10 - (-10)}\\\\m = \frac{18 - 9}{-10 + 10}\\\\m = \frac{9}{0}\\\\m = \text{UND}\\\\[/tex]
The "UND" is shorthand for "undefined". Some textbooks may use the notation "NaN" to refer to "not a number".

Step-by-step explanation:
The graph represents function 1, and the equation represents function 2: A coordinate plane graph is shown. A horizontal line is graphed passing through the y-axis at y = 6. Function 2 y = 2x + 7 How much more is the rate of change of function 2 than the rate of change of function 1? (4 points) a 1 b 2 c 3 d 4
The rate of change of function 2 is greater than the rate of change (slope) of function 1 by: B. 2.
How to determine the difference in the rate of change?Since the line on this graph is perpendicular to the y-axis (horizontal line), we can reasonably and logically deduce that its rate of change (slope) is equal to zero (0) because there is no change in the y-value on the y-axis.
This ultimately implies that, the rate of change (slope) of function 1 (y = 6) with an horizontal line is equal to zero (0).
Next, we would calculate the rate of change (slope) of function 2 i.e y = 2x + 7. Mathematically, the standard form of the equation of a straight line function is given by;
y = mx + c
Where:
m represents the slope.x and y are the points.c represents the y-intercept.By comparing the two (2) equations, we have the following:
y = mx + c ≡ y = 2x + 7
Therefore, the rate of change (slope) of function 2 is equal to 2.
Now, we can calculate the difference between the rate of change (slope) of function 2 and the rate of change (slope) of function 1 as follows:
Difference = 2 - 0
Difference = 2.

The cost in dollars of making x items is given by the function C(x)=10x+900 .
a. The fixed cost is determined when zero items are produced. Find the fixed cost for this item.
Fixed cost =$
b. What is the cost of making 25 items?
C(25)=$
c. Suppose the maximum cost allowed is $1900 . What are the domain and range of the cost function, C(x) ?
Domain:
Range:
Step-by-step explanation:
when we give a function an actual value as argument, we are using the variable(s) in the functional definition as intended : as placeholders for actual values.
so, we only need to replace any occurrence of the variable by the actual value and calculate.
a.
zero items are produced means x = 0.
C(0) = 10×0 + 900 = $900
fixed cost = $900
b.
making 25 items means x = 25.
C(25) = 10×25 + 900 = 250 + 900 = $1,150
c.
the domain is the interval or set of all valid values for x.
the range is the interval or set of all valid values for y (the functional result).
now, the maximum cost allowed is $1900.
how many items are that ?
1900 = 10x + 900
1000 = 10x
x = 100
so, the domain is
0 <= x <= 100
the range is
$900 <= y <= $1900
The annual fundraising goal of a is $100,000. So far $46,088 has been raised. How much more money is needed to reach the goal? What???
If annual fundraising goal of a is $100,000 and so far $46,088 has been raised, then they have to raise $53912 to reach the goal
The goal of the annual fund raising = $100000
The raised amount = $46088
The amount of money needed to reach the goal = The goal of the annual fund raising - The raised amount
Here we have to use the subtraction
Substitute the values in the equation
The amount of money needed to reach the goal = 100000 - 46088
= $53912
Hence, if annual fundraising goal of a is $100,000 and so far $46,088 has been raised, then they have to raise $53912 to reach the goal

Step-by-step explanation:
c = 2a;
b = 2d;
c + 2d = a + 2b
2a + b = a + 2b
a = b
a = b
c = 2a
d = b/2
Assume a = 100.
b = 100
c = 200
d = 50
This cannot be, but we can continue.
Add them: 100 + 100 + 200 + 50 = 450
The total must be an even multiple of 450.
The total can be 900, 1800, 2700, etc.

4) x+y-4=0
2x-3y-3=0
By solving these two equations we get,
x=3 and y=1
(x, y)=(3,1)
Consequently, there is only one solution to the linear system.
5) 5x-y-5=0
5x-y-15=0
a₁/a₂=1
b₁/b₂=1
c₁/c₂=1/3
∴ a₁/a₂=b₁/b₂≠c₁/c₂

15. Todd purchased two CDs and three cassette tapes for $75. Paulena went to the same
music store and purchased one CD and five cassette tapes for $76. If all CDs are the
same price and all the cassette tapes are the same price, find the cost of each CD and
each cassette tape.
The cost of each CD is $21 and the cost of each cassette tape is $11.
According to the question,
We have the following information:
Todd purchased two CDs and three cassette tapes for $75. Paulena went to the same music store and purchased one CD and five cassette tapes for $76.
Now, let's take the cost of each CD to be $x and the cost of each cassette tape to be $y.
So, we have the following expressions:
2x+3y = 75 ..(1)
x+5y = 76
x = 76-5y ..(2)
Putting the value of x in equation 1:
2(76-5y)+3y = 75
152-10y+3y = 75
152-7y = 75
Subtracting 152 from both sides:
-7y = 75-152
-7y = -77
y = 77/7
y = $11
Putting this value in equation 2:
x = 76-5y
x = 76-5*11
x = 76-55
x = $21
Hence, the cost of each CD is $21 and the cost of each cassette tape is $11.
