Answer:

y = -3x + 6

Step-by-step explanation:

Slope-intercept form:

y = mx + b

m (slope) = $\frac{-6}{2}$ or -3

b (y-intercept, or where the line crosses the y-axis) = 6

y = -3x + 6

Sally and her husband Jim left their house at the same time traveling in the same direction. Sally drove at 55mph and Jim drove

romanna [79]

Answer:

It will take 10 hours.

Step-by-step explanation:

We know distance = rate * time

Sally's rate = 55

Jim's rate = 65

We want Jim to be 100 miles ahead of Sally

The time will always be the same.

d =Sally's distance

Sally

d = 55t

Jim

d+100 = 65 t

We know have 2 equations with 2 unknowns. Substitute d= 55t into Jim's equations

55t + 100 = 65t

Subtract 55t from both sides.

55t-55t + 100 = 65t-55t

100 = 10t

divide each side by 10

100/10 = 10t/10

10 = t

A water and sprinkle our sins water out in a circular pattern how many feet away can it spread water if the area formed by the w

ludmilkaskok [199]

Answer:

11 feet away.

Step-by-step explanation:

Given:

A water and sprinkle our sins water out in a circular pattern

Area formed by the watering pattern is 379.94 square feet

To find:

How many feet away can it spread water means we have to find distance from the middle point to the last end of circular pattern of water sprinkling (radius of a circle) = ?

solution:

By using ,Area of a circle = $\pi r^{2}$

Area of a circle = 379.94 square feet (given)

$\pi r^{2}$ = $379.94$

$3.14\times r^{2} = 379.94\\$

Dividing both side by 3.14

$r^{2} = \frac{379.94}{3.14} = 121$

Taking square root both side

$r = \sqrt[2]{11\times11}$ (Taking common)

$r = 11$

Therefore, radius = 11

Thus, it can spread water 11 feet away.
