Answer:

y=\frac{1}{2}x+5

Step-by-step explanation:

Step 1: identify the slope

m=\frac{y_{2}-y_1 }{x_2-x_1} \\m=\frac{9-5}{8-0}\\m=\frac{4}{8}\\m=\frac{1}{2}

Step 2: identify the y-intercept:

b=5

Step 3: put everything into an equation:

y=\frac{1}{2}x+5

ad-work [718]

Answer:

A = 14.2/1.1 hours

B = 5.091 hours

Step-by-step explanation:

Formulate 2 simultaneous equations

5.7A + 6.8B = 111.40..........(1)

A +B =18...............................(2)

Multiply each item in (2) by 5.7 to get

5.7A + 5.7B = 97.2............(3)

subtract (1) - (3) on each side

5.7A -5.7A + 6.8B - 5.7B = 111.40 -97.2

1.1B = 14.2

B = 14.2 /1.1

to get A use equation (2)

A = 18 - B

A = 18 - 14.2/1.1 = 5.091

Anna35 [415]

Answer:

The circumference of Earth's equator is 40,080 km.

Step-by-step explanation:

Given that every 24 hours, Earth makes a full rotation around its axis, and Earth's speed of rotation at the equator is 1,670 km per hour, to determine what is the circumference of Earth's equator the following calculation must be performed:

24 x 1,670 = X

40,080 = X

Therefore, the circumference of Earth's equator is 40,080 km.

Which expression will determine the perimeter, in inches, of the rectangle? O 10 x 7 10 + 7 O (2 x 7) + (2 x 10) O 10 x 7 x 7 x
fredd [130]

Answer:

(2 * 7) + (2 * 10)

Step-by-step explanation:

The missing details in the question are:

Length = 10

Width = 7

Required

The perimeter

This is calculated as:

Perimeter = 2 * (Length + Width)

So, we have:

Perimeter = 2 * (10 + 7)

Open bracket

Perimeter = 2 * 10 + 2 * 7

Rewrite as:

Perimeter = (2 * 7) + (2 * 10)
