Which is the slope of the line with equation 7 x − 3 y = 21 ?

Mathematics

Rus_ich [418]3 years ago

Answer:

slope = \frac{7}{3}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 7x - 3y = 21 into this form

Subtract 7x from both sides

- 3y = - 7x + 21 ( divide all terms by - 3 )

y = \frac{7}{3} x - 7 ← in slope- intercept form

with slope m = \frac{7}{3}

Tanner cycled 8 miles in 20 minutes .What is the constant of proportionality based on the situation
solmaris [256]

The constant of proportionality based on the situation is 0.4

Step-by-step explanation:

Tanner cycled 8 miles in 20 minutes

We need to find the constant of proportionality based on the situation

1. The distance is proportion to the time, because the distance and

   the time increased together

2. If the distance d and the time is t, then d ∝ t

3. The equation of the direct proportion is d = k t, where k is the

    constant of proportionality

∵ d = k t

∵ d = 8 miles

∵ t = 20 minutes

- Substitute these values in the equation above

∴ 8 = k (20)

- Divide both sides by 20

∴ k = 0.4

The constant of proportionality based on the situation is 0.4

If a ball rotates through 110 degrees in 8 seconds, how many rotations does it make in 32 seconds
Vedmedyk [2.9K]
Hello there!

If:

110....> 8 seconds
x........32 seconds

Cross multiply

8 * x = 32 * 110

8x = 3520

x = 3520/8

x= 440

It makes 440 rotations in 32 seconds


I hope this helps!
