Which of the tables represents a function?
Table A
Input: 4, 5, 4,
Output: 2,9,7,
Table B
Input: 9,9,7,
Output: 2,3,5,
Table C
Input: 4,6,2,
Output: 3,5,7,
Table D
Input: 8,6,8,
Output: 7,5,5,
A) Table A
B) Table B
C) Table C
D) Table D
With tables A, B and D, we have repeated input (x) values.
Table A has x = 4 repeated. So the input x = 4 leads to both outputs y = 2 and y = 7 at the same time. With any function, we must have exactly one and only one output for any given input. So this is why table A is not a function. Tables B and D are not functions for similar reasons.
Table C on the other hand has unique inputs that do not repeat. The input x = 4 only leads to y = 3, x = 6 pairs with y = 5, and x = 2 outputs to y = 7. Therefore we have a function here.
students enter school in the morning through doors on opposite sides of cafeteria. At Ms. Logrieco's door,35 students enter in the first 10 minutes. At Mr. Riley's door,22 students enter in the first 8 mins. If students continue to arrive at school at the same rate,how many students do you expect to be in the cafeteria after 24 minutes?
Ms. Logrieco's door: 35 students per 10 minutes
Mr. Riley's door: 22 students per 8 minutes
Time Frame: 24 minutes
35 x 2 = 70
35 x 2/5 = 14
70 + 14 = 84
22 x 3 = 66
84 + 66 = 150
Thus, we can expect for 150 students to be in the cafeteria after 24 minutes.

B. No, because it is not a straight line.
O C. Yes, because it is a curved line.
D. Yes, because it passes the vertical line test.

Ask yourself if it is possible to draw a single straight line through more than one point on the red curve. If it is possible, then the graph is said to fail the vertical line test. Otherwise, the graph passes the test.
In terms of algebra, any input x value leads to one and only one y output value. This is what defines a function. If you had x lead to more than one output, then we wouldn't have a function. Of course, the x value must be in the domain.

what is a measure ∠x
Answer:
x = 138
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles
x = B+ C
x = 68+ 70
x =138
Answer:
138 degrees
Step-by-step explanation:
A triangle is made up of 180 degrees, it lists 2 values already, 68&70. when added that equals 138.
So 180-138 is 42 degrees, which would be the last angle within the triangle.
Since a line is also 180 degrees, its 180-42, which makes x 138 degrees
As part of their fundraising for Right To Play, the student council is having a fun-fair at lunch in the schoolyard. You will be running three events at different locations: a basketball foul-shot contest, a mini-putt course, and a dunk-tank. Your job is to locate the ticket booth so that it will be the same distance from each of the events. Describe the process you would use to determine the position of the ticket booth. Create a GeoGebra design that supports your decision.
Answer: see below
Step-by-step explanation:
I used a coordinate graph and placed the Ticket Booth at the origin (0, 0)
Then I chose a distance of 4 (you can choose any distance) and placed the three events equidistant from the origin by using the x- and y- axis to easily determine a distance of 4 from the origin.
(0 - 4, 0) = (-4, 0)
(0 + 4, 0) = (4, 0)
(0, 0 + 4) = (0, 4)
If the booths are placed first you would need to find the equation of a circle that contains all three points and place the booth at the center.
You do this by creating a system of three equations inputting the x,y coordinates of each booth and solving for h, k, r.
Equation of a circle is: (x - h)² + (y - k)² = r²
Calculate the amount of paint needed to cover the following door:
Note: You do not paint the window on the inside.
Answer:
Step-by-step explanation:
The door is shape is a combination of a rectangle and a semicircle with a square window.
Area of the door = Area of rectangle + area of a semi circle
Area of a rectangle = Length * Width (LW)
area of a semicircle = πr²/2 where r is the radius of the semi circle.
Given the length of the rectangle = 2m and its width = 1m
Area of rectangle = 2*1 = 2m²
Given the radius of the semicircle = 1/2 m
Area of the semi circle = π(0.5)²/2
= 0.25π/2
= 0.785/2
Area of the semicircle= 0.3925m²
Area of the door = 2+0.3925
Area of the door = 2.3925m²
Since we are not to paint the window, we will subtract the area of the window from the total area.
Area of the window = area of a square = 0.2*0.2
= 0.04m²
Area to be painted = Area of door - Area of the square
Area to be painted = 2.3925m² - 0.04m²
Area to be painted = 2.3535m²
Note that there was no enough information for us to calculate the amount of paint needed but knowing the area of the part to be painted can guide us.

Answer:
(2,-1)
Step-by-step explanation:
Welol to find the line of (3,7) and (2,-1) we need to use the following formula,
[tex]\frac{y^2-y^1}{x^2-x^1}[/tex]
So -1 is y2 7 is y1 so -1 - 7 = -8
2-3 = -1
Hence, the slope of the line is 8.
And graphing more points on the graph using the slope we can see the y intercept is -17.
So the equation is y = 8x - 17
And the mid point is at (2, -1)
9) Arthur weighs 54 lbs. more than Lily. Their combined weight is 280 lbs. less than 6 times Lily’s weight. How much does Arthur weigh?
Answer:
137.5 lbs.
Step-by-step explanation:
Arthur = 54 + x
Lily = x
Arthur + Lily = 6x - 280
(54 + x) + x = 6x - 280
54 + x + x = 6x - 280
54 + 2x = 6x - 280
54 = 4x - 280
334 = 4x
83.5 = x
Arthur = 54 + x
Arthur = 54 + 83.5
Arthur = 137.5
Instructions: Find the angle measures given the figure is a rhombus.

