Answer:
A. 2.2
Step-by-step explanation:
The average rate of change between 2 x values is the total change of the y values (output values) divided by the change in the x values.Slope is special situation of that.
point 1 (x₁,y₁) → ( 2,7.5)
point 2 (x₂,y₂) → ( 18,42.5)
slope = 42.5 -7.5/18-2 =35 / 16 = 2.1875 ≈ 2.2

Answer:
A = x² + 11x + 24
Step-by-step explanation:
A = L*W
L = x+8
W = x+3
A = (x+8)(x+3)
Use any method to multiply
A = x²+8x+3x+24 combine like terms
A = x² + 11x + 24
Olga is putting a border around her triangular flower bed. She has 20 feet of border material, which will fit perfectly around the bed. She wants to make the flower bed larger by tripling the length of each of its sides. How much border material will she need in total?
Answers
Answer:
60 feet
Step-by-step explanation:
We know that a triangle has 3 sides, in this case we will call them a, b and c.
It tells us that everything is material, it measures 20, that is:
a + b + c = 20
They tell us that she wants to triple each side and to know how much material she would need in total. Then it would be:
border material need = 3 * a + 3 * b + 3 * c
common factor 3:
border material need = 3 * (a + b + c)
border material need = 3 * 20
border material need = 60
Which means that she needs a total of 60 feet of material.
Answer: She would need 60 ft of border material.
Step-by-step explanation: Olga has a triangular flower bed, which means her flower bed is three sided. Also it has been stated that she has 20 feet of border material available. which will fit perfectly around the bed. This also means the perimeter of her flower bed is 20 feet.
Assuming the sides of her flower bed are labeled as a, b and c. Then a plus b plus c would equal 20, since the perimeter is the addition of all sides of the triangle.
However, she intends to triple the length of each side of the flower bed, and that would translate into the sides being 3a, 3b and 3c respectively. This effectively triples the length of the perimeter which is shown as,
Perimeter = a + b + c
20 = a + b + c
3(20) = 3a + 3b + 3c
60 = 3a + 3b + 3c
Therefore, she is going to need more border material and that is calculated as 60 feet.

Triangle area is 42 a leg (6) times b leg (14) divided by 2
First rectangle down is 30. Use length times width
Second rectangle down is 14
Last vertical rectangle is 10
Add all areas together
Answer: 96 square feet.
Step-by-step explanation: I would assume you know how to find the area of the rectangles and you are struggling with the triangle. With triangles you take the base or the bottom and multiple it by the width and then divide by 2. In this case the base would be 14 and the width would be 6, so 14x6 is 84 and 84 divided by 2 is 42.

Answers
Answer:
(B) (1.50, 2.0)
(E) (1 and one-half, 2)
Step-by-step explanation:
On the coordinate plane
The bleachers is 1.5 units to the right and 2 units up.
1.5 units to the right indicates a positive value on the x-axis. Therefore, the bleachers x-coordinate is 1.5.
2 units up indicates a positive value on the y-axis. Therefore, the bleachers y-coordinate is 2.
Therefore, we can write the bleachers location in the (x,y) coordinate system as: (1.5,2)
The following ordered pairs shows the bleacher's location.

Greatest common factor of 50c6 and 16c5
Answers
Answer:
2c^5 is the greatest common factor.
Step-by-step explanation:
I believe you meant 50c^6 and 16c^5. c6 and c5 have no meaning. c^6 and c^5 are the sixth and fifth powers of c, respectively.
What do the two terms of 50c^6 and 16c^5 have in common? c^5 is common to both c^6 and c^5, and so, if we factor out c^5, we get:
c^5(50c + 16).
Note that 50c and 16 have only 2 as their common factor: 2(25c + 8). Thus, the final factored form of 50c^6 and 16c^5 is 2c^5(25c + 8).
2c^5 is the greatest common factor.

