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

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.

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.

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:

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

Answer:

Step-by-step explanation:

Answer:

f(x)=a(x - h)2 + k

Much like a linear function, k works like b in the slope-intercept formula. Like where add or subtract b would determine where the line crosses, in the linear, k determines the vertex of the parabola. If you're going to go up 2, then you need to add 2.

The h determines the movement horizontally. what you put in h determines if it moves left or right. To adjust this, you need to find the number to make the parentheses equal 0 when x equals -2 (because moving the vertex point to the left means subtraction/negatives):

x - h = 0

-2 - h = 0

-h = 2

h = -2

So the function ends up looking like:

f(x)=a(x - (-2))2 + 2

Subtracting a negative cancels the signs out to make a positive:

f(x)=a(x + 2)2 + 2

Step-by-step explanation:

The translated value of the function is h ( x ) = ( x + 4 )² - 7

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = x²

we can obtain the function h(x) by first translating it 4 units to the left, which gives us f(x + 4), and then translating it 7 units down, which gives us f(x + 4) - 7. Therefore, the function h(x) can be written as:

h(x) = f(x + 4) - 7

To write this in vertex form, we need to complete the square. First, we have:

h(x) = f(x + 4) - 7

h(x) = (x + 4)² - 7

This is the vertex form of the equation for h(x). The vertex of the parabola is at the point (-4, -7), which is obtained by setting x + 4 = 0 in the equation above.

The value of the vertex is -7, which is obtained by subtracting 7 from the squared term.

Therefore, the vertex form of the equation for h(x) is:

h ( x ) = ( x + 4 )² - 7

Hence , the transformed function is h ( x ) = ( x + 4 )² - 7
