Melissa charges $1.25 per hour to pet-sit.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The table and the given points on the coordinate plane provide information about the relationship between the number of hours of
pet-sitting (x) and the amount of money earned (y) by Melissa, who charges a fixed rate of $1.25 per hour for pet-sitting.
The equation of the line passing through the points (1, 1.25) and (4, 5) can be found by using the slope-intercept form:
y - y_1 = m (x - x_1),
where m is the slope and (x_1, y_1) is a point on the line.
Using the two given points, we have:
m = (y_2 - y_1)/(x_2 - x_1)
= (5 - 1.25)/(4 - 1)
= 1.25
y - 1.25 = 1.25 (x - 1)
y = 1.25x - 0.75
This means that for each additional hour of pet-sitting, Melissa earns an additional $1.25.
Therefore,
The two variables in this problem are dollars and hours
Melissa charges $1.25 per hour to pet-sit.

solve the following equation for the variable indicated
15 = Зn + 6р, for n
Answer:
Solving the equation [tex]15 = 3n + 6p[/tex] for variable n we get [tex]\mathbf{n=5-2p}[/tex]
Step-by-step explanation:
We need to solve the equation [tex]15 = 3n + 6p[/tex] for variable n
Solving:
[tex]15 = 3n + 6p[/tex]
Subtract both sides by 6p
[tex]15-6p = 3n +6p -6p\\15-6p=3n[/tex]
Switch sides of equality
[tex]3n=15-6p[/tex]
Divide both sides by 3
[tex]\frac{3n}{3} =\frac{15-6p}{3}\\n=\frac{3(5-2p)}{3}\\n=5-2p[/tex]
So, solving the equation [tex]15 = 3n + 6p[/tex] for variable n we get [tex]\mathbf{n=5-2p}[/tex]

A sale person is given a choice of two salary plans 1weekly salary of $500 plus 4%commission of sale plan 2 is a straight commission of 8% of sales how much sales did she make in a week for both plans to result in the same salary?
Answer:
$12500
Step-by-step explanation:
Given that:
Salary plan 1:
Weekly salary of $500.
And a commission of 4%.
Salary plan 2:
Straight commission of 8%.
To find:
Weekly sales for which both the plans will make the same sales?
Solution:
Let the weekly sales = $[tex]x[/tex]
As per question statement:
Salary as per Plan 1 = $500 + 4% of [tex]x[/tex]
Salary as per Plan 2 = 8% of [tex]x[/tex]
Putting both the salaries to equal to find the total weekly sales.
$500 + 4% of [tex]x[/tex] = 8% of [tex]x[/tex]
[tex]\Rightarrow 500 = 4\%\ of\ x\\\Rightarrow 500 = \dfrac{4}{100}x\\\Rightarrow x = \$12500[/tex]
Therefore, the answer is:
For the sales of $12500, the salary will be same from both the plans.

Jack bought a new car. The price of the car was $18,936. He paid $3,000 upfront and got a loan for the remaining balance. If he paid the same amount each month for 4 years (at which point the car is paid off), how much was his monthly payment?
Answer:
Step-by-step explanation:
Given that:
Price of car = $18,936
Upfront paid = $3000
Time taken to pay remaining balance = 4 years
Amount paid per month if the same amount is paid per month
Remaining balance :
($18,936 - $3000) = $15,936
Number of months in 4 years = (12 * 4). = 48 months
Amount paid per month :
$15,936 / 48
= $332

Hope this helps plz hit the crown :D
Good Morning :^)
Question:
Yesterday, Bethany sent 60 text messages. She said that 15% of those
messages were to her best friend. How many text messages did Bethany
send to her best friend yesterday?
Well, let's figure this out!
Y is 15% of 60
Equation: Y = P% × X
First Step: Solve our equation for Y
Y = P% × X
Y = 15% × 60
Second Step: Convert percent to decimal:
p = 15%/100 = 0.15
Y = 0.15 * 60
Y = 9
Answer: Yesterday, Bethany sent 9 text messages to her best friend.
Which pair of angles are vertical angles?
/_ZRQW and /_ZWQV
/_ZRQT and /_ZTQV
/_ ZRQW and /_ZTQU
/_ZRQS and /_ZSQU
Answer:
(c) is correct.
Step-by-step explanation:
When two lines cross each other, the angles opposite to each other are called vertically opposite angles. They are always equal.
In this given figure,
Line TW and RU cross each other at Q, it means
[tex]\angle RQW=\angle TQU[/tex] (vertically opposite angles)
Hence, the correct option is (c).
The coordinates of the vertices of the preimage of a parallelogram are (1,5), (3,3), (3,7), and (5,5). The coordinates of the vertices of the image are (−5,3), (−3,1), (−3,5), and (−1,3).
How far and in what direction was the parallelogram translated? Write your answer using mapping notation and practice reading your answer aloud.
The actual image of the parallelogram has been translated by 6 units left and 2 units down of the preimage parallelogram.
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
Given the preimage of a parallelogram with vertices (1,5), (3,3), (3,7), and (5,5).
If we plot in the coordinate plane as shown below.
Now plot the image of a parallelogram with vertices (−5,3), (−3,1), (−3,5), and (−1,3).
If we take only one vertex of the preimage to let's say (1,5) now if we look at the corresponding vertex in the image then it is (-5,3).
1 + x = -5 ⇒ x = -6 (6 units left)
5 + y = 3 ⇒ y = -2 (2 units down)
Hence "The actual image of the parallelogram has been translated by 6 units left and 2 units down of the preimage parallelogram".

