What is algebraic ?
Algebraic refers to anything that pertains to algebra, which is a branch of mathematics that deals with mathematical symbols and the rules for manipulating these symbols. Algebraic concepts include using variables (such as x or y) to represent unknown values, using operations such as addition, subtraction, multiplication and division.
Let x be the number of adult-sized t-shirts that Antionette purchases.
We know that ,
The cost of each adult-sized t-shirt is $6.25
The cost of each youth-sized t-shirt is $4.50
Antionette has $550 to purchase both adult-sized and youth-sized t-shirts
Antionette purchases 45 youth-sized t-shirts
We can set up the equation to represent the total cost of all the t-shirts and the money Antionette has ,
(x6.25) + (454.50) = 550
To solve for x, we can simplify the equation by multiplying the number of adult-sized t-shirts by the cost per t-shirt and the number of youth-sized t-shirts by the cost per t-shirt, and then set it equal to the total money Antionette has ,
x*6.25 + 202.5 = 550
then we can subtract 202.5 from both sides , x*6.25 = 347.5
then divide both sides by 6.25 to get , x = 56
So, Antionette can purchase a maximum of 56 adult-sized t-shirts.

Margo can purchase tile at a store for $0.59 per tile and rent a tile saw for $18. At another store she can borrow the tile saw for free if she buys tiles there for $1.19 per tile. How many tiles must she buy for the cost to be the same at both stores?
Answer:
30 tiles
Step-by-step explanation:
We know
First store
$0.59 per tile
Rent a tile saw for $18
Second store
1 tile = $1.19
We have the equation
0.59x + 18 = 1.19x
18 = 0.6x
x = 30 tiles
So, she must buy 30 tiles for the same cost at both stores.
Answer:
Margo must purchase 30 tiles for the cost to be the same at both stores.
Step-by-step explanation:
By analyzing the "real-world" problem, we can convert the words into two algebraic equations.
Step 1:Store 1:
"$0.59 per tile and rent a tile saw for $18."
y = 0.59x + 18
y = the price of the tiles bought
0.59 = price of one tile
x = number of tiles
18 = the fixed cost of a saw
Store 2:
"At another store, she can borrow the tile saw for free if she buys tiles there for $1.19 per tile."
In this case, the saw is free. Thus, we don't need to add a price to the equation.
y = 1.19x
y = the price of the tiles bought
1.19 = price of one tile
x = number of tiles
Step 2:Now that we have both equations, we can write down the equations that equate other. This formula will indicate that the equations would intersect at a certain point on the x and y values. Hence, this step will answer how many tiles are required for both stores to equal the same price.
[tex]0.59x+18=1.19x[/tex]
Now solve for x:
[tex]0.59x-0.59x+18=1.19x-0.59x\\\\18=0.6x\\\\\frac{18}{0.6} =\frac{0.6x}{0.6}\\\\30=x[/tex]
Margo can buy 30 tiles from both stores for the cost to be equal.
You might ask, "But what about the price?" This is where we solve for y; this variable will answer how much the tiles would cost at 30 tiles. So, we can take the answer for "x" and plug it into any of the two equations.
[tex]y=1.19x\\y=1.19(30)[/tex]
For this equation, all you have to do is multiply both numbers to get your answer.
[tex]y=35.7[/tex]
Bottom Line:Therefore, Margo can buy 30 tiles for the cost to be same at both stores at $35.70.
What is the range is called?.
The set of all the outputs of a function is known as the range of the function or after substituting the domain, the entire set of all values possible as outcomes of the dependent variable.
For e.g. the range of the function F is {1983, 1987, 1992, 1996}.
On the other hand, the whole set B is known as the codomain of the function.
It is the set that contains all the outputs of the function.
So, the set of real numbers is a codomain for every real-valued function. The codomain of the function F is set B.
How to Find the Range of a Function
Consider a function y = f(x).
The spread of all the y values from minimum to maximum is the range of the function.
In the given expression of y, substitute all the values of x to check whether it is positive, negative or equal to other values.

