Answer:
y = 24x + 17 20
Step-by-step explanation:
Firstly, let's say that 153 and 17 are both the y-intercepts of their respective equations, while 22 and 24 are the slope. With this we can create the following set of equations:
y = 24x + 17
y = 22x + 153
So your answer would be y = 24x + 17
Now let's find the sales answer!
Since we know that Ida made 4 more sales than Wade this week, we could say:
y = 24(x+4) + 17
y = 22x + 153
Now since we know that they earned the same amount we can do the following:
24(x+4) + 17 = 22x + 153
Simplify...
24x + 96 + 17 = 22x + 153
Simplify again:
24x + 113 = 22x + 153
subtract 22x and 113 from both sides...
2x = 40
Then:
x = 20
So this means that Wade made 20 sales this week!
So let's check if we are right:
Now that we know that x = 20, we need to plug it into Wade's equation!
y = 22(20) + 153
y = 440 + 153
y = 593
Wade made $593 this week!
To check if we are right, let's plug it into Ida's equation:
y = 24x + 113
y = 24(20) + 113
y = 480 +113
y = 593
Ida also made $593 this week!
MEANING we are right!

what is the sum?17.34 8.03+0.009
In order to add these numbers, first let's write all of them with the same number of decimal places:
17.34 = 17.340
8.03 = 8.030
0.009 = 0.009.
Then, let's add all algarisms that are in the same position in each number:
0 + 0 + 9 = 9
4 + 3 + 0 = 7
3 + 0 + 0 = 3
7 + 8 + 0 = 15 (5 plus 1 to next algarism)
1 + 0 + 0 (+ 1) = 2
So the final result is 25.379.

The management of the UNICO department store has decided to enclose a 903 ft2 area outside the building for displaying potted plants and flowers. One side will be formed by the external wall of the store, two sides will be constructed of pine boards, and the fourth side will be made of galvanized steel fencing. If the pine board fencing costs $7/running foot and the steel fencing costs $4/running foot, determine the dimensions of the enclosure that can be erected at minimum cost.
The dimensions of the enclosure that can be erected at minimum cost are 21.25 feet by 42.50 feet
How to determine the dimensions of the enclosure that guarantees the minimum costFrom the question, the given parameters are
Area = 903 square feet
Shape = rectangle
From the question, we understand that:
One side of the area would be enclosed by the external wall of the store
If the dimensions of the area are Length (L) and Width (W), then we have
Area = LW
Perimeter = 2L + W
Rewrite as
A = LW
P = 2L + W
Substitute 903 for A in A = LW
LW = 903
Make W the subject
W = 903/L
Substitute W = 903/L in P = 2L + W
P = 2L + 903/L
Differentiate the equation
So, we have
P' = 2 - 903/L²
Set to 0
2 - 903/L² = 0
So, we have
903/L² = 2
This gives
L² = 903/2
Divide
L² = 451.5
Take the square roots
L = 21.25
Substitute L = 21.25 in W = 903/L
W = 903/21.25
Evaluate
W = 42.50
Hence, the dimensions of the enclosure are 21.25 feet by 42.50 feet

