Which of the following equations are linear functions? Explain how you got your answer.
Select the three linear functions.
A. y = x to the power of 2 - 1
B. y = 2x + 1
C. y = 1/2x - 5
D. y = 1/3x to the power of 2
E. y = -x
Answer:
B, C, and E
The reason B, C, and E are the answer's is because the equation of a linear equation is y= mx+b. B, C, and E are written this way. We can eliminate A and D because They are quadratic equations, because the X is squared.

If a square has an area of 100ft², what is the length of one of the sides.
Answer:
The length of one side is 10 feet
Step-by-step explanation:
This is because the area of a square can be found through the formula side x side or [tex]side^{2}[/tex]. You can find the length of one side by finding the square root of the area. You would get both a positive and negative value for the square root but you want a positive value because a length cannot be negative.

Eddie purchased 15 boxes of paper clips and 7 packages of index cards for a total of $55.40. Finn bought 12 boxes of paper clips and 10 packages of index cards for $61.70. Find the cost of one box of paper clips and one package of index cards
The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95
Step-by-step explanation:
Eldora and Finn went to an office supply store together
Eldora bought 15 boxes of paper clips and 7 packages of index cards for a total cost of $55.40
Finn bought 12 boxes of paper clips and 10 packages of index cards for a total cost of $61.70
We need to find the cost of one box of paper clips and the cost of one package of index cards
Assume that the cost of one box of paper clips is $x and the cost of one package of index cards is $y
∵ x represents the cost of one box of paper clips
∵ y represents the cost of one package of index cards
∵ Eldora bought 15 boxes of paper clips and 7 packages of
index cards for a total cost of $55.40
∴ 15x + 7y = 55.4 ⇒ (1)
∵ Finn bought 12 boxes of paper clips and 10 packages of
index cards for a total cost of $61.70
∴ 12x + 10y = 61.7 ⇒ (2)
Now we have system of equations to solve it
Multiply equation (1) by -10 and equation (2) by 7 to eliminate y
∵ -10(15x) + -10(7y) = -10(55.4)
∴ -150x - 70y = -554 ⇒ (3)
∵ 7(12x) + 7(10y) = 7(61.7)
∴ 84x + 70y = 431.9 ⇒ (4)
Add equations (3) and (4)
∵ (-150x + 84x) + (-70y + 70y) = (-554 + 431.9)
∴ -66x = -122.1
- Divide both sides by -66
∴ x = 1.85
Substitute the value of x in equation (1) or (2) to find y
∵ 12(1.85) + 10y = 61.7
∴ 22.2 + 10y = 61.7
- Subtract 22.2 from both sides
∴ 10y = 39.5
- Divide both sides by 10
∴ y = 3.95
The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95

The first step that we must take before attempting to solve a problem is to understand what the problem statement is asking from us and what is given to us to help accomplish that goal. Looking at the problem statement, it asks us what the probability of choosing a vegetable is. We are given information about how many dishes of each type of food there is out of 10 dishes.
The next step that we need to do is to collect the total amount of vegetable dishes that have been listed in the problem statement along with the total amount of dishes. We know that there are 10 covered dishes and that there are 2 broccoli and 2 carrot which adds up to 4 vegetable dishes.
Now that we have that information we can move onto the final part which is to determine the probability of choosing a vegetable dish. We can do this by dividing the total amount of vegetable dishes from the total amount of dishes.
Determine the probability
[tex]\textsf{probability = (vegetable dishes) / (total dishes)}[/tex][tex]\textsf{probability = (4) / (10)}[/tex][tex]\textsf{probability = (4/2) / (10/2)}[/tex][tex]\textsf{probability = (2) / (5)}[/tex]Therefore, looking at the options that best matches the answer that we got we can confidentially say that it is option A, 2/5.
[tex]\huge\text{Hey there!}[/tex]
[tex]\text{Your equation: }\rm{\dfrac{number\ of\ the\ vegetables (the\ carrots\ \& \ the \ broccolis)}{total\ meals\ you\ have\ all\ together} = probability}\\\\\rm{\dfrac{2\ carrots + 2 \ broccolis}{10\ meals} = probability}\\\\\text{2 + 2 = \boxed{\mathbf 4} , right?}\\\\\rm{\dfrac{4}{10} = probability}\\\\\rm{\dfrac{4\div2}{10\div 2} = probability}\\\\\rm{\dfrac{2}{5} = probability}\\\\\\\huge\text{Therefore, your answer should be: \boxed{\mathsf{\dfrac{2}{5}}}}\huge\checkmark[/tex]

What is the slope of the table.
Answer:
slope is -5
Step-by-step explanation:
The formula for slope is:
m = (y2 - y1)/(x2 - x1)
m = slope
y2 = y-coordinate of second point
y1 = y-coordinate of first point
x2 = x-coordinate of second point
x1 = x-coordinate of first point
We can choose our first and second points as any points on the table, but we will choose the first andd second points which are (-5,10) and (-3,0).
y2 = 0
y1 = 10
x2 = -3
x1 = -5
m = (0-10)/(-3-(-5))
m = (-10)/(-3+5)
m = (-10)/(2)
m = -5

Given l\parallel m\parallel nl∥m∥n, find the value of x.
Answer:
x = 57
Step-by-step explanation:
x - 5 and 2x + 14 are angles on the same side of the transversal between two parallel linesThey are supplementary [add up to 180°]x - 5 + 2x + 14 = 1803x + 9 = 1803x = 171x = 57The value of x is 57.
What are properties of parallel lines?Properties of Parallel Lines
The pairs of corresponding angles are equal.The pairs of vertically opposite angles are equal.The pairs of alternate interior angles are equal.The pairs of alternate exterior angles are equal.Given:
lime m || n
So, using the property of parallel lines we have the angles on the same side of transversal are supplementary
x- 5 + 2x +14= 180
3x + 9 = 180
3x = 171
x= 171/3
x= 57
Hence, the value of x is 57.

Dale polled the 2 fastest swimmers on the swim team.
Is this sample of the swimmers on the swim team likely to be representative?
Answer as Yes or No
Reason:
Dale is biased toward the two fastest people in the group, but is leaving out the rest of the swimmers who may not be so fast. The people left out may be very distant from the top two swimmers. Therefore, Dale has not picked a representative sample.
As an example with numbers, let's say we had these average speeds in mph: {1, 2, 3, 4, 20, 30}. Of course these are just hypothetical examples and not based on actual realistic speeds; however, the example should still suffice.
That data set shows the average is closer to 2 and 3 than it is to 20 and 30. Dale polling the fastest people greatly skews the mean larger than it should be.
To get a better more representative sample, Dale should randomly pick 2 people regardless if they are the top two swimmers or not. He can pick the names out of a hat, or use a computer program to generate random numbers.
