Answer:

The answer is part B

Step-by-step explanation:

The equation given is y = 4500 - 450p

y is the no of demand units

p is the price

let price be 1 dollar.

Therefore,

y = 4500 - 450x1

y = 4050

Now, let the price be 2 dollars.

y = 4500 - 450x2

y = 3600

Subtract the two values and the answer is 450.

This means that for each dollar increased, the no of demand units falls by 450

A rectangular yard measuring 39 ft by 67 ft is bordered (and surrounded) by a fence. Inside, a walk that is 4 ft wide goes all t

Gekata [30.6K]

The area of the walk is 784 square feet

Area is the quantity that expresses the extent of a region on the plane or on a curved surface

First, calculate the area of the rectangular yard.

Area = L x W

where A equals area, L equals length, and W equals width.

According to the stated problem:

A = 39 x 67

A = 2613 square feet <-------Area of Rectangular yard.

Now, according to the stated problem there is a walk that is 4 feet wide going all the way along the fence (Inside). "

Therefore, we have 8 feet to subtract from each of the values above (39) and (67).

That is 4 feet on each side,

A = L x W

A = 31 x 59

A = 1829 square feet <----------Area of new rectangle formed by allowing for three foot walk.

Now, subtract the area of the new rectangle formed from the area of the original area. Doing so, will give you the area of the walk, correct?

Original area = 2613 square feet

New area = 1829 square feet

Hence, the Area of WALK = 784 square feet

Which ordered pair (a,b) is a solution to the given system of linear equations.

egoroff_w [7]

Answer:

A. (-13,-3)

Step-by-step explanation:

Solve the system of two equations:

$\left\{\begin{array}{l}-2a+3b=14\\a-4b=3\end{array}\right.$

From the second equation:

$a=3+4b$

Substitute it into the first equation:

$-2(3+4b)+3b=14\\ \\-6-8b+3b=14\\ \\-8b+3b=14+6\\ \\-5b=20\\ \\5b=-20\\ \\b=-4$

So,

$a=3+4b=3+4\cdot (-4)=3-16=-13$

The solution is (-13,-4)

Rita is hiking along a trail that is 13.8 miles long. So far she has hiked along one-tenth of the trail.

vichka [17]

Rita has hiked 1.38 miles so far.

Step-by-step explanation:

Given,

Total length of the hiking trail = 13.8 miles

Distance covered by Rita so far = $\frac{1}{10}\ of\ the\ trail$

Distance covered in miles = $\frac{1}{10}*13.8$

Distance covered in miles = 1.38 miles

Rita has hiked 1.38 miles so far.
