The curves of the labor market are illustrations of demand and supply, and the curves are all linear functions
4.1: The graph of the curves of the labor marketThe equations are given as:
D = 36 - 2W
S₁ = 9 + W ---- domestic (i.e. without immigrants)
S₂ = 10 + 2W ---- total (i.e. including immigrants)
See attachment for the graph
4.2: The equilibrium wage rate before immigrationThis is the point of intersection between the curves of S₁ and D.
From the graph, we have:
(W, D) = (9,18)
Hence, the equilibrium wage rate before immigration is $9, and the number of workers that would be hired is 18
4.3: The equilibrium wage rate after immigrationThis is the point of intersection between the curves of S₂ and D.
From the graph, we have:
(W, D) = (6.5,23)
Hence, the equilibrium wage rate after immigration is $6.5, and the number of workers that would be hired is 23
4.3.1: Number of domestic workers hiredSubstitute 6.5 for W in S₁ = 9 + W
S₁ = 9 + 6.5
S₁ = 15.5
Remove decimal
S₁ = 16
Hence, the number of domestic workers that would be hired is 16
4.3.1: Number of immigrants hiredSubstitute 6.5 for W in S₂ = 10 + 2W
S₂ = 10 + 2 * 6.5
S₂ = 23
Subtract S₁ = 16 from S₂ = 23
Immigrants = 23 - 16
Immigrants = 7
Hence, the number of immigrants that would be hired is 7

If f(x) = 2x^3- 2x^2 - 14x + 30 and x + 3 is a factor of f(x), then find all of
the zeros of f(x) algebraically.
Answers
Answer:
Step-by-step explanation:
First confirm that x = 1 is one of the zeros.
f(1) = 2(1)^3 - 14(1)^2 + 38(1) - 26
f(1) = 2 - 14 + 38 - 26
f(1) = -12 + 38 = + 26
f(1) = 26 - 26
f(1) = 0
=========================
next perform a long division
x -1 || 2x^3 - 14x^2 + 38x - 26 || 2x^2 - 12x + 26
2x^3 - 2x^2
===========
-12x^2 + 28x
-12x^2 +12x
==========
26x -26
26x - 26
========
0
Now you can factor 2x^2 - 12x + 26
2(x^2 - 6x + 13)
The discriminate of the quadratic is negative. (36 - 4*1*13) = - 16
So you are going to get a complex result.

Answer:
a) - y = 30°,x = 70°
b)- y = 105°,x = 75°
c)- x = 25°
d)- x = 116°
Step-by-step explanation:
a) =
80 + 70 + y = 180 (co-interior angles)
or, y = 180 - 150
so, y = 30°
Now,
x = 70° (alternate angles)
b) =
y + 75 = 180° (co-interior)
(y = angle which is supplement to 75)
y = 180° - 75°
so, y = 105°
Now,
x + y = 180° (co-interior angles)
or, x = 180° - 105°
so, x = 75°
c)=
180° - 5x = 55° (corresponding angles)
or, 5x = 180° - 55°
or, 5x = 125°
or, x = 125°/5
so, x = 25°
d)=
64° + x = 180° (co-interior angles)
x = 180° - 64°

Bartering was an early way that people exchanged goods.
☆Explanation:In earlier times money was not there,so people used to follow a system in exchange of goods. This system was known as barter system. In barter system commodities were exchanged against commodities. ¤ Example:-Let's imagine a situation between "A" and "B". Suppose "A" wants rice and have sugar. On the other hand "B" has rice and he wants sugar. So,there will be exchange between "A" and "B" where "A" will give sugar to "B" and "B" will give rice to "A".

Find the equation of a line perpendicular to y=−6 that contains the point (1,3). Write the equation in slope-intercept form
Answers
Answer:
x=1
Step-by-step explanation:
Hi there!
We are given that a line is perpendicular to y = -6 and passes through the point (1, 3)
We want to write the equation of this line in slope-intercept form
Slope-intercept form is y=mx+b, where m is the slope and b is the value of y at the y intercept, hence the name
First, we need to find the slope (m) of the line
Remember that we were given that the line is perpendicular to y = -6
Perpendicular lines have slopes that multiply to get -1
The slope of y = -6 is 0; therefore, to find the slope of this line, we can do the following equation
0m=1
Divide both sides by 0
m = 1/0
This answer is undefined - therefore, the line has an undefined slope
If this is the case, then it means the line is a vertical line
A vertical line is written as x=k, where k is the value of x at the x intercept. It can't be written in slope-intercept form.
This value is also the value of x at every point that lies on such line - in this case, as given by the point (1, 3) , this value is 1
So substitute 1 as k.
x = 1
This is the line of the equation.
Hope this helps!

How much would the investment be worth?
As the function for interest is already given to us, also,
The principal amount, P = $7,000
The rate of Interest, r = 3%
Time period, t = 5 years
Compounded semiannually, n = 2
Substitute the values,
Hence, the worth of the investment after 5 years at an interest of 3% is $8,123.79.
Answer:
Hello! Let's find the value of Janel's investment after 8 years. In the formula we're using, P will represent the principal amount, r will represent the rate of interest, and t will represent time. Since the interest is compounded semi-annually (twice a year), n = 2. Finally, A represents the value of the investment after t (8 years).
Substitute these values into the formula:
[tex]A = P(1 + \frac{r}{n} )^{nt}[/tex]
[tex]A = 7000(1+\frac{0.03}{2} )^{2*8}[/tex]
Simplify the equation:
[tex]A = 8882.89883357[/tex]
Round this number to the nearest hundredth:
[tex]A = 8882.90[/tex]
The correct answer is B. 8,882.90.

Step-by-step explanation:
You have to find the total area of all the shapes and subtract the unshaded.
(9 + 17) * 8 / 2, formula
26 * 4 = 104
Then find the unshaded part
9 * 8 / 2
9 * 4
= 36
104 - 36 = 68
Answer:
68
Step-by-step explanation:
The formula of a trapezoid is [tex]A = \frac{a+b}{2} h[/tex]
Use the values given in the equation:
[tex]A = \frac{17+9}{2} *8[/tex]
A = 13*8
A=104 (This the area of the overal trapezoid)
To find the area of the inner unshaded triangle, simply multiply 9 (Base) times height (8) * 1/2 to get 36
Then subtract 36 from 104 and you get 68