Answer:
about 325
Step-by-step explanation:
On average, the mileage is about 21.7 miles per gallon, so 15 gallons would be good for about 325 miles.
If we look at the table for fills that total 15 gallons, we see the first and last total 330 miles, and the 3rd and 4th total 314 miles. So, we expect somewhere between these values, on average.
A formal average adds the miles driven and divides by the total of gallons used. That result is shown below. While we might estimate that we could drive 325 miles on 15 gallons, we have found that our mileage actually varies.
Determine the intercepts of the line.
y = -2x – 21
c-intercept:
y-intercept:
Answer:
x-intercept = -6
y-intercept = -21Step-by-step explanation:
x - intercept is for y = 0
y - intercept is for x = 0.
We have y = -2x - 21.
Substitute:
x = 0 → y = -2(0) - 12 = 0 - 12 = -12
y = 0 → 0 = -2x - 12 add 2x to both sides
2x = -12 divide both sides by 2
x = -6

Find the value of x in the triangle
shown below.
X
85
67
Answer:
28
Step-by-step explanation:
All angle measures must add up to 180. x + 85 + 67 = 180; x = 28
For any triangle, the three angles always add to 180 degrees
85+67+x = 180
x+152 = 180
x = 180-152
x = 28

Step-by-step explanation:
You have the following equation:
[tex]\frac{6}{x}-\frac{4}{5}=\frac{2x}{5}[/tex] (1)
To find the solutions of the equation (1) you first eliminate the denominators of the equation, by multiplying the m.c.m, which is 5x, as follow:
[tex]30-4x=2x^2[/tex]
Next, you write the previous equation in the general form ax^2 +bx+c=0, as follow:
[tex]2x^2+4x-30=0[/tex]
Next, you use the quadratic formula to find the solutions:
[tex]x_{1,2}=\frac{-b\pm \sqrt{b^2-4(a)(c)}}{2a}\\\\a=2;\ \ b=4;\ \ c=-30\\\\x_{1,2}=\frac{-4\pm \sqrt{4^2-4(2)(-30)}}{2(2)}\\\\x_{1,2}=\frac{-4\pm16}{4}\\\\x_1=-5\\\\x_2=3[/tex]
Then, the solutions for the given equation are x1=-5 and x2=3

An entertainment services provider on the internet has 10000 subscribers paying $15 per month. It can get 1000 more subscribers for each $1 decrease in the monthly fee. Determine the monthly fee that will yield the maximum monthly revenue and the value of that revenue
Answer:
Monthly fee that will yield the maximum monthly revenue is $12.5
Then the value of the maximum monthly revenue is $156 250
Step-by-step explanation:
x - value of decrease
1000x - number of new subscribers for $x decrease
10000+1000x - number of subscribers after $x decrease in the monthly fee
15-1x the monthly fee after $x decrease
f(x) = (10000 + 1000x)(15 - x) ← quadratic function
For quadratic function given in standard form: f(x) =a(x-h)²+k where a<0 the f(x)=k is the maximum value of function, and occurs for x=h
[tex]h=\frac{-b}{2a}\ ,\quad k=f(h)[/tex]
Expressing given function to standard form:
f(x) = 1000(10 + x)(15 - x)
f(x) = 1000(150 - 10x + 15x - x²)
f(x) = 1000(-x² + 5x + 150)

Find the coordinates of point BBB on \overline{AC}
AC
start overline, A, C, end overline such that the ratio of ABABA, B to BCBCB, C is 2:12:12, colon, 1.
Answer:
The coordinates of point B are (-2, 2).
Step-by-step explanation:
Given:
Point A (2,−8)
Point C (−4,7)
Point B divides the line AB such that the ratio AB:BC is 2:1.
To find: The coordinates of point B.
Solution:
We can use the segment formula here to find the coordinates of point B which divides line AC in ratio 2:1
[tex]x = \dfrac{mx_{2}+nx_{1}}{m+n}\\y = \dfrac{my_{2}+ny_{1}}{m+n}[/tex]
Where [tex](x,y)[/tex] is the co-ordinate of the point which
divides the line segment joining the points [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] in the ratio [tex]m:n[/tex].
m = 2
n = 1
As per the given values
[tex]x_{1} = 2\\x_{2} = -4\\y_{1} = 8\\y_{2} = 7[/tex]
Putting the values in the formula:
[tex]x = \dfrac{2 \times (-4)+1\times 2}{2+1}=\dfrac{-8+2}{3} =-2\\y = \dfrac{2\times 7+1 \times (-8)}{2+1} = \dfrac{6}{3} =2[/tex]
So, the coordinates of point B are (-2, 2).
solve the systems by the addition method x - 2y = - 4 2x + y = 7
To solve this system of equations by addition, our first goal is to cancel
out one of the variables by adding the two equations together.
However, if we add these two equations together right away, nothing
will cancel so we need to set things up so a variable will cancel.
Notice that we have an 2x in our second equation.
If we had a -2x in our first equation, then the x's would cancel out.
In order to create a -2x in the first equation, we simply
multiply both sides of the first equation by -2.
So we have (-2)(x - 2y) = (-4)(-2) which can be rewritten as -2x + 4y = 8.
Now rewrite both equations, as shown below.
-2x + 4y = 82x + y = 7Now when we add the equations together, the x terms
will cancel out and we're left with 5y = 15.
Dividing both sides by 5, y = 3.
To solve for x, plug a 3 in for y in either one of our 2 original equations.
So let's go with our second equation.
Plugging a 3 in for y, we get 2x + (3) = 7.
Now subtract 4 from both sides to get 2x = 4.
Dividing both sides by 2, we fid that x = 2.
Since x = 2 and y = 3, our answer is the ordered pair (2, 3).
In solving the formula
A = (1/2)bh, in solving for h, you could first multiply both side by 1/2.
