What is the equation of this line in slope intercept form?
y = mx + b

m = slope
b = y-intercept

We can see that:

Part A: 3 appointments

Part B: 5 appointments

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.

Part A

Let x = number of dog grooming appointments Macy had in one day.

Given information:

Charge per appointment = $60

Total amount earned = $220

Total amount of tips earned = $40

Create an equation with the given information:

⇒ 60x + 40 = 220

Solving the equation:

Subtracting 40 from bothsides, we have:

⇒ 60x + 40 - 40 = 220 - 40

⇒ 60x = 180

⇒ 60x ÷ 60 = 180 ÷ 60

⇒ x = 3 appointments.

Part B

Let x = number of dog grooming appointments Logan had.

Given information:

Charge per appointment = $70

Total amount earned = $300

Total amount of tips earned = $50

Rental fee per appointment = $20

Create an equation with the given information:

⇒ 70x - 20x + 50 = 300

Solve the equation:

⇒ 50x + 50 = 300

⇒ 50x + 50 - 50 = 300 - 50

⇒ 50x = 250

⇒ 50x ÷ 50 = 250 ÷ 50

⇒ x = 5 appointments.

A bijective function is a function that is both one-to-one and onto, meaning that it assigns a unique output to each input, and every output in the codomain is assigned by some input in the domain.

If A has N elements and B has M elements, and we want to find the number of possible bijective functions from A to B, we can use the following formula:

Number of bijective functions = (Number of functions from A to B) / (Number of one-to-one functions from A to B)

The number of functions from A to B is given by the number of ways to assign each element of set A to set B, which is [tex]M^N[/tex].

The number of one-to-one functions from A to B is given by the number of ways to assign a unique element from set B to set A, which is[tex]M!/(M-N)![/tex]

The coordinate of point A(2,1) after dilation of 2 will be (4,2).

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size.

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Answer:

8, 3

Step-by-step explanation:

28, 23, 18, 13

Subtract each term from the next term.

23 - 28 = -5

18 - 23 = -5

13 - 18 = -5

All differences are equal. When all differences are equal, you have an arithmetic sequence. The equal differences are called the "common difference." To find a new term, add the common difference to the previous term.

13 + (-5) = 13 - 5 = 8

8 + (-5) = 8 - 5 = 3

Answer: 8, 3

Part A:

We want to see how often the number 4 comes up when we roll a fair dice 100 times. We will use a dice with numbers 1,2,3,4,5,6. We will keep track of how many times 4 comes up and we think it should be around 16 times because there are 6 numbers on the dice.

Part B:

We rolled the dice 100 times and got 4 32 times.

-We want to know if that is normal or if something is wrong with the dice.

-We use special numbers to check if this is normal, it's called the confidence interval

-The confidence interval tells us if 32 times is normal or not.

Part C:

The confidence interval tells us that 32 times is not normal, it's unlikely that it happened by chance. So, the dice might not be fair.

The order of rotational symmetry is the number of times a shape can be rotated and still look the same.

Generally, The amount of times that a form may be rotated through 360 degrees with maintaining its appearance is referred to as its rotational symmetry.

For instance, a circle has an order of rotational symmetry of infinity, which means that it can be rotated any number of times and still look the same.

On the other hand, a square has an order of rotational symmetry of 4, which means that it can be rotated by 90 degrees four times while maintaining its original appearance.

Answer: The slope is -1/5

The equation parallel to the given line is y=-1/4 x+5.

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

The given equation is y =-1/4 x+7 and the coordinate point is (8, 3).

Here, slope is -1/4

We know that, the slope of parallel lines are equal.

Now, substitute m=-1/4 and (x, y)=(8, 3) in y=mx+c, we get

3=-1/4 (8)+c

c=5

Substitute m=-1/4 and c=5 in y=mx+c, we get

The rectangle has a length of 222 feet and a width of 150 feet.

A quadrilateral with parallel sides equal to one another and four equal vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason.

Rectangles can also be referred to as parallelograms since their opposite sides are equal and parallel.

We know that the perimeter of a rectangle is the sum of all four sides. So in this case:

Perimeter = 2(length) + 2(width)

Given that the perimeter is 446 feet, we can set up the equation:

446 = 2(13x-1) + 2(9x+4)

On Simplifying, we get:

446 = 44x + 6

Now we can solve for x by subtracting 6 from both sides:

440 = 44x

Finally, dividing both sides by 44:

x = 10 feet

Now that we know the value of x, we can substitute it back into the expressions for the length and width:

Length = (13x-1) = (13(10)-1) = 129 feet

Width = (9x+4) = (9(10)+4) = 94 feet

Therefore, the rectangle has a length of 129 feet and a width of 94 feet.

Amber and Jeica go out for lunch. Amber’ lunch cot $11. 70, and he tip 18%. Jeica’ lunch cot $12. 30, and he tip 15%, then the percentage of tip is = 33.9%

Define Percentage :

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means.

Given that the Amber’ lunch cot is $11.70.

There is a 18% tax.

Therefore the tax on $11.70 is,

= $11.70×18%

= $2.106

The Amber’ lunch cot with tax is $(11.70 + 2.106)

= $13.806.

The Jeica’ lunch cot is $12.30.

There is a 15% tax.

Therefore the tax on $12.30 is,

= $12.30×15%

= $1.845

The Amber’ lunch cot with tax is $(12.30 + 1.845)

= $14.145.

The tip that is given is $(14.145 - 13.806)

= $0.339

The percentage of tip is

= $0.339 * 100

Therefore,

Amber and Jeica go out for lunch. Amber’ lunch cot $11. 70, and he tip 18%. Jeica’ lunch cot $12. 30, and he tip 15%, then the percentage of tip is = 33.9%
