Slope=5, goes through the point (2,7)..
Answer:
the y-intercept is 7
Step-by-step explanation:
hope it helps. i just looked at the ordered pair and took the number that's on the y axis
Answer:
y=5x-3
Step-by-step explanation:
Slope intercept form is y=mx+b and you know the slope so you can get y=5x+b
Then you are given a point, (2, 7), so you can plug that into the equation to find the y-intercept
7=5(2)+b
Then you just solve for b
7=10+b
-10
-3=b
So the final equation is y=5x-3

The diagram shows a track composed of a rectangle with a semicircle on each end. The area of the rectangle is 6,600 square meters. What is the perimeter of the track? Use 3.14 for pi
Answer:
The perimeter of the track is the two circumferences of the semicircles (when combined, they form one circle, so we can just find the circumference of the circle) added to the lengths of the rectangle (160 meters).
To find the circumference of the circle, we need to know the diameter.
Circumference of a circle: dπ or 2rπ, where d represents diameter and r represents radius
The diameter of the circle happens to be the same as the width of the rectangle. We know that the area of a rectangle is found by multiplying its length by its width. We know that the area is 14400 and that its length is 160.
Width: area divided by length
14400160=90
The diameter of the circle and the width of the rectangle is 90 meters.
Circumference:
90⋅π=90π→ If you are using an approximation such as 3.14 for π, multiply that by 90
Add 160⋅2 to the circumference since the lengths of the rectangle are also part of the perimeter.
160⋅2=320
90π+320

What is the solution to the system of equations shown?
Please answer! Brainliest will be given, thanks :)
Answer:
2600, 3400, 5000, 7000
Step-by-step explanation:
This equation can be simplified to 200n + 1000. Now we can just plug in the amount of customers. 200 * 8 + 1000 = 2600. 200 * 12 + 1000 = 3400. 200 * 20 + 1000 = 5000, and 200 * 30 + 1000 = 7000.
given that there is one possible outlier. if the outlier was removed from the data set, how would it effect the measures of central tendency? {8, 73, 74, 75, 79, 85, 85, 92, 94}

O Mean increases median decreases
O Mean decreases median increases
O Both mean and median increase
O Both mean and median decrease
Answer:
Some measures I believe you are talking about are mean, median, mode, and range.
Mean is the average of all values. This is found by adding up all numbers and dividing by the amount of numbers. Outliers greatly affect and "throw off" the mean, making it inaccurate at calculating the average without an outlier.
Example:
1, 2, 4, 6, 10
(1 + 2 + 4 + 6 + 10)/5 = mean = 4.6
1, 2, 4, 6
(1 + 2 + 4 + 6)/4 = mean = 3.25
Because of this, mean does change when adding and removing outliers, and is therefor not the answer.
Median is the middle of the data. This is found by ordering the values in the data set from least to greatest (or greatest to least, either one works) and finding the number in the center of all the values. If there were an outlier, the median wouldn't be skewed as the mean is by outliers, but it would change.
Example:
1, 2, 4, 6, 10 Median = 4
1, 2, 4, 6 Median = 3
So median is not the answer, because it is affected by adding and removing outliers.
Mode is the value in a data set that appears the most. Outliers are numbers that are significantly lower or higher than most or all of the other numbers in a data set. Because of this, there can't be more outliers than other numbers, so it is impossible for the mode to be an outlier.
Example:
1, 1, 1, 2, 3, 4, 4, 86 Mode = 1
1, 1, 1, 2, 3, 4, 4 Mode = 1
This means the mode is not affected by adding and removing outliers.
Mode is a possible answer, but let's take a look at range before coming to a conclusion.
Range is the spread of values in a data set. In other words, the difference between the highest and lowest value. A high range can signal a possible outlier is present.
Example:
1, 2, 4, 6, 10
10 - 1 = highest value - lowest value = range = 9
1, 2, 4, 6
6 - 1 = highest value - lowest value = range = 5
The range is certainly affected by outliers, so it is not the answer.
Out of mean, median, mode, and range, the answer to this question is mode.
If an outlier is removed, mode will not change.
Hope this helps!

Answer:
1. you answered correctly :)
2. how many 1/4's go into 12? in other words multiply 12 and 4 to get 48/4
3. Draw a diagram of 1/5ths until it equals 15 (you'll need a total of 75 boxes)
4. the problem is 18z=72 so you need to divide 72 and 18. 72/18=4. therefore z equals 4.
5. make up a division problem that has the answer of 8. for example 24/y=3. y will equal 8. and then use a tape diagram for that.
6. make up a multiplication problem that has an answer of 8. for example 3y=24. y will equal 8. and then use a tape diagram for that.
7. Meghan is correct. when you have y divided by two you need to do the opposite and multiply both sides by two. Meredith was incorrect because she switched the division and multiplication signs completely which is not what you are supposed to do.

I will solve these equations algebraically.
Here you are:
1. 30= 5w
Divide each side by 5.
30÷5= 5w÷5
6 = w
∴ w= 6
To check,
30=5w
Substitute w for 6
30= 5 x (6)
30= 30
LS= RS
(You were correct, great job!)
2.
12 = x÷4
Multiply each side by 4.
12 x 4 = x/4 x 4 ↔ 4 and 4 cancel out.
48= x
∴ x=48
Checking:
12= 48÷4
12= 12
LS=RS
3.
y÷5=15
Multiply each side by 5.
y÷5 x 5= 15 x5
y =75
∴y=75
Checking:
Substitute y for 75.
y÷5=15
75÷5=15
15=15
LS=RS
4.
18x=72
Divide each side by 18.
18x ÷ 18= 72÷18
x = 4
∴x= 4
Checking
18x=72
18(4)=72
72=72
LS=RS
I hope that these solutions helped you. I am sure that using the solutions, you can figure out the other questions on your own.

4.) Dylan scored a 95, 78 and 89 on his first three science tests. Write and solve an inequality to determine what is the lowest possible score he can get on his fourth test to average at least a 90 in the class.
Answer:
98
Step-by-step explanation:
Dylan must get at least a 98% to reach an average of 90. (95+78+89+98)÷4=90.
