Place a pencil vertically on the paper, and move it left to right or vise-versa
When moving it make sure the pencil doesn't hit two points at once if it does it is not a function, but this is not the case
This is a function
In this situation, we would use something called the vertical line test. In other words, if we can draw a vertical line that passes more than one point on the graph, then the relation is not a function.
If we use the vertical line test in this situation, it is not possible to draw a vertical line that passes through more than one point. Therefore, this does represent a function.

Graph the system of equations. {2x−y=4x−y=−2 Use the Line tool to graph the lines.
Answers
Hear hear! For I have brought you the correct answer... (I took a "snip" of it so you can't see the entire graph but you can see the whole answer.)
By plotting the lines 2x - y = 4 and x - y = -2 using a graphing tool or on graph paper.
To graph these lines, you can start by rearranging them into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.
For 2x - y = 4:
-y = -2x + 4
y = 2x - 4
This equation has a slope of 2 and a y-intercept of -4.
For x - y = -2:
-y = -x - 2
y = x + 2
This equation has a slope of 1 and a y-intercept of 2.
Now, you can graph these lines on a coordinate plane by plotting the y-intercepts and using the slopes to find additional points.
Once you have the two lines graphed, their point of intersection represents the solution to the system of equations.

Sergei says that 10% of a number will always be less than 20% of any other number.
Answers
This isn't true, because if you were to take 10% of, let's say, 100 (which is 10), and if you were to take 20% of 20 (which is 5), 5 is still smaller than 10.

Answers
y = 10x - 5
Explanation:
The equation of the line has the general formula:
y = mx + c
where:
m is the slope = 10
c is the y-intercept = -5
Substitute with the givens in the above formula to get the equation as follows:
y = mx + c
y = 10x + (-5)
y = 10x - 5

Chris needs 3 1/2 cups of flour. His only clean measuring cup holds 1/3 cup. how many 1/3 cups of flour does Chris need?
Answers
To find the number of 1/3 cups of flour Chris needs, we need to divide the total amount of flour needed by the amount that can be measured with the 1/3 cup measuring cup. In this case, Chris needs 28 1/2 cups of flour.
Explanation:To find the number of 1/3 cups of flour Chris needs, we need to divide the total amount of flour needed (3 1/2 cups) by the amount that can be measured with the 1/3 cup measuring cup.
To do this, we convert the whole number 3 to thirds by multiplying by 3, which gives us 9 thirds. Then we add the 1/2 cup, which is equivalent to 3/6 or 6/12. So, the total amount in thirds is 9 + 6/12 = 9 1/2 thirds.
Now, we divide the total number of thirds by the number of thirds in one 1/3 cup.
9 1/2 thirds ÷ 1/3 third/cup = (9 1/2) ÷ (1/3) = (19/2) ÷ (1/3) = 19/2 × 3/1 = 19/2 × 3/1 = 57/2 = 28 1/2 cups.

A salesperson receives a 3% commission on sales. The salesperson receives $180 in commission. What is the amount of sales?
Answers
180/x = 3/100
We do this, because 180 is part of the whole, 3% is a part of 100%. This proportion will help us get to the correct answer. Let's cross multiply. 180 * 100 is 18,000. 3 * x is 3x. that makes 18,000 = 3x. Now, divide each side by 3 to isolate the x. 3x/3 cancels out. 18,000/3 is 6,000. Let's check this. 6,000 * 3% (0.030 is 180. 180 = 180. There. x = 6,000. The amount of sales is $6,000.

