What is a linear equation?A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.
y = -2x - 4 ------------1
y = x + 2--------------2
Equating equation 1 and 2 we have
-2x - 4 = x + 2
collect like terms
-2x - x = 2 + 4
-3x = 6
x = 6/-3
x = -2
but y = x + 2
substitute x = -2
y = -2 + 2, y = 0
In conclusion the solution of the system of linear equations is (-2, 0 )

The required factors of the given polynomial is (r^4 + rs^5)(t^8 - (rs^5t^4) + r^2s^10).
What is factor?
A factor is a number that partitions another number, leaving no remainder portion. if multiplying two whole number gives us an item, the numbers we are increasing are variables of the item since they are separable by the item.
According to question:We have given,
t^12 - r^3(s)^15
By using formula
(a³ - b³) = ( a+ b)( a² -ab + b²)
Then,
(r^4)^3 - (rs^5)^3
(r^4 + rs^5)((t^4)^2 - rs^5t^4 + (r^5)^2)
(r^4 + rs^5)(t^8 - (rs^5t^4) + r^2s^10)
Thus, required answer is (r^4 + rs^5)(t^8 - (rs^5t^4) + r^2s^10), So option (D) is correct.

Part A: Write an equation that gives the volume at t hours after freezing begins. (2 points)
Part B: Find the surface area as a function of time, using composition, and determine its range. (4 points)
Part C: After how many hours will the surface area equal 216 square inches? Show all necessary calculations, and check for extraneous solutions. (4 points)
a) The equation for the volume of the cube after t hours is of: V(t) = (0.5t + 2)³.
b) The equation for the surface area of the cube after t hours is of: S(t) = 6(0.5t + 2)².
c) The surface area will be of 216 in² after 8 hours.
How to obtain the volume and the surface area of a cube?Considering a cube of side length s, the surface area and the volume are given as follows:
Surface Area: S(s) = 6s².Volume: V(s) = s³.In this problem, the side length is a function of the time, as follows:
s(t) = 0.5t + 2.
Hence the equations are given as follows:
Surface Area: S(t) = 6(0.5t + 2)².Volume: V(t) = (0.5t + 2)³.The surface area will be of 216 in³ when:
6(0.5t + 2)² = 216
(0.5t + 2)² = 216/6
(0.5t + 2)² = 36.
Taking the square root from both sides, the time is given as follows:
0.5t + 2 = 6
0.5t = 4
t = 4/0.5
t = 8 hours.

Rony spent 20% of his salary on a wallet. He bought a bag which cost $20 more than the wallet. He also bought a pair of shoes. The ratio of the cost of the wallet to the cost of the pair of shoes was 5:6. He then had $844 left.
(a) What was his monthly salary?
(b) Express the amount of money he spent on the pair of shoes as a fraction of his monthly salary in its simplest form.
The 20% Tony spends from his monthly salary on the wallet, the bag which cost $20 more than the wallet and the ratio of the wallet to shoe cost of 5:6, which expressed as a fraction is 5/6, indicates;
(a) Tony's monthly salary is $2,400
(b) The amount spent on the pair of shoes is (6/25) of his monthly salary
What is a fraction?A fraction is a part of a whole item, expressed as a quotient.
Let x represent Tony's salary, from the details of the question, we get;
The amount Tony spent on the wallet = 20% of his salary
The cost of the bag Tony bought = $20 + The cost of the wallet
Ratio of the cost of the wallet to the cost of the pair of shoes = 5:6
The amount Tony had left = $844
Therefore;
The amount Tony spent on the wallet = 20% of x = 0.2·x
Amount spent on the bag = 20 + 0.2·x
Ratio of the cost of the wallet to the cost of the pair of shoes = 5:6
Therefore;
Cost of the pair of shoes = (6/5)×(0.2·x)
Therefore;
x - 0.2·x - (20 + 0.2·x) - (6/5) ×(0.2·x) = 844
0.36·x - 20 = 844
x = (844 + 20)/0.36 = 2400
Tony's monthly salary, x = $2400(b) The amount Tony spends on the pair of shoes = (6/5) × (0.2·x)
(6/5) × (0.2·x) = (6/5) × (2/10) × x = (12/50)·x = (6/25)·x

The taxable income in marginal tax rates for 2016 is $44964.
What is marginal tax rate?
The amount of additional tax paid for each new dollar of income received is known as the marginal tax rate. Total taxes paid divided by total income earned is the average tax rate. With a marginal tax rate of 10%, tax would be deducted from the following dollar of income at a rate of 10%.Gross income = $88000
Adjustments = $2000
Deductions interest = $27000
Property taxes = $4036
Charitable contribution = $2000
Taxable income = 88000 - (2000 + 27000 + 4036 + 2000)
= 88000 - 35036

Indigo launches a toy rocket from a platform. The height of the rocket in feet is given by h(t)=-16t² + 80t + 96 where t represents the time in seconds after launch. What is the rocket's greatest height?
The calculated value of the rocket's greatest height is 196 feet
Calculating the rocket's greatest height?From the question, we have the following parameters that can be used in our computation:
height function, h(t) =-16t² + 80t + 96
So, we have
h(t) =-16t² + 80t + 96
The maximum value of t is calculated as
t = -b/2a
So, we have
t = -80/(2 * -16)
Evaluate
t = 2.5
The rocket's greatest height is at t = 2.5
So, we have
h(2.5) =-16(2.5)² + 80(2.5) + 96
Evaluate
h(2.5) = 196
Hence, the rocket's greatest height is 196 feet

The factors of y =x³-4x²-17x+60x are (x−3), (x−5) and (x+4)
What is Polynomial?An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.
Given:
y =x³-4x²-17x+60x
Let us assume that the factors are
(x−a), (x−b) and (x- c)
So, if x is either equal to a or b or c, y=0
and a⋅ b⋅ c=−60, which means a or b and c are factors of 60.
Thus, which factor of 60 (such as 2, 3, 5, 6, 10 etc.) makes y=0.
It is given that (x−3) is a factor of y
and, When we divide y by (x−3), we get x²−x−20
Similarly x=5 makes x²−x−20 equal and Dividing x2−x−20 by (x−5), we get (x+4)
Hence, the factors of y =x³-4x²-17x+60x are (x−3), (x−5) and (x+4)

What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
They need at least 100 pieces of sushi
Sofia had ordered and paid for 24 pieces of sushi already
Sushi comes in rolls
Each roll=12 pieces at $8
R=additional rolls that Sofia orders
Additional sushi= Needed sushi - ordered sushi
=100-24
=76 pieces of sushi
Each roll has 12 pieces
76/12=6.33
Sofia has to order in rolls
So, she will order 7 more rolls of sushi of 12 pieces each
12*7=84 pieces
Recall, that they needed at least 100 pieces, so the number of pieces could be more than 100
If Sofia orders 84 pieces + the already ordered 24 pieces

Answer:
x^3y^2√xy
Step-by-step explanation:
First, you calculate what's in the square root. x^2 becomes x and y^4 becomes y^2.
Then you distribute the 1/2 to the x^5 and the y so they become x^5/2 and y^1/2.
Next, you combine the like terms. x and x^5/2 becomes x^7/2. y^2 and y^1/2 become y^5/2.
So you have x^7/2 y^5/2
To get rid of the 2 on the bottom of the exponents you square root both variables.
So you get √x^7 y^5 (square rooted x^7 and y^5)
Simplify the square rooted problem to x^3 y^2 √xy
You get x to the third power y to the second power and square rooted xy.
