The graph that represents the system of inequalities is the graph attached below.
How to Determine the Graph of a System of Inequalities?The graph that would represent the system of inequalities must be two lines that intersect each other and have the exact slope and y-intercept of each of the lines on the graph.
Determine the slope and y-intercept of each of the inequalities, and also determine their boundary lines based on which inequality sign they have.
The line that represents the inequality, y ≥ ½x + 1, will be a solid line that has a slope of ½, and a y-intercept of 1.
The second line that represents the inequality, y ≥ -x - 2, will be a dashed line that has a slope of 1, and a y-intercept of -2.
Therefore, the graph that represents the features stated above for both lines is shown in the diagram below.

Step-by-step explanation:
two debt payments, the first for $800 due today and the second for $600 due in nine months with interest at 10.5% compound monthly, are to be settled by a payment of $800 six months from now and a final payment in 24 months. Determine the size of the final payment if money is now worth 9.5% compounded quarterly.
Answers
Given:
First payment = $800 due today
Second payment = $600 in 9 months
Interest rate = 10.5% compounded monthly
The interest is to be settled in a payment of $800 in 6 months and a final payment in 24 months.
Let's determine the final payment if the money is now worth 9.5% compounded quarterly.
Apply the compound interest formula:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]Let x represent the initial amount of debt.
Thus, we have the equation:
[tex]\begin{gathered} (x-800)(1+\frac{0.105}{12})^{12\ast\frac{9}{12}}=600 \\ \\ (x-800)(1.00875)^9=600 \\ \\ (x-800)(1.08156)=600 \\ \\ x-800=\frac{600}{1.08156} \\ \\ x=1340.44 \end{gathered}[/tex]For the amount due in six months, we have:
[tex]\begin{gathered} A=1340.44(1+\frac{0.095}{4})^{4\ast\frac{6}{12}}_{} \\ \\ A=1340.44(1.02375)^2 \\ \\ A=1404.87 \end{gathered}[/tex]Hence, the amount which is due after 6 months will be:
$1404.87 - $800 = $604.87
Now, let's find the payment due in 24 months.
Number of months remaining = 24 - 6 = 18 months.
Hence, we have:
[tex]\begin{gathered} A=604.87(1+\frac{0.095}{4})^{4\ast\frac{18}{12}} \\ \\ A=604.87(1.02375)^6 \\ \\ A=696.35 \end{gathered}[/tex]Therefore, the final payment if the money is now worth 9.5% compounded quarterly is $696.35

To simplify the expressions you have to combine the like terms.
This means that you'll solve the operations between the terms that have the same variables, for example x + 2x=3x
Or the terms that have no variables and are only numbers, for example 4+5=9
a. The expression is
[tex]4x+3x[/tex]Both terms have the same variable "x", so you can add them together. To do so, add the coefficients, i.e. the numbers that are being multiplied by x
[tex]4x+3x=(4+3)x=7x[/tex]And you get that the simplified expression is 7x
b. The expression is
[tex]3x+5x-1[/tex]In this expression you have two types of terms, the x-related terms and one constant. In this case you have to solve the operation for the x-related terms together and leave the constant as it is
[tex](3x+5x)-1=(3+5)x-1=8x-1[/tex]The simplified expression is 8x-1

What is the value of x?
Answers
Answer: x = 50
Step-by-step explanation:
The two angles are opposite each other, meaning that they are equivalent.
So, we can set them equal to each other and then solve for x.
2(x + 10) = 3x - 30
2x + 20 = 3x -30
x = 50
Answer:
x = 50
Step-by-step explanation:
Since the two angles are opposite each other, you know that they are equal.
Set both equations equal to each other to isolate x:
2(x + 10) = 3x - 30
Distribute 2 on the left side
2x + 20 = 3x - 30
Subtract 2x from both sides
20 = x - 30
Add 30 to both sides
50 = x

Answers
Let
x -----> pounds of one kind of nuts ($2.00 per pound)
y ----> pounds of other kind of nuts ($2.90 per pound)
we have that
2x+2.90y=2.50(16) ------> equation 1
x+y=16-----> x=16-y -----> equation 2
solve the system of equations
substitute equation 2 in equation 1
2(16-y)+2.90y=40
solve for y
32-2y+2.90y=40
2.90y-2y=40-32
0.90y=8
y=8.89
Find out the value of x
x=16-8.89