What is the mean absolute deviation of the following set of data?
10
20
12
4
18
8
14
18
Answer:
The mean absolute deviation of the following set of data is 4.5
Step-by-step explanation:
We need to find the mean absolute deviation of the following set of data.
10,20,12,4,18,8,14,18
For finding mean absolute deviation, first we need to find the mean of the given data set.
The formula used to calculate mean is: [tex]Mean=\frac{Sum\:of\:all\:data\:points}{Number\:of\:data\:points}[/tex]
Sum of all data points: 10+20+12+4+18+8+14+18 = 104
Number of data points = 8
So, mean is:
[tex]Mean=\frac{Sum\:of\:all\:data\:points}{Number\:of\:data\:points}\\Mean=\frac{104}{8}\\Mean=13[/tex]
Now, we will subtract 13 from the given data points:
10 - 13 = -3
20 - 13 = 7
12 - 13 = -1
4 - 13 = -9
18 -13 = 5
8 - 13 = -5
14 - 13 = 1
18 - 13 = 5
We will take absolute values i.e |-a|=a
So, now the numbers will be:
3,7,1,9,5,5,1,5
We will now find absolute mean deviation by finding mean of newly calculate values
Sum of all data points = 3+7+1+9+5+5+1+5
Number of data points = 8
[tex]Mean=\frac{Sum\:of\:all\:data\:points}{Number\:of\:data\:points}\\Mean=\frac{36}{8}\\Mean=4.5[/tex]
So, the mean absolute deviation of the following set of data is 4.5
xx squared - XY + x squared - xy
Answer and Step-by-step explanation:
[tex]x^{2} - xy + x^{2} -xy\\\\2x^{2} -2xy[/tex]
This is the answer.
In case your expression is:
[tex]x^2\:-\:xy\:+\:x^2\:-\:xy[/tex]
Solution:
Given the expression
[tex]x^2\:-\:xy\:+\:x^2\:-\:xy[/tex]
Group like terms
[tex]x^2\:-\:xy\:+\:x^2\:-\:xy=x^2+x^2-xy-xy[/tex]
Add similar elements: x²+x² = 2x²
[tex]=2x^2-xy-xy[/tex]
Add similar elements: -xy-xy = -2xy
[tex]=2x^2-2xy[/tex]
Thus,
[tex]x^2-xy+x^2-xy=2x^2-2xy[/tex]
In case your expression is:
[tex]\left(xx\right)^2\:-\:xy\:+\:x^2\:-\:xy[/tex]
Solution:
Given the expression
[tex]\left(xx\right)^2\:-\:xy\:+\:x^2\:-\:xy[/tex]
Group like terms
[tex]\left(xx\right)^2\:-\:xy\:+\:x^2\:-\:xy=x^2-xy-xy+\left(xx\right)^2[/tex]
Add similar elements: -xy-xy = -2xy
[tex]=x^2-2xy+\left(xx\right)^2[/tex]
as (xx)² = x⁴
so [tex]=x^2-2xy+x^4[/tex]
Therefore, we conclude that:
[tex]\left(xx\right)^2\:-\:xy\:+\:x^2\:-\:xy=x^2-2xy+x^4[/tex]the public library has 1,845 new books and 4,527 old books. Micah puts the same number of books on 9 shelves. How many books did he put on each shelf

Solve for the final amount you need to pay. Chinese foos $120 for delivery. You want to pay 15% tip. How much money total money will you give the delivery boy? Show work.
Answer:
$150
Step-by-step explanation:
Given
Delivery amount = $120
Percent tip on the delivery amount = 15%
Tip amount = 15% * 120
Tip amount = 0.15 * 120 = $30
Total money paid = Delivery amount + Tip
Total money paid = $120 + $30
Total money paid = $150
hence the total money you will give the delivery boy is $150
