What is transformation on the graphs?Let the function f(x) and g(x) are two real functions.
And g (x) = f (x) + k, where k is real numbers.
Function can be sketched by shifting f (x), k units vertically.
The direction of shift can be found by the value of k:
if k > 0, the base graph shifts k units up, and
if k < 0, the base graph shifts k units down.
The function provided by the basic function f(x) and the constant
g(x) = f(x - k),
may be drawn by horizontally moving the f(x) k unit coordinates.
The shift's direction depends on the value of k. Specifically,
The base graph moves k units to the right if k > 0, and
The base graph moves k units to the left if k < 0.
The graph of y = |x+2| is a V-shaped graph centered at x = -2.
To translate this graph, we need to modify the equation to shift it up/down or left/right.
Here are the equations for each translation:
a) To shift the graph one unit up, we need to add 1 to the equation:
y = |x+2| + 1
b) To shift the graph one unit down, we need to subtract 1 from the equation:
y = |x+2| - 1
c) To shift the graph one unit to the left, we need to replace x with (x+1) in the equation (since moving left means decreasing x by 1):
y = |(x+1)+2|
Simplifying this gives:
y = |x+3|
d) To shift the graph one unit to the right, we need to replace x with (x-1) in the equation (since moving right means increasing x by 1):
y = |(x-1)+2|
Simplifying this gives:
y = |x+1|
Therefore, all the required values are given above.

Eddie purchased 15 boxes of paper clips and 7 packages of index cards for a total of $55.40. Finn bought 12 boxes of paper clips and 10 packages of index cards for $61.70. Find the cost of one box of paper clips and one package of index cards
The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95
Step-by-step explanation:
Eldora and Finn went to an office supply store together
Eldora bought 15 boxes of paper clips and 7 packages of index cards for a total cost of $55.40
Finn bought 12 boxes of paper clips and 10 packages of index cards for a total cost of $61.70
We need to find the cost of one box of paper clips and the cost of one package of index cards
Assume that the cost of one box of paper clips is $x and the cost of one package of index cards is $y
∵ x represents the cost of one box of paper clips
∵ y represents the cost of one package of index cards
∵ Eldora bought 15 boxes of paper clips and 7 packages of
index cards for a total cost of $55.40
∴ 15x + 7y = 55.4 ⇒ (1)
∵ Finn bought 12 boxes of paper clips and 10 packages of
index cards for a total cost of $61.70
∴ 12x + 10y = 61.7 ⇒ (2)
Now we have system of equations to solve it
Multiply equation (1) by -10 and equation (2) by 7 to eliminate y
∵ -10(15x) + -10(7y) = -10(55.4)
∴ -150x - 70y = -554 ⇒ (3)
∵ 7(12x) + 7(10y) = 7(61.7)
∴ 84x + 70y = 431.9 ⇒ (4)
Add equations (3) and (4)
∵ (-150x + 84x) + (-70y + 70y) = (-554 + 431.9)
∴ -66x = -122.1
- Divide both sides by -66
∴ x = 1.85
Substitute the value of x in equation (1) or (2) to find y
∵ 12(1.85) + 10y = 61.7
∴ 22.2 + 10y = 61.7
- Subtract 22.2 from both sides
∴ 10y = 39.5
- Divide both sides by 10
∴ y = 3.95
The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95

Find the area of the rug. DO NOT ROUND.
Answer:
28.26 ft²
Step-by-step explanation:
Formula
Area = πr²Given :
Diameter = 6 ft⇒ Radius = 3 ft [Diameter = 2 x Radius]Solving :
Area = 3.14 x 3 x 3Area = 3.14 x 9Area = 28.26 ft²Answer:
28.26 feet²
Step-by-step explanation:
Substitute the radius in the formula:
⇒ Area of circular rug = πr²
⇒ Area of circular rug = π(6/2)² [Diameter/2 = Radius]
Simplify the R.H.S:
⇒ Area of circular rug = π(3)²
⇒ Area of circular rug = π(9) [(3)² = 3 × 3 = 9]
Take π as 3.14 and simplify:
⇒ Area of circular rug = (3.14)(9)
⇒ Area of circular rug = 28.26 feet² (Using calculator)

