What is the rate of change of the line through (2,3) and (3,8)?

Mathematics
1 answer:
Luda [366]1 year ago
8 0

The rate of change of a line is regarded as the slope/ gradient (m) of the line

The slope/ gradient (m) of the line moving through points (x₁,y₁) and (x₂,y₂) is given as

\begin{gathered} \text{slope (m)=}\frac{y_2-y_1}{x_2-x_1} \\ \text{Where x}_1=2,y_1=3_{} \\ \text{and x}_{2=}3,y_2=8 \end{gathered}

On substituting the above values in the formula above we will have the slope to be

\begin{gathered} \text{Slope (m)=}\frac{8-3}{3-2} \\ \text{slope (m)=5/1} \\ \text{slope (m)=5} \end{gathered}

Therefore,

The rate of change of the line through (2,3) and (3,8) is 5

Identify the property used in the first five steps to solve the equation 2(x – 5) - 6x= -22
USPshnik [31]
<span>To answer this question, you need to multiply the number inside the bracket first. Then you can move the number to the right side of the equal sign and keep the x on the left side of the equal sign. The step would be like this

2(x – 5) - 6x= -22
(2x - 10) - 6x = -22
2x - 6x  = -22 +10
-4x= -12
x= -12/-4
x=3</span>

Riley has a farm on a rectangular piece of land that is 200200200 meters wide. This area is divided into two parts: A square are
777dan777 [17]

Answer:

The inequality that models the situation for her to have money to save is

7L² > 3(200L - L²)

On simplifying and solving,

L > 60 meters

Step-by-step explanation:

The length of her farm = L meters

The farm where she grows avocados is of square dimension

Area of the farm = L × L = L²

The piece of land is 200 m wide.

Total area of the piece of land = 200 × L = (200L) m²

If the area of her farm = L²

Area of the side where she lives will be

(Total area of the land) - (Area of the farm)

= (200L - L²)

= L(200 - L)

Every week, Riley spends $3 per square meter on the area where she lives, and earns $7 per square meter from the area where she grows avocados.

Total amount she earns from the side she grows the avocados = 7 × L² = 7L²

Total amount she spends on the side where she lives = 3 × (200L - L²) = 3(200L - L²)

For her to save money, the amount she earns must be greater than the amount she spends, hence the inequality had to be

(Amount she earns) > (Amount she spends)

7L² > 3(200L - L²)

To simplify,

7L² > 3L(200 - L)

Since L is always positive, we can divide both sides by L

7L > 3(200 - L)

7L > 600 - 3L

10L > 600

L > 60 meters

Hope this Helps!!!

The volume of a cube is given by s9 and the total surface area of a cube is given by 632, where s is the side length of the cube
Mariana [72]

Answer:

Surface area of a cube = side * side * 6

632 = side * side * 6

side^2 = 632/6

side^2 = 105.3333333333

side = 10.2632028789

********************************************

For a 5 inch side

volume = 5 * 5 * 5

= 125 cubic inches

surface area = 5 * 5 * 6

surface area = 150 square inches
