Answer #2-f(x)=2/3x+4
Answer #3-Undefined
Answer #4-f(x)= -1/5x+2
Function notation means that instead of y=mx+b, your equation will be f(x)=mx+b. F(x) and y are the same thing, and are interchangeable. However, when asking for the equation in function notation, f(x)=mx+b is how the equation is to be written.
F(x)=y
M=slope
X=variable
B=y-intercept
Let’s start with the first image. To find slope, you always use for formula rise/run. Seeing as there is no movement in the graph (values are neither increasing or decreasing), the slope is 0. Let’s add that into the equation.
f(x)=0x+b
Now let’s find b. B is where the line intersects on the y-axis on the graph. Here it is-4. Let’s add that in now.
f(x)=0x-4
Let’s move onto the second image. We see that the line intersects the y-axis at 4. Let’s add that in.
f(x)=mx+4
Now let’s find the slope. We’ll look at points (-6,0) and (0,4) to find the difference going up/down over left/right. This would be 2/3. Let’s add that into the equation
f(x)=2/3x+4
Lets move onto the third image. Much like image 1, there the values here are neither increasing or decreasing. But, this line is vertical, so the slope is undefined. That would be the answer for #3
Let’s finally do number 4. The line intersects at 2, so let’s fill that in for b now.
f(x)=mx+2
The values in the graph are negative, so m will be negative as well. Let’s add that in.
f(x)=-mx+2
Let’s find slope now. Looking at points (0,2) and (10,0), I see that the difference in rise/run is 2/10. This simplifies to 1/5. Let’s add that in
f(x)= -1/5x+2
These are your answers! Hope this helps comment below for more questions :)

How many 3/4 cup servings are in 12 cups of cherries?
Answers
Answer:
16 serving.
Step-by-step explanation:
Given: 3/4 cup servings.
Now, computing the number of serving in 12 cups of cherries.
Using unitary method to solve.
∴ Number of serving= [tex]total\ cups \times number\ of\ serving\ per\ cup[/tex]
Number of serving in one cup is [tex]\frac{4}{3}[/tex]
Number of serving in 12 cups = [tex]12\times \frac{4}{3} = 16 \ serving[/tex]
Number of serving in 12 cups= [tex]16\ serving[/tex]
∴ There are 16 serving is possible in 12 cups of cherries.
Final answer:
To calculate the number of 3/4 cup servings in 12 cups of cherries, divide 12 by 3/4, which equals 16 servings.
Explanation:
To determine how many 3/4 cup servings are in 12 cups of cherries, we can divide the total number of cups by the size of one serving.
First, we express the serving size and the total amount in the same units: 3/4 cup and 12 cups.
Next, we divide the total amount of cherries by the serving size: 12 cups ÷ 3/4 cup.
To perform the division, we can multiply 12 by the reciprocal of 3/4, which is 4/3 (12 × 4/3 = 16).
The result is that there are 16 servings of 3/4 cup in 12 cups of cherries.
Determine the y-intercept of x 12 + y 3 = 2
Answers
The y-intercept of [tex]\(12x + y^3 = 2\) is at \((0, \sqrt[3]{2})\).[/tex]
To find the y-intercept of the equation [tex]\(12x + y^3 = 2\)[/tex], we first need to understand what the y-intercept represents. The y-intercept is the point where the graph intersects the y-axis, which means the x-coordinate of this point is 0.
To find the y-intercept, we set [tex]\(x = 0\)[/tex] in the equation and solve for y:
[tex]\[12(0) + y^3 = 2\][/tex]
[tex]\[y^3 = 2\][/tex]
To solve for y, we take the cube root of both sides:
[tex]\[y = \sqrt[3]{2}\][/tex]
So, the y-intercept of the equation is [tex]\((0, \sqrt[3]{2})\).[/tex]
Coordinates of centroid of a triangle with vertices of (0,1) (2,6) (7,2)
Answers
Answer:
The centroid is located at (3,3)
Step-by-step explanation:
Centroid Of A Triangle
The centroid of a triangle is the point where its three medians intersect. It is also the center of gravity of the triangle. The medians are lines that go from each vertex to the midpoint of the opposite side.
Given A(ax,by), B(bx,by), C(cx,cy) the points of the vertices, then the coordinates of the centroid [tex]P(x_c,y_c)[/tex] are
[tex]\displaystyle x_c=\frac{ax+bx+cx}{3}[/tex]
[tex]\displaystyle y_c=\frac{ay+by+cy}{3}[/tex]
The vertices are (0,1) (2,6) (7,2), thus
[tex]\displaystyle x_c=\frac{0+2+7}{3}=3[/tex]
[tex]\displaystyle y_c=\frac{1+6+2}{3}=3[/tex]
The centroid is located at (3,3)
The coordinates of centroid are (3,3)
Step-by-step explanation:
The coordinates of centroid of a triangle are calculated by finding average of x-coordinates of vertices and the average of y-coordinates of vertices.
Given vertices are:
(0,1) (2,6) (7,2)
So,
x-coordinate of centroid:
[tex]x = \frac{0+2+7}{3}\\=\frac{9}{3}\\= 3[/tex]
y-coordinate of centroid:
[tex]y = \frac{1+6+2}{3}\\=\frac{9}{3}\\= 3[/tex]
Hence,
The coordinates of centroid are (3,3)