There are several ways to find the measure of an angle in a triangle, depending on the information given about the triangle and the angles. Some common methods include:
Using the angles in a triangle sum to 180 degrees: If you know the measures of two angles in a triangle, you can use the fact that the angles in a triangle sum to 180 degrees to find the measure of the third angle.
Using the Pythagorean theorem: If you have a right triangle, you can use the Pythagorean theorem to find the measure of the right angle (90 degrees)
Using the Law of Cosines: If you know the measures of two angles and the lengths of all three sides of a triangle, you can use the law of cosines to find the measure of the third angle.
Using trigonometry: If you know the lengths of two sides of a triangle and the measure of one angle, you can use trigonometry to find the measure of the other angles.
It is important to note that in order to find the measure of an angle you need to know at least one angle and the values of the sides of the triangle or two angles.
What is linear inequality in two variables and linear equation in two variables?.
A linear inequality in two variables is an inequality that can be written in the form "ax + by < c" or "ax + by > c" or "ax + by = c", where a, b, and c are constants and x and y are variables. This inequality represents a boundary line and all the solutions of the inequality make up a region of the xy-plane.
For example, the inequality "2x + 3y < 6" represents the region of the xy-plane that is on one side of line 2x + 3y = 6. To graph this inequality, one can find the boundary line by setting the inequality equal to zero and then shading in the region that satisfies the inequality.
A linear equation in two variables is an equation that can be written in the form "ax + by = c", where a, b, and c are constants and x and y are variables. This equation represents a straight line in the xy-plane and all the solutions of the equation are the coordinates of the points on that line.

3x + 2y = 1
5x + 4y = 5
Answer:
x = -3
y = 5
Step-by-step explanation:
3x + 2y = 1
5x + 4y = 5
First, we multiply the first equation by -2
-6x -4y = -2
5x + 4y = 5
-x = 3
x = -3
Now put -3 back in for x and solve for y
3(-3) + 2y = 1
-9 + 2y = 1
2y = 10
y = 5
Let's check
3(-3) + 2(5) = 1
-9 + 10 = 1
1 = 1
So, x = -3 & y = 5 is the correct answer.
What is the solution of the equations 8x +3y 5 and 3x 2y 5?.
The solution of the given linear equations is (x,y) = (1,-1).
The given linear equations are
8x + 3y = 5 - - - ( 1 )
3x - 2y = 5 - - - ( 2 )
As the RHS of both equations is equal, equating the LHS of both equations, we get,
8x + 3y = 3x - 2y
⇒ 8x - 3x = - 2y - 3y
⇒ 5x = - 5y
⇒ x = - 5y ÷ 5
⇒ x = - y
By substituting x = - y in equation ( 1 ), we get,
8x + 3y = 5 - - - ( 1 )
⇒ 8 ( - y ) + 3y = 5
⇒ - 8y + 3y = 5
⇒ - 5y = 5
⇒ y = - 5 ÷ 5
⇒ y = - 1
Now,
x = - y
⇒ x = - ( - 1 )
⇒ x = 1

For a ride on a rental scooter, Boris paid a $8 fee to start the scooter plus $6 cents per minute of the ride. The total bill for Boris's ride was $19.58 . For how many minutes did Boris ride the scooter?
Answer:
193 minutes
Step-by-step explanation:
We know
Boris paid an $8 fee to start the scooter plus 6 cents per minute of the ride.
Let y represent the total cost and x represent the number of minutes we have the equation
y = 0.06x + 8
Now, put $19.58 in for y and solve
19.58 = 0.06x + 8
11.58 = 0.06x
x = 193 minutes
So, Boris rides the scooter for 193 minutes.
How do you plot a point?.
An x-y (or bivariate) plot is any graph or plot with two axes. The "x-axis" is typically the horizontal axis, whereas the "y-axis" is typically the vertical axis.
Your plot's axes should be identified, and the scale should be chosen (if the graph is not already labeled). Plot the first two pairs of numbers first (the top row of numbers).
Finding the number a on the horizontal, or x-, axis and tracing up or down from there while maintaining a parallel path to the vertical, or y-, axis, will allow you to draw the point at (a, b) on the Cartesian plane.
The position of the point is this area (a, b). The intersection of the two axes defines the plane's center. It is referred to as the beginning or point (0,0).
Each axis is further subdivided into equal units starting at the origin: rising, positive numbers on the x-axis and up the y-axis; falling, negative numbers on the x-axis and down the y-axis.
