What is algebraic operation ?Any of the basic arithmetic operations—addition, subtraction, multiplication, division, raising to the power of a whole number, and taking roots (fractional power)—is considered an algebraic operation. These procedures could be applied to numerical data, in which case they are frequently referred to as arithmetic operations. Similar operations can be carried out on variables, algebraic expressions, and, more generally, on components of algebraic structures like groups and fields. Another way to describe an algebraic operation is as a function from the Cartesian power of a set to the same set.
Given that : Sheila made four withdrawals of each from an ATM. . She also made a $156 purchase with her check card. She then deposited her $375 salary.
It's difficult to determine the solution because we don't know how much money she had in her bank account before making 4 withdrawals, thus a like and rating would be really appreciated. We know she took out $40 four times, which is $160. She also used her card to make a $156 purchase, so when we sum the two amounts, we get $316. She then placed a check for $375 into the bank account, therefore we must deduct $316 from that sum to get at $59; but, since we deducted, Given that we end up with $59 rather than the money we wasted at the beginning, the fact that the price is higher than $316 indicates that there has been an increase.

Between −3 and −2, but closer to −2
Between 6 and 7, but closer to 6
Between 6 and 7, but closer to 7
Answer:
Between -3 and -2, but closer to -2

Write an equation of the line through the pair of points in slope-intercept form. (Lesson 3-4 )
(4,0) and (-3,-7)
y = x - 4 is an equation of the line in slope-intercept form passing through points (4 , 0) and (-3 , -7)
An equation of a line in slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept.
Given two points passed through by the line, you can use them to write the equation of the line in slope-intercept form.
1. Find the slope of the line using the two given points.
let Point 1(4 , 0) and Point 2(-3 , -7)
slope = m = (y2 - y1) / (x2 -x1)
m = (-7 - 0) / (-3 - 4)
m = -7/-7
m = 1
2. Use the value of the slope and one of the points to find the value of the y-intercept, b. Plug in these values in the formula for slope-intercept form.
y = mx+ b
y = 1x + b
Using Point 1,
0 = 1(4) + b
b = -4
3. Write the equation of the line in slope-intercept form.
y = mx+ b
where m = 1 and b = -4
y = x - 4

5years ago a woman was 4 times as old as her daughter.in four years time the woman will be two and a half times as old as her daughter.find their present age
At present, the age of the woman is 29 years, while the age of her daughter is 6 years.
In the question, we are given two characters, a woman and her daughter, and told to find their present age. We are also given some clues as to how we will arrive at the answer. Let's consider the first one.
In the first sentence, we are told that 5 years ago, the woman was 4 times as old as her daughter. We don't know the woman's age or her daughter's, so let's call the woman's present age x and her daughter's present age y for now. To know the age of the woman 5 years ago, we will subtract 5 from her current age, which will give us x - 5. Also, the woman was 4 times as old as her daughter 5 years ago, hence:
x - 5 = 4y
If we rearrange that; x = 4y + 5 (let's call this equation 1)
Now, on to the second clue.
In the second sentence, we are told that in four years time, the woman will be two and a half times as old as her daughter. The woman's age in 4 years time is x + 4, hence:
x + 4 = 2[tex]\frac{1}{2}[/tex]y
x + 4 = 5y/2
2x + 8 = 5y (let's call this equation 2)
Next, we will find the value of y (the daughter's present age) by substituting equation 1 into equation 2, that is, putting '4y + 5' in place of x in equation 2, thus:
2(4y + 5) + 8 = 5y
8y + 10 + 8 = 5y
8y - 5y = 18
3y = 18
y = 6
Therefore, at present, the daughter is 6 years old. To find the mother's age, we will substitute the daughter's age in place of y in equation 1:
x = 4y + 5
x = 4(6) + 5 = 29
Hence, the woman is 29 years old, and her daughter is 6 years old.

Find the coordinates of Z if Y is the midpoint of XZ, X(-10, 9), and Y(-4, 8).
The coordinates of Z are (2,7).
What is coordinates in math?
A pair of numbers that use the horizontal and vertical separations from the two reference axes to define a point's location on a coordinate plane. typically expressed by the x-value and y-value pair (x,y).
The formula to calculate the midpoint between two points is equal to
[tex]Y = ( \frac{(x_{1} + x_{2}) }{2} , (\frac{y_{1} + y{2} }{2} )[/tex]
we have
X(-10,9),Y(-4,8)
Let
(x2,y2) ----> the coordinates of Z
substitute the values
( -4.8) = ( -10 + x₂ /2 , 9 + y₂/2)
Solve for x2
-4 = ( -10 + x₂/2
-8 = -10 + x₂
x₂ = -8 + 10
x₂ = 2

For a fundraising project, your math club is publishing a calendar. The cost of the digital images and the permission to use them is $125. In addition to these “one time” charges, the unit cost of printing each calendar is $3.25.
Part a: Write an equation for the total cost of the calendars.
Part b: Write a model that gives the average cost A per calendar as a function of the number of calendars printed.
Part c: Use the graph of the model shown below to estimate the number of calendars that must be sold before the average cost drops to $5 per calendar.
The require answers are,
Part a: The equation for the total cost of the calendars is C = 125 + 3.25*100 = 350
Part b: The model that gives the average cost A per calendar as a function of the number of calendars printed is A = 125 + 3.25x
Part c: The estimate number of calendars that must be sold before the average cost drops to $5 per calendar is 70.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now it is given that,
Cost of the digital images and the permission = $125
“one time” charges = $3.25
Part a: The equation for the total cost of the calendars
THere are 100 calendars printed.
So, “one time” charge = 3.25*100
So, the total cost of the calendars C is given as,
C = 125 + 3.25*100
C = 125 + 325 = 450
Thus, the equation for the total cost of the calendars is given as,
C = 125 + 3.25*100 = 450
Part b: The model that gives the average cost A per calendar as a function of the number of calendars printed
Let there are x calendars printed
Total “one time” charges = 3.25x
So, Average cost is given as,
A = 125 + 3.25x
this is the model that gives the average cost A per calendar
Part c: The estimate number of calendars that must be sold before the average cost drops to $5 per calendar
Now from the graph it must be seen that the average cost drops to $ 5 per calender at 70.
Thus, number of calendars that must be sold before the average cost drops to $5 per calendar = 70
Thus, the require answers are,
Part a: The equation for the total cost of the calendars is C = 125 + 3.25*100 = 350
Part b: The model that gives the average cost A per calendar as a function of the number of calendars printed is A = 125 + 3.25x
Part c: The estimate number of calendars that must be sold before the average cost drops to $5 per calendar is 70.
