Answer:
The value of the expression when x = -1 and y = 2 is -16.
Step-by-step explanation:
Firstly, let's look at [tex]x^{3}[/tex].
As the question provides, the value of x is -1. Therefore, we have to find the value of [tex](-1)^{3}[/tex], which is -1.
Now, moving onto [tex]y^{2}[/tex].
The question provides us with y = 2. Simply substitute this value into [tex]y^{2}[/tex], and we get [tex]2^{2} = 4[/tex].
Finally, concluding the equation, we get 4(-1)(4). That is equal to -16, which is our answer.
Hope this helped!

Find the solution of this system of equations
x - y = 4
- 10x + y = -58
Answer:
Step-by-step explanation:
given: x-y = 4
x=4+y
given: -10x + y = -58
plug in for x
-10(4 + y) + y = -58
-40 - 10y + y = -58
-9y = -18
y = -18 / -9
y = 2
now plug in 2 for y in the first equation
x-2=4
x=6
There is the solution x=6, y=2 :)
How are the areas of triangles and parallelograms in the coordinate
plane calculated?
Answer:
___________________________________________________________
By finding the product of a point's x coordinate times the next point's y coordinate, then subtracting the y coordinate of the first point times the x coordinate of the second coordinate and dividing by two, you will find the area of the polygon.

Yesterday, Jack drove 35 1/2 miles used 1 1/4 gallons of gasoline. What is the unit rate for miles per gallon?
Answer:
28.4 miles/gallon
Step-by-step explanation:
to find the answer, you need to find the constant by dividing the miles drove by the amount of gasoline (or the other way around in terms of wording if it is not correct grammar) So you need to do 35.5/1.25 . FYI I converted the fraction to decimal. The answer is 28.4 miles/gallon.
Hope this helped!! :)

Answer:
137°
Step-by-step explanation:
Basically, its the reverse of question 1.
With angle x, you can find out that the opposite angle is 360 - 106 = 254°
the angle is twice the size of angle y as said in the corcle theorems.
254 divided by 2 = 137°
(please correct me if im wrong, i feel like im missing something)

There are 7 boxes stacked on the floor in the math department supply closet. Each box has a height of 10 inches or 8 inches. The height of the stack of 7 boxes is 5 feet. How many boxes in the stack are 8 inches in height?
Answer:
5 of the 7 boxes are 8 inches in height
Step-by-step explanation:
Mathematically;
1 ft = 12 inches
So, 5 ft will measure 5 * 12 = 60 inches
So from what we have ,
We want to combine 8 and 10 inches to give 60 inches total
Let the number of 10 inches be x and the number of 8 inches be y
Mathematically;
x + y = 7 •••••(i)
10x + 8y = 60 ••••(ii)
From equation i, x = 7-y
Put this in equation ii
10(7-y) + 8y = 60
70-10y + 8y = 60
70-60 = 10y-8y
2y = 10
y = 10/2
y = 5
The greatest number of bat bags the coach can buy with $605 is
Choose...(10,11,12,13) .
She needs to buy
Choose...(10,11,12,13)
bat bags. The coach
Choose...(does not, does.)
have enough money to buy a bat bag for each player.
Answer:
11
12
does not
Step-by-step explanation:
If we know how much money the coach has and how much each bag costs we can find out how much bags the coach can by by divide the money the coach has by the price of one bat bag. So we do....
605 / 55 = 11
So now we know that she can by 11 bags maximum, while she needs 12 bags for the team. From this we know that she does not have enough money to buy 12 bags.

Solve please: 7(3x+1)=35
Answer:
x=
Step-by-step explanation:
PEMDAS:
35/ 7
3x+1 = 5
3x= 4
x= 4/3
Answer: x=4/3
Step-by-step explanation:
1. Distribute
7(3x+1)=35
21x+7=35
2. Subtract 7 from both sides of the equation
21x+7=35
21x+7-7=35-7
3. Simplify
Subtract the numbers
Subtract the numbers
21x=28
4. Divide both sides of the equation by the same term
21x=28
21x/21 28/21
5. Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
x=4/3

thank you!
Answer:
x = 6
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
4x - 8 = 16
Step 2: Solve for x
Add 8 to both sides: 4x = 24Divide 4 on both sides: x = 6Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 4(6) - 8 = 16Multiply: 24 - 8 = 16Subtract: 16 = 16Here we see that 16 does indeed equal 16.
∴ x = 6 is the solution to the equation.
Answer:
x=6
Step-by-step explanation:

Solve and describe the graph of the inequality: 5x < 45
Answer:
5x<45 Divide both by five which results in the equation looking like this:x<9. On a number line, there would be an open circle on the nine and the arrow would go to the left.
Step-by-step explanation:
The solution set is x<9 of inequality 5x<45.
What is an inequality?A relationship between two expressions or values that is not equal to one another is referred to as "inequality" in mathematics.
To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
5x<45
divide by 5
x<9
The graph is the shaded region below x =9.
Therefore, the solution set is x<9. And the graph is given.
