The expression that represents the total cost of buying and shipping the baseball cards,
= 6(1.75) + 5(9.5) + 2(20.5) + 4
What is addition?Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.
Given:
Jake is buying baseball cards for his brother in college.
The price of a card is based on its condition.
The table shows the total cost of x number of cards for each condition.
He buys 6 that are in fair condition, 5 that are in good condition, and 2 that are in excellent condition.
The shipping cost for the baseball cards is $4.00.
The expression that represents the total cost of buying and shipping the baseball cards,
= 6(1.75) + 5(9.5) + 2(20.5) + 4
= 10.5 + 47.5 + 41 + 4
= 103
Therefore, the total cost is $103.

Sol divided the following polynomial and made a mistake (x³ + 8x - 16) + (x-2)
There are an equal number of roots as long as there are x powers. As a result of the four xs, the polynomial in this situation has four roots.
How can the roots of a polynomial be found given its factored form?Finding the roots of the polynomial will allow you to solve it. P(x) = 0 is obtained by setting each factor to 0 and then calculating x. The polynomial equation can be solved by factoring. For every factor, a value of 0 should be used. 2x4 = 0; (x - 6) = 0; (x + 1) = 0 the answer to x, please.
It's important to note this even if there are only two genuine roots. The final two roots of this equation, which contain the integer I, are not real because I appears in both of them.

What is the solution of the equation 2x y 5 and 3x 2y 4?.
Solving the 2 equations will give us the value of x to be -14 and that of y to be 33.
Here we have two equations
2x + y = 5 and 3x - 2y = 4
Now we will use the substitution method to solve the equations
The first equation is
2x + y = 5
or, y = 5 - 2x [1]
Let 3x - 2y = 4 be equation 2
Substituting the value obtained in equation [1] in [2] we get
3x - 2(5 - 2x) = 4
or, 3x - 10 + 4x = 4
or, x = -14 [3]
Substituting the value of x obtained in equation [3] to equation [1] we get
y = 5 - 2(-14)
or, y = 5 + 28
or, y = 33
Hence, x = -14 and y = 33

Muic player A: y= 191x-32
Muic player B: y=-x^2200x20
A. On what day did the company ell the ame number of each player?
B. How many player were old on that day?
a. On the 13th day the company sold the same number of each player.
b. 2,451 players were sold on that day.
a. The day on which the company sold the same number of players can be calculated by equating the values of y that we have ;
y = 191x-32 and y = -x² + 200x + 20
Equating both, we have;
191x-32 = -x² + 200x + 20
⇒x² -200x + 191x-20-32 = 0
⇒x²-9x-52 = 0
⇒x²-13x + 4x -52 = 0
⇒x(x-13)+4(x-13) = 0
⇒(x-13)(x+4) = 0
⇒x = 13 or -4
as days cannot be negative, so we choose only x = 13
This means that the company sold equal numbers of players on the 13th day.
b. To get the number of players sold on that day, we select any of the y equations and substitute x = 13
Thus, y = 191x -32; 191(13) - 32 = 2,451 players

Is Y =- 5x 3 linear or nonlinear?.
The equation y = -5x + 3 is a linear equation.
We know that a linear equation in two variables is nothing but an equation that can be written in the form Ax + By = C, where A and B are real numbers and A ≠ 0, B ≠ 0.
The above form of equation is called the standard form of a linear equation in two variables.
Here we have been given an equation y = -5x + 3
y = -5x + 3
y + 5x = -5x + 3 + 5x ........(Add 5x to each side)
y + 5x = (-5x + 5x) + 3 .......(Associative property of addition)
y + 5x = 0 + 3
5x + y = 3 ........(Commutative property of addition)
Since we can write it in the standard form, Ax + By = C, then we have a linear equation.

How do you calculate equivalent form?.
To calculate equivalent form of an algebraic expression we can use the following :
1) distributing property
2) factoring.
Two mathematical expressions are said to be equivalent if they yield the same result upon solving them. To represent equivalent form an equality (=) sign is used. 3(x + 2) and 3x + 6 are equivalent expressions because the value of both the expressions remains the same for any value of x. To calculate equivalent form by using Distributive Property :
Start with an algebraic expression. Let's take an example 2x(3y + 2).Distribute the multiple 2x throughout the rest of the equation. That is multiplying 2x by 3y and by 2, we get 6xy + 4x.This is our equivalent expression. It can be represent as equality : 2x(3y + 2) = 6xy + 4x.To calculate equivalent form Using Factoring :
Identify the common factors in the expression. If possible divide the equation to find an equivalent expression.Let the expression 5xy + 4x, in this case, both numbers 4 and 5 are co-prime. As we see that there is common factor, x. Take the other common factors: x(5y + 4).This gives you an equivalent form . Again, the equality form, 5xy + 4x = x(5y + 4). Thus, the required equivalent form is determined.

A city planner wants to build a road perpendicular to D Street. What should be the slope of the new road?
The slope of the new road is zero.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Take points from the Graph (5, 0) and (5, 4).
Slope of a line = m = tanθ
where θ is the angle made by the line with the x−axis.
For a line parallel to y−axis ,θ= π/2.
∴m = tan π/2 = undefined
The new road will therefore have 0° of inclination if it is perpendicular to D street because if they are perpendicular and D street is vertical, the new road is level and has 0° of inclination.
An horizontal line now has zero slope.

In the given question, we have to find the solution of the system of equations y = 4x + 4 and y = -3x - 3.
The given equations are:
y = 4x + 4.....................(1)
y = -3x - 3.....................(2)
Now putting the value of y from equation 1 to the equation 2
4x + 4 = -3x - 3
Subtract 4 on both side, we get
4x = -3x - 7
Add 3x on both side, we get
7x = -7
Divide by 7 on both side, we get
x = -1
Now putting the value of x in equation 1
y = 4(-1) + 4
y = -4 + 4

How do you find the sides of a 30 60 90 triangle?.
A 30-60-90 triangle is a special type of right triangle that has angles of 30 degrees, 60 degrees, and 90 degrees. It has the following properties:
The side opposite the 30-degree angle is half the length of the hypotenuse (the side opposite the 90-degree angle).
The side opposite the 60-degree angle is √3 times the length of the side opposite the 30-degree angle.
To find the sides of a 30-60-90 triangle, you can use these properties.
If you know the length of the hypotenuse (the side opposite the 90-degree angle), you can find the length of the other two sides using the following formulas:
The side opposite the 30-degree angle: hypotenuse / 2
The side opposite the 60-degree angle: (√3) * (hypotenuse / 2)
If you know the length of one of the other two sides, you can use the above formulas to find the length of the hypotenuse and the other side.
For example, if you know the length of the side opposite the 30-degree angle, you can find the length of the hypotenuse by multiplying it by 2 and the length of the side opposite the 60-degree angle by multiplying it by √3
In summary:
The hypotenuse is always twice the length of the shorter leg.
The longer leg is √3 times the length of the shorter leg.
The hypotenuse is always the longest side in a 30-60-90 triangle.

Now, divide the expression into parts, we have;
3/-4 (x^⁻⁴y⁵/2x⁶y⁻¹⁴)
Since we are finding the quotient, subtract the exponents of the denominator from the numerators, we get;
3× -4(x⁻⁴⁺⁶y⁵⁻¹⁴)