Please find x: 3x − 1 = 2x − 1
Answers
3x - 1 = 2x - 1
Start by subtracting 2x on both sides
3x - 1 - 2x = 2x - 1 - 2x
x - 1 = - 1
Then add 1 on both sides
x - 1 + 1 = -1 + 1
x = 0
I hope this helps!
As always, it is my pleasure to help students like you.
======================================================================
SOLVING.....
3x − 1 = 2x − 1
Subtract 2x from each side
3x − 1 − 2x = 2x − 1 − 2x
x − 1 = −1
Add 1 to each side
x − 1 + 1 = −1 + 1
x = 0
====================================================================
CHECKING.....
Substitute 0 for x in 3x − 1 = 2x − 1
3(0) − 1 = 2(0) − 1
0 - 1 = 0 - 1
-1 = -1
This is true so x does equal 0
Explain how you can determine that the following system has one unique solution – without actually solving the system. 2x+y=4 , 2y=6-2x
Answers
To compare the lines put them both in slope intercept form. The first equation will be y = -2x + 4 and the second equation will be y = -1x + 6. The slopes of the 2 graphs are different. These means that they are going in different directions. Therefore, they will cross a one unique point.
Answer:
Both equations has different slope , so the system of equation have one unique solution.
Step-by-step explanation:
[tex]2x+y=4[/tex] , [tex]2y=6-2x[/tex]
To determine that the system of equation has unique solution, we need to find out the slope.
To find slope, we write the equation in the form of y=mx+b
Where m is the slope and b is the y intercept
[tex]2x+y=4[/tex]
Subtract 2x on both sides
[tex]y=-2x+4[/tex]
here, m= -2 is the slope
[tex]2y=6-2x[/tex]
Divide both sides by 2
[tex]y=3-x[/tex]
[tex]y=-x+3[/tex]
Slope m = -1
Both equations has different slope , so the system of equation have one unique solution.

The top and bottom areas of the base cuboid are (10 in)*(10 in) = 100 in^2, for a total of 2*100 in^2 = 200 in^2.
The lateral area of the base cuboid is its perimeter (4*10 in = 40 in) multiplied by its height (2 in), so is 80 in^2.
Likewise, the lateral area of the "tower" is the product of its perimeter (4*5 in = 20 in) and its height (8 in), so is 160 in^2.
The sum of all these is 200 in^2 +80 in^2 +160 in^2 = 440 in^2.

A school baseball team earned $3416.90 from selling 5716 tickets to their game. If grandstand tickets sold for 65 cents each and bleacher tickets sold for 40 cents each, how many of the bleacher tickets were sold?
Answers
Let x and y represent the number of grandstand and bleacher tickets sold respectively.
We know that the total number of tickets sold is 5716. Therefore, we will get the equation:
x+y = 5716
Therefore, x=5716-y.............................(Equation 1)
Now, we also know that the total value of tickets sold is $3416.90 or 341690 Cents.
We also know that the price of one grandstand ticket is 65 Cents. Thus, the price of x grandstand tickets will be 65x cents.
Likewise, since the price of one bleacher ticket is 40 cents, the price of y bleacher tickets will be 40y cents.
The information presented above gives us:
65x+40y=341690..........................(Equation 2)
Substituting x from (Equation 1) to (Equation 2) we get:
[tex] 65(5716-y)+40y=341690 [/tex]
Let us solve the above equation for y.
[tex] 65\times 5716-65y+40y=341690 [/tex]
[tex] 371540-25y=341690 [/tex]
[tex] \therefore 25y=371540-341690=29850 [/tex]
[tex] y=1194 [/tex]
Therefore, the total number of bleacher tickets sold was 1194.

Because if you rearrange all the letters so that W is is the beginning you get 6 different combinations.
Then I multiplied those 6 combinations by 4 because there are 4 letters.
Once I multiplied I got 2/24 because there are 24 possibilities in total, and we are looking for the probability of getting those 2 combinations.
I simplified 2/24 to its lowest form and I got 2/24 = 1/12.

x = 6
AC = 4x+17
= 4*6 + 17
= 24 +17
= 41°
Answer:
The measure of AC is 41°
Step-by-step explanation:
Given : ∠ABC = (4x-3.5)°
Arc AC = (4x+17)°
An inscribed angle: An angle with its vertex on the circle and whose sides are chords.
The intercepted arc : The arc that is inside the inscribed angle and whose endpoints are on the angle.
The Inscribed Angle Theorem : The measure of an inscribed angle is half the measure of its intercepted arc.
Uisng the theorem
[tex]\angle{ABC}=\frac{1}{2} \text{arc(AC)}[/tex]
[tex](4x-3.5)^{\circ}=\frac{1}{2} (4x+17)^{\circ}[/tex]
[tex]2*(4x-3.5)^{\circ}= (4x+17)^{\circ}[/tex]
[tex]8x-7= 4x+17[/tex]
[tex]4x=24[/tex]
[tex]x=\frac{24}{4}[/tex]
[tex]x=6[/tex]
So, Arc AC = (4x+17)° = (4*6+17)° = (24+17)° = 41°
Hence the measure of AC is 41°
