Slope -3/4, through (-2,4)
exis [7]

Answer:

I assume you want the equation for the line in y=mx+b form, if not, you can just transfer this form to standard or intercept. y=(-3/4)x+2.5

Step-by-step explanation:

Since you have the slope and a point, plug in the points to the equation y=9-3/4)x+b to get 4=(-3/4)(-2)+b and solve.

The length of a rectangle is five less than its width. The area of the rectangle is 84 square feet. Write a quadratic equation i
salantis [7]

<u>Given</u>:

The length of a rectangle is 5 less than its width.

The area of the rectangle is 84 square feet.

We need to determine the quadratic equation in standard form that represents the area of the rectangle.

<u>Dimensions of the rectangle:</u>

Let l denote the length of the rectangle.

Let w denote the width of the rectangle.

Since, it is given that the length is 5 less than its width, it can be written as,

l=5-w and w=w

<u>Area of the rectangle:</u>

The area of the rectangle can be determined using the formula,

A=length \times width

Substituting A = 84, l=5-w and w=w, we get

84=(5-w)\times w

84=5w-w^2

Adding both sides of the equation by w², we have;

w^2+84=5w

Subtracting by 5w on both sides, we get;

w^2-5w+84=0

Thus, the quadratic equation in standard form for the area of the rectangle is w^2-5w+84=0

there are 15 rafts available for people to use on the adventure river ride. each raft holds 12 people. the park runs this ride 3
3241004551 [841]

540 people can ride the wild river in 1 hour if all of the rafts are used and each raft is full

<u>Solution:</u>

Given, There are 15 rafts available for people to use on the adventure river ride.  

Each raft holds 12 people.  

Then, total people capacity over all rafts = 15 x 12 = 180 people.

The park runs this ride 3 times each hour.  

We have to find how many people can ride the wild river in 1 hour if all of the rafts are used and each raft is full?

Then, <em>total people count who take ride = number of rides x number of people per ride </em>

= 3 x 180  = 540

Hence, 540 people can take ride in 1 hour.