5(z + 1) = 3(z + 2) + 11 Solve for Z
Answers
Answer:
z=6
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
5(z + 1) = 3(z + 2) + 11
5z + 5 = 3z + 6 + 11
5z + 5 = 3z + 17
5z = 3z + 12
2z = 12
2z/2 = 12/2
z = 6
:)
Answer:
z= 6
Step-by-step explanation:
5(z + 1) = 3(z + 2) + 11
Distribute
5z+5 = 3z+6+11
Combine like terms
5z+5 = 3z+17
Subtract 3z from each side
5z+5-3z = 3z-3z+17
2z+5 = 17
Subtract 5 from each side
2z+5-5 = 17-5
2z = 12
Divide each side by 2
2z/2 =12/2
z = 6

Answers
Answer:
The number 9 is greater than 1 and less than 10, while its factors are 1, 3 and 9, therefore it is a counter example to the statement.
Step-by-step explanation:
There are four odd numbers between 1 and 10, they are: 3, 5, 7 and 9. Let's check the factors for each of them.
For 3:
[tex]\frac{3}{1} = 3\\\frac{3}{3} = 1[/tex]
Therefore 3 is not a counter example to the statement, because it behaves as stated.
For 5:
[tex]\frac{5}{1} = 5\\\frac{5}{5} = 1[/tex]
Therefore 5 is not a counter example to the statement, because it behaves as stated.
For 7:
[tex]\frac{7}{1} = 7\\\frac{7}{7} = 1[/tex]
Therefore 7 is not a counter example to the statement, because it behaves as stated.
For 9:
[tex]\frac{9}{1} = 9\\\frac{9}{3} = 3\\\frac{9}{9} = 1\\[/tex]
Therefore 9 is a counter example to the statement, since it can be divided by 1, 3 and 9.

Select the correct answer. The owner of a sporting goods store gathered data about the numbers of men’s, women’s and children’s bicycles sold each month. She used a graphing tool to organize the data in different scatter plots and found these lines of best fit: The relationship between the numbers of men’s, x, and women’s, y, bicycles sold is modeled by the equation y = 0.95x + 0.83, and the correlation coefficient for the data is 0.791. The relationship between the numbers of men’s, x, and children’s, y, bicycles sold is modeled by the equation y = 0.87x + 0.98, and the correlation coefficient for the data is 0.564. The relationship between the numbers of children’s, x, and women’s, y, bicycles sold is modeled by the equation y = 0.73x + 0.91, and the correlation coefficient for the data is 0.945.

A. the line modeling the numbers of men’s and women’s bicycles sold

Answers
Answer:
Lol I know this is old but for the people who search this up, it has to be C.)
Step-by-step explanation:
the reason i think it's C. is because it says that the correlation is 0.945 which is the strongest out of the rest so therefore it has to be more reliable. Thats my guess tho. Educated guess as teacher call it.
The line of best fit which gives the most reliable predictions is, the line modeling the numbers of children’s and women’s bicycles sold, the correct option is C.
What is the Correlation Coefficient?Correlation coefficient is the value which depicts the linear interdependence of two variables.
Its value lies in between -1 to 1.
The scatter data and the line for the best fit is:
The relationship between
numbers of men’s, x, and women’s, y, bicycles sold is modeled by the equationy = 0.95x + 0.83,
The Correlation coefficient is 0.791.
numbers of men’s, x, and children’s, y, bicycles sold is modeled by the equationy = 0.87x + 0.98
The correlation coefficient is 0.564.
numbers of children’s, x, and women’s, y, bicycles sold is modeled by the equationy = 0.73x + 0.91
The correlation coefficient is 0.945.
The correlation coefficient for the plot numbers of children’s, x, and women’s, y, bicycles sold is 0.945, which shows a strong relationship between the variables and is the most reliable prediction, the correct option is C.

The secant- secant angle PRS is half the measure of the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] (PD - QS) = 50 ( multiply both sides by 2 )
PD - QS = 100, that is
12x + 8 - (4x + 4) = 100
12x + 8 - 4x - 4 = 100
8x + 4 = 100 ( subtract 4 from both sides )
8x = 96 ( divide both sides by 8 )
x = 12
Thus
arc PD = 12(12) + 8 = 144 + 8 = 152°
arc QS = 4(12) + 4 = 48 + 4 = 52°

Answers
Answer:
Step-by-step explanation:
If [tex]A =\pi xy[/tex], then π, x, and y are all multiplied together. Multiplication is undone by division, so we will divide away the πx to solve for y:
[tex]\frac{A}{\pi x}=y[/tex] which is your last option.
Here, we are required to find an equivalent equation solved for y if the area, a is given by;
a = πxy
An equivalent equation solved for y is;
y = a ÷ (πx)
To find an equivalent equation solved for y,
We have to make y the subject of the formula in;
a = πxy.
Therefore, by dividing both sides of the equation by πx, so that y is left alone on the right hand side.
Therefore, y = a ÷ (πx).