8. (15 pts) Explain clearly why Graph A IS a function, while Graph B is NOT a function. (Youcan indicate where the graphs pass or fail and reference that in your explanation)
We can see two graphs and we need to determine the reason why graph A IS a function, and graph B is NOT a function.
To achieve that, we can proceed as follows:
1. A function is a relation in which for each element of the domain we have only (exactly) one element of the range.
2. The domain of a function is the values for x for which the function is defined, and the range is those values for y that result when the function takes values for x and after following the rule of the function (the values for which the function is defined).
3. To determine if a graph is a function, we can use the vertical line test. Given the above definitions, this test tells us that if a vertical line passes through a graph at more than a point, then the relation is NOT a function.
4. Now we can use the Vertical Line Test on each graph as follows:
Graph A:As we can see from the graph, the vertical line passes through only one point (one value for y associated to x). We can see that the open circle indicates that the function is not defined for the value while the solid circle indicates that the function is defined for that value.
For instance, for x = -1 the value of the function is y = 0 (and not y = -1 - see the open circle). We have a similar case for x = 1 (y = 1) (not y = 0).
Therefore, graph A IS a function.
Graph B
In this case, we can say that the vertical line passes through more than one point in most of the values. However, we can say that there are some values where the line passes through one point - from x = -3 to x = -2 (included) -, and for values greater than 2 (x>2).
However, since the vertical line test indicates that the line passes through more than a point (there are more than a value, y, for each x) then Graph B is NOT a function.
Therefore, in summary, we can say that using the method of the vertical line test, Graph A IS a function, while Graph B is NOT a function.
I need help graphing this piecewise function!
The piecewise function on the graph is,
f(x) = { 1 -3x ; if x ≤ 2
{ 4-x ; if x > 2
The graph of a piecewise function is given. The left function is defined on the interval x ≤ 2 and the right function is defined on the interval x > 2.
To find the functions we need two points on each function since both functions are straight lines.
First we will find the left function defined on x ≤ 2.
So the two points are (x₁, y₁) = (0,1) and (x₂, y₂) = (2, -5).
Now slope of the left function, m₁ = (y₂ - y₁)/(x₂ - x₁)
= -5 - 1/2 - 0
= -6/2
= -3
So the equation of the left function is,
y - y₁ = m(x-x₁)
⇒ y - 1 = -3(x-0)
⇒ y = 1 -3x
Thus the left function is f(x) = 1 -3x
Consider the right function.
The two points on the graph of the right function are (x₁, y₁) = (4,0) and (x₂, y₂) = (6, -2).
So slope of the second function, m₂ = (y₂ - y₁)/(x₂ - x₁)
= -2 - 0/6-4
= -2/2
= -1
Now equation for the right function is,
y - y₁ = m(x-x₁)
⇒ y - 0 = -1(x-4)
⇒ y = 4 -x
So the right function is f(x) = 4-x
Hence the piecewise function is,
f(x) = { 1 -3x ; if x ≤ 2
{ 4-x ; if x > 2

How does slavery and oppression of other people impact you?
Slavery and oppression of other people impact others as it brings about discrimination and fear.
What is slavery?In the olden days, slavery was so lucrative that the Mississippi River valley produced more millionaires per capita than any other region of the country. With cash crops like tobacco, cotton, and sugar cane, the southern states of America developed into the country's economic engine.
In Africa, the slave trade had a terrible impact. A culture of lawlessness and violence was encouraged by the financial incentives provided to warlords and tribes to participate in the slave trade. Economic and agricultural development in a large portion of western Africa was virtually impossible due to depopulation and a persistent fear of enslavement.

Let us make a sketch that will help us solve the question
From the image I provided, let the Height of the figure be H.
Then this means that the height of the figure H is

From the smallest triangle in the image,

[tex]\begin{gathered} \tan \theta=\frac{opposite}{\text{adjacent}} \\ \tan 27.73=\frac{3.5}{x} \\ x\times\tan 27.73=3.5 \\ x=\frac{3.5}{\tan 27.73} \\ x=6.65804m \end{gathered}[/tex]Now H becomes

The value of x in the equation given as 1/6(x - 3) = 1/3(x + 2) is 7
How to evaluate the equation?The equation is given as
1/6(x - 3) = 1/3(x + 2)
From the question, we can see that the equation is a linear equation with one variable
As a general rule: linear equations are equations that have constant average rates of change.
We start by multiplying both sides of the equation by 6
So, we have the following equation
6 * 1/6(x - 3) = 1/3(x + 2) * 6
Next, we evaluate the products
So, we have the following equation
x - 3 = 2x + 4
Next, we collect the like terms
So, we have the following equation
2x - x = 3 + 4

Step-by-step explanation:
u = US points
c = Canadian points
n = Norwegian points
u = c + 2
n = c - 4
208 = u + c + n
208 = ( c + 2 ) + c + ( c - 4 ) = 3c - 2

What are square roots?
The opposite of squaring an integer is finding its square root. The result of multiplying a number by itself yields its square value, whereas the square root of a number may be found by looking for a number that, when squared, yields the original value. It follows that a, a = b if "a" is the square root of "b." Every integer has two square roots, one of a positive value and one of a negative value because the square of any number is always a positive number. For instance, the square roots of 4 are both 2 and -2. However, the square root of a number is typically only expressed as the positive value.
The value of a number's power 1/2 is the number's square root. It is the number whose product by itself yields the original number, to put it another way. It is symbolized by the character "." The number behind the square root sign is referred to as the radicand, whereas the square root symbol itself is known as a radical.