Linda owns 4 shares of a certain stock. Yesterday the total value of her shares went down by 32 dollars. What was the change in value for each share?
Answers
Answer:
The value of each share decreased by $8.
Step-by-step explanation:
Number of shares of a certain stock Linda owned = 4
Total value of shares went down by = $32
So find the change in value of each share.
Solution:
Let the total value of each share in dollars be = [tex]x[/tex]
Value of 4 shares in dollars will be = [tex]4x[/tex]
The total value of shares went down by $32
So, new value of 4 shares = [tex]4x-32[/tex]
New value of each share = [tex]\frac{New\ value\ of\ total\ shares}{4}[/tex]
⇒ [tex]\frac{4x-32}{4}[/tex]
Splitting the denominators.
⇒ [tex]\frac{4x{{4}-\frac{32}}{4}[/tex]
⇒ [tex]x-8[/tex]
Original value of each share in dollars was = [tex]x[/tex]
New value of each share in dollars = [tex]x-8[/tex]
Thus, we can see that the value of each share decreased by $8.

Answers
Answer:
C. (1/3,-7); x=1/3; translated to the right 1/3 unit and down 7 units.
Step-by-step explanation:
The function is (1/3,-7); x=1/3; translated to the right 1/3 unit and down 7 units.
What is a function?A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.
The parent function is:
g(x) = IxI
And we have:
f(x) = I6x - 2I - 7
Rearranging the function:
f(x) = 6Ix - 1/3I - 7
Then, now let's define some transformations:
If we start with g(x), a translation of N units to the right is:
f(x) = g(x - N)
if we start with g(x), a translation of N units up is:
f(x) = g(x) + N
A translation down would be:
f(x) = g(x) - N
And a vertical dilation of scale factor A is written as:
f(x) = A × g(x)
Then in this case we have:
A translation to the right of 1/3 units.
A dilation of scale factor 6.
A translation down of 7 units.
And the axis of symmetry will be when the absolute value part is equal to zero, or when
6Ix - 1/3I = 0
And that is when x = 1/3.
Therefore, the function is (1/3,-7); x=1/3; translated to the right 1/3 unit and down 7 units.

Janet charges an upfront fee of $20 plus $7.50 an hour for babysitting. Lisa does not charge an upfront fee, but charges $8.75 an hour. After how many hours will their charge be equal?
Answers
After 16 hours, the charges will be same.
Step-by-step explanation:
Given,
Janet's upfront fee = $20
Charges per hour = $7.50
Let,
x be the number of hours.
J(x) = 7.50x+20
Lisa has no upfront fee.
Charges per hour = $8.75
L(x) = 8.75x
For the charges to be equal;
J(x) = L(x)
[tex]7.50x+20=8.75x\\20=8.75x-7.50x\\20=1.25x\\1.25x=20[/tex]
Dividing both sides by 1.25
[tex]\frac{1.25x}{1.25}=\frac{20}{1.25}\\x=16[/tex]
After 16 hours, the charges will be same.

3) The expression is
[tex]n^3+3n^2+3n+1=(n+1)^3[/tex]
Where [tex](n+1)^3[/tex] is the cube of the middle integer
Step-by-step explanation:
1) Given three consecutive integers are n. n+1, and n+2
Now multiplying the three consecutive integers
[tex](n)(n+1)(n+2)=(n^2+n)(n+2)[/tex]
[tex]=n^3+2n^2+n^2+2n[/tex]
[tex]=n^3+3n^2+2n[/tex]
Therefore [tex](n)(n+1)(n+2)=n^3+3n^2+2n[/tex]
Now adding the middle integer to the result of the multiplication.
ie, adding (n+1) to the result of the multiplication [tex]n^3+3n^2+2n[/tex]
[tex](n+1)+(n^3+3n^2+2n)=n+1+n^3+3n^2+2n[/tex]
[tex]=3n+1+n^3+3n^2[/tex]
Therefore [tex](n+1)+(n^3+3n^2+2n)=n^3+3n^2+3n+1[/tex]
2) Expression is [tex]n^3+3n^2+3n+1[/tex]
Now we simplify the above expression
[tex]n^3+3n^2+3n+1=n^3+3n^2(1)+3(n)(1)^2+1^3[/tex]
[tex]=(n+1)^3[/tex] (by using [tex](a+b)^3=a^3+3a^2b+3ab^2+b^3[/tex] , Here a = n and b=1)

m = [tex]\frac{-4-8}{2+1}[/tex] = [tex]\frac{-12}{3}[/tex] = - 4 → B
Answer:
The slope of the given line is -4.
So, option (B) is correct.
Step-by-step explanation:
We know that, slope (m) of a line passing through points (x₁, y₁) and (x₂, y₂) is given by,
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Now, the given line passes through the point (-1, 8) and (2,-4).
So, (x₁, y₁) = (-1, 8) and (x₂, y₂) = (2, -4)
So, by using the above formula, we get
Slope(m) of the given line passing through (-1, 8) and (2, -4) is given by,
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{-4-8}{2-(-1)}[/tex]
[tex]\implies\;m = \frac{-12}{3}=-4[/tex]
∴The slope of the given line is -4.
Hence, option (B) is correct.
