The solution to a system of equations is where the lines intersect, which are: A. (-2,0) C. (1, -3)
What is the Solution to a System of Equations?When a system of equations is represented on a graph, the solution to the system of equations is simply the coordinates of the points where the line of the equations intersect.
Thus, the lines intersect at (-2,0) and (1, -3). Therefore, the solution to the system of equations are: A. (-2,0) C. (1, -3)

Karen owns a seafood restaurant. She orders trout from an online retailer. Each pound of trout costs $28, and the company charges a $4 fee for shipping the order. However, if Karen orders 10 or more pounds, the trout costs only $22 per pound, but the shipping fee is $8.
Which piecewise function models the cost of x pounds of trout?
Answers
Answer:
28x + 4, 0 < x < 10
22x + 8, x ≥ 10
Step-by-step explanation:
The piece wise function models the cost of x pounds of trout will be 28x + 4, 0 < x < 10 and 22x + 8, x ≥ 10.Option A is correct.
What is a function?A connection between independent variables and the dependent variable.is defined by the function.
Given data;
Trout costs for each pound are, $28,
Shipping charges,$4
x is the number of orders
Given condition;
Karen orders 10 or more pounds, the trout costs only $22 per pound, but the shipping fee is $8.
Functions help to represent graphs and equations. A function is represented by two variables one is dependent and another one is an independent function.
The total amount is found as;
⇒No of orders × price of trout per pound + shipping charge per order
⇒28x + 4,
For condition 2 the total value is represented as;
⇒No of orders × price of trout per pound + shipping charge per order
⇒ 22x + 8
The piece wise function models the cost of x pounds of trout will be 28x + 4, 0 < x < 10 and 22x + 8, x ≥ 10.
Hence, option A is correct.

The graph represents the number of cups of flour for the number of cups of sugar in a cake recipe. Using the graph, which of the following is a correct amount of flour and sugar?
A) 2 cups of flour: 1 1/2 cups of sugar
B) 1 1/2 cups of flour: 1 cup of sugar
C) 5 cups of flour: 3 cups of sugar
D) 1 1/2 cups of flour: 2 1/4 cups of sugar
Answers
Answer: B) 1 1/2 cups of flour: 1 cup of sugar
Step-by-step explanation:
When you look carefully at the graphed line, it intersects the grid at 1 1/2 on the vertical scale for Flour and at the same point, it intersects the 1 on the horizontal scale for Sugar. That is answer B.
Answer A is a close miss! When you follow the grid line across from 2 on the vertical scale, you see that the graphed line crosses it at just a little less than 1 1/2.

1. 109
2. 29
3. 71
Step-by-step explanation:
1. since a triangle's interior angles always add up to 180, you can add 35 and 36 to get 71, then subtract that from 180 to find the third angle
2. the unnamed angle in triangle RUV is supplementary to <1.Supplementary angles are angle the add up to 180. So you can subtract 109 from 180 to find the unnamed angle. It is 71. Now you can repeat the steps in question one to find <2 in triangle RUV. You get that <2 is 29
3. Angle 3 and the unnamed angle are vertical angles. This means that they are opposite to each other and are congruent. This means that they have the same measure. Knowing that the unnamed angle is 71, we can say that angle 3 is also 71.

The domain of u(x) is the set of all real values except 0 and the domain of v(x) is the set of all real values except 2. What are the restrictions on the domain of (u circle v) (x)?

x Not-equals 0 and x cannot be any value for which u(x) Equals 2
x Not-equals 2 and x cannot be any value for which v(x) Equals 0
u(x) Not-equals 2 and v(x) Not-equals 0
Answers
Answer:
The domain would include all the real values except [tex]x = 2[/tex] and the x for which [tex]v(x) = 0[/tex].
Hence, the restrictions would be:
[tex]x\:\ne \:2[/tex]and
[tex]v\left(x\right)\:\ne \:0[/tex]Step-by-step explanation:
Given
The domain of u(x) is the set of all real values except 0.
so
domain = (-∞, 0) U (0, ∞)
The domain of v(x) is the set of all real values except 2.
so
domain = (-∞, 2) U (2, ∞)
For the function composed function (u circle v) (x), we need to apply first the function [tex]v(x)[/tex] whose argument is (x), and then the function [tex]u (v(x) )[/tex] whose argument is [tex]v(x)[/tex].
Please note that the domain of the composed function (u circle v) (x) must have to take into account the values for which both functions u(x) and v(x) are defined.
Therefore, the domain would include all the real values except [tex]x = 2[/tex] and the x for which [tex]v(x) = 0[/tex].
Hence, the restrictions would be:

Xenia has 100,000,000 people. Of this population, 25,000,000 residents are below age 16, and 10.000,000 have given up looking for work. Currently, 15,000,000 people are unemployed but are actively looking for work, and the rest are fully employed. What is the unemployment rate?
Answers
Answer: 45000
Step-by-step explanation:
The unemployment rate should be 23.1%.
The calculation is as follows;Total Labour Force = Total Population - People are Below 16 Years of Age - Unemployed People Not Looking for Work
= 100,000,000 - 25,000,000 - 10,000,000
= 65,000,000
Now
Employment Rate = Unemployed People Actively Looking For work ÷ Total Labour Force
= 15,000,000 ÷ 65,000,000
= 23.1%

Lin's Job pays $8.25 an hour plus $10 of transportation allowance ench week. She has to work at least 5 hours a work to keep the job, and can earn up to $175 per week (including the allowance) Write an Inequality for this situation
Answers
Answer:
x ≥ 5, 8.25x + 10 = 175, and x = 20 hours.
Step-by-step explanation:
Let Lin works x hours per week.
Now given that Lin’s job pays $8.25 an hour plus $10 of transportation allowance each week.
And she has to work at least 5 hours a week to $175 per week.
So, the inequality that can be written from the above condition is x ≥ 5 .......(1)
And the equation that can be written that
8.25x + 10 = 175 ....... (2)
Now, fro equation (2) we can write x = 20 hours which satisfies equation (1).
The inequality of the situation is x ≥ 5, 8.25x + 10 = 175, and x = 20 hours.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.
Let Lin work x hours per week. Now given that Lin’s job pays $8.25 an hour plus $10 of transportation allowance each week.
And she has to work at least 5 hours a week for $175 per week.
So, the inequality that can be written from the above condition is,
x ≥ 5 .......(1)
And the equation that can be written that
8.25x + 10 = 175 ....... (2)
Therefore, the inequality of the situation is x ≥ 5, 8.25x + 10 = 175, and x = 20 hours.
