Answer:

The correct option is c.

Step-by-step explanation:

We need to find a graph which is the most appropriate to describe a quantity decreasing at a steady rate.

Quantity decreasing at a steady rate means the quantity decreasing at constant rate.

If a function decreases by a constant value, then the graph of function is a straight line with a downward slope.

Only graph c represents a straight line with a downward slope.

Therefore the correct option is c.

What is an equation in point-slope form of the line that passes through (-7.1) and (-3.9)?

forsale [732]

Answer:

$y-1=2(x+7)$

Step-by-step explanation:

Point-slope form: $y-y_1=m(x-x_1)$ where a given point is $(x_1,y_1)$ and the slope is $m$

<u>1) Find the slope of the line (m)</u>

Slope = $\frac{y_2-y_1}{x_2-x_1}$ where the given points are $(x_1,y_1)$ and $(x_2,y_2)$

Plug in the points (-7,1) and (-3,9)

$= \frac{9-1}{-3-(-7)}\\= \frac{8}{-3+7}\\= \frac{8}{4}\\= 2$

Therefore, the slope of the line is 2. Plug 2 into the equation as m:

$y-y_1=2(x-x_1)$

<u>2) Plug one of the given points into the equation</u>

We plan either plug in (-7,1) or (-3,9) and it would work either way. Below you can see the equation plugging in the point (-7,1):

$y-1=2(x-(-7))\\y-1=2(x+7)$

I hope this helps!

Elly has 2 rectangular gardens. One measures 1809 cm by 2891 cm and the other measures 738 cm by 249 cm. Elly wants to put a fen

Liono4ka [1.6K]

Answer:

She needs 11374 cm to buy

Step-by-step explanation:

* Lets explain how to solve the problem

- The dimensions of the first rectangle is 1809 cm and 2891 cm

- The dimensions of the first rectangle is 738 cm and 249 cm

- Elly wants to put a fence around both

- To find the length of the fence calculate the perimeters of the two

rectangles

- The perimeter of the rectangle = 2(b + h), where b , h are the

dimensions of the rectangle

# First rectangle

∵ The dimensions are 1809 cm and 2891 cm

∵ P = 2(b + h)

∴ P = 2(1809 + 2891) = 2(4700) = 9400 cm

# Second rectangle

∵ The dimensions are 738 cm and 249 cm

∵ P = 2(b + h)

∴ P = 2(738 + 249) = 2(987) = 1974 cm

∵ The length of the fence = the sum of the perimeters of the two

rectangles

∴ The length of the fence = 9400 + 1974 = 11374 cm

* She needs 11374 cm to buy