1) 3x+2y=12
2) 3x-2y=12
3) y=3/2x+2
4) y= -2/3x+4
Answers
Answer: (1)
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals. So, since the slope of the given line is 2/3, the slope of the line we want to find is -3/2.
Rearranging equations 1 and 2 into slope intercept form,
[tex]3x+2y=12 \implies 2y=-3x+12 \implies y=-\frac{3}{2}x+6\\\\3x-2y=12 \implies 2y-3x=-12 \implies 2y=3x-12 \implies y=\frac{3}{2}x-6[/tex]
From this, we see that equation 1 is the answer.

Let the two numbers be represented with x and y.
Quotient of two numbers = -1:
[tex]\frac{x}{y}=-1\ldots\ldots\ldots\ldots\ldots\ldots\ldots\ldots\ldots\text{.}.(1)[/tex]Difference of two numbers = 8:
[tex]x\text{ - y = 8}\ldots\ldots\ldots\ldots\ldots\ldots\ldots\ldots\ldots\ldots\ldots(2)[/tex]From the first equation, make x the the subject.
Thus, we have:
x = -y
Substitute -y for x in equation 2:
-y - y = 8
-2y = 8
Divide both sides by -2:
[tex]\begin{gathered} \frac{-2y}{-2}=\frac{8}{-2} \\ \\ y\text{ = -4} \end{gathered}[/tex]Now, substitute -4 for y in equation 2:
x - y = 8
x - (-4) = 8
x + 4 = 8
Subtract 4 from both sides:
x + 4 - 4 = 8 - 4
x = 4
Therefore,
x = 4 and y = -4
Thus, the numbers are 4 and -4

The width of a Rectangle is 3.6 inches and the perimeter is 72 inches. What is the length of the rectangle?

The perimeter formula for a rectangle is

Evaluate the expression for the given variable.9 - k ÷ 3/4 k=2/3
Answers
We are given the following expression:
[tex]9-k\div\frac{3}{4}[/tex]We are also given that k is equal to 2/3. So, we can substitute that into the expression:
[tex]9-\frac{2}{3}\div\frac{3}{4}[/tex]Due to order of operations, we have to do the division first, and then do the subtraction. To do division with fractions, we keep the first fraction the same and take the reciprocal of the second fraction. Then, we can multiply the two fractions. Let's do that:
[tex]9-(\frac{2}{3}\div\frac{3}{4})=9-(\frac{2}{3}*\frac{4}{3})=9-\frac{8}{9}[/tex]Now, we can do the subtraction:
[tex]9-\frac{8}{9}=\frac{81}{9}-\frac{8}{9}=\frac{73}{9}[/tex]Therefore, our answer is 73/9
To draw a graph for y = 3/4x + 7, a person can draw a point at x of 0 and y of ___, a second point by going up 3 and over ___, and then draw a line through the points.
Answers
To draw a graph for y = 3/4x + 7, a person can draw a point at x of 0 and y of y = 7, a second point by going up 3 and over y = 10, and then draw a line through the points.
How to know if a point lies in the graph of a function?
All the points (and only those points) which lie on the graph of the function satisfy its equation. Thus, if a point lies on the graph of a function, then it must also satisfy the function.
Given that:
y = 3/4x + 7
At x = 0
y = 7.
Going over by 3 then,
7 + 3 = 10.
So, now y = 10
10 = 3/4x +7
3/4x = 10-7
3/4x = 3
x = 4.
Now,
To draw a graph of 3/4x + 7, a person can draw c point x of 0 and y of 7, a second point by going over 3 and up 4.
Thus, for drawing the graph for y = 3/4x + 7, a person can draw a point at x of 0 and y of 7, a second point by going over 3 and up 10 and then draw a line through the points.

Define commission.The percentage or fixed payment attached to a specific volume of sales is known as the commission rate. For illustration, a fee can be $30 for each sale or 6% of sales. The payment that is either a fixed amount or a percentage of a sale is the commission rate. When they make a sale, people in commission-based professions like insurance brokers, real estate agents, and automobile salespeople get compensated. A business pays its employees according to the revenue they bring in through a commission structure. An employee receives a commission when they conduct business or provide a service, according to the definition of commission.