Answer:
Initially, as x increases, y is constant.
Afterward, the slope of the graph of the function equals 2 for all x between x = 3 and x = 5.
The slope of the graph equals -1 for x between x = 5 and x = 9.
The greatest value of y is y = 4, and it occurs when x = 5.
Step-by-step explanation:
Initially, the graph of the function is flat. The quantity y remains constant as x increases from x = 0 to x = 3. The linear equation that corresponds to the function in that region is y = 0. The slope is m = 0 because the graph is a horizontal line. The graph of the function starts to increase starting at x = 3. The slope, rise/run, once we solve it, is equal to 2 for when x is between 3 and 5. After x = 5, y starts to decrease as x increases. The slope of the graph between x = 5 and x = 9 is -1. The maximum value of y occurs at the top of the bump in the graph. The coordinates of the top of the bump are (5,4). Therefore, the maximum value is y = 4, and it occurs when x = 5.

A custodian can clean 2 classrooms in 15 minutes. At this rate, how many classrooms can a custodian clean in 76 minutes?
Answer:
10 Classroom
Step-by-step explanation:
Since,
Custodian clean 2 classrooms in 15 minutes
Then ,
Let's see how many minutes does it takes for a custodian to clean for 1 classroom
To Find that we have to divide the given minutes by the given classroom.
15/2 = 7.5
Hence, in 7.5 minutes a custodian clean 1 classroom
Therefore:
Classroom to minutes:
1 = 7.5
2 = 15
3 = 22.5
4 = 30
5 = 37.5
6 = 45
7 = 52.5
8 = 60
9 = 67.5
10 = 75
11 = 82.5
Hence, we round to the nearest number:
which is 10 classroom in 75 minutes.
For this reason, the answer is about 10 classroom

Answer:
a) Infinite solutions = intersect at every point (2 of the same line)
m = rise/run = 3/2
b = y-intercept = (0, -3)
y = 3/2x - 3
b) No solutions = no point of intersection (parallel lines)
m = 3/2 (same slope b/c parallel)
b = (0, 2)
y = 3/2x + 2
c) One solution = one point of intersection
Solution = (4, 3)
y - y₁ = m (x - x₁)
y - 2 = m (x - 2)
m = [tex]\frac{y2-y1}{x2-x1}=\frac{3-2}{4-2} =\frac{1}{2}[/tex]
y - 2 = 1/2 (x - 2)
y = 1/2x + 1
Check to see if (4, 3) is the solution to the system:
y = 1/2x + 1
y = 3/2x - 3
1/2x + 1 = 3/2x - 3
1 = 2/2x - 3
x = 4 ✅
y = 1/2(4) + 1 = 3 ✅

Suppose the planned dimensions of a rectangular kitchen have a length-to-width ratio of 3 to 2. The length of the original kitchen is 6z feet. The original kitchen can be made larger by adding four feet to each original dimension. Write a polynomial expression that represents the floor area of the larger kitchen in square feet. Write your answer in standard form.
Answer:
150 sq. in.
Step-by-step explanation:
Because... Suppose the planned dimensions of a rectangular kitchen have a length-to-width ratio of 3 to 2. The length of the original kitchen is 6z feet. The original kitchen can be made larger by adding four feet to each original dimension. Write a polynomial expression that represents the floor area of the larger kitchen in square feet.
The polynomial expression that represents the floor area of the larger kitchen in square feet is 24z² + 40z + 16
What is Area of Rectangle?The area of Rectangle is length times of width.
The length-to-width ratio of the original rectangular kitchen is 3 to 2.
Let the width of the original kitchen "w".
Then the length of the original kitchen is length = 3/2×w
We are also told that the length of the original kitchen is 6z feet. We can use this information to solve for the width of the original kitchen:
6z = 3/2×w
w = 4z
So the width of the original kitchen is 4z feet.
To make the kitchen larger, we add four feet to each original dimension. The new length is:
length = 6z + 4 feet
width = 4z + 4 feet
Area = (6z + 4 feet) × (4z + 4 feet)
Multiplying out the terms, we get:
Area = 24z² + 40z + 16 square feet
Therefore, the polynomial expression that represents the floor area of the larger kitchen in square feet is 24z² + 40z + 16

Given is a pie chart or circle graph.
This shows the number of different colored T shirts that the Trenton's scouting group made.
Total number of T shirts = 100
Total degree of a circle = 360°
The circle is divided in to various sections with each section of different degree.
Angle measure for the purple section = 54°
Proportion of purple T shirts to the full T shirts = 54 / 360
