Answer:

-2y

Step-by-step explanation:

Let's simplify step-by-step.

x−y−(x+y)

Distribute the Negative Sign:

=x−y+−1(x+y)

=x+−y+−1x+−1y

=x+−y+−x+−y

Combine Like Terms:

=x+−y+−x+−y

=(x+−x)+(−y+−y)

=−2y

How do you write an equation of a line that passes through (4,3) and has a slope of 2?

lana66690 [7]

Answer:

y = 2x - 5

Step-by-step explanation:

y-intercept form is y = mx + b, where m is the slope and b is the y-intercept. We know the slope is 2, so all that's left is to find the y-intercept. To do this, for every 1 we subtract from x in (4,3), we take away 2 from y because the slope is two. We keep doing this until x is zero. The remaining y-value is the y-intercept.

Alan is building a fence around his fish pond. The fish pond is in the shape of a rectangle with a length of 60 feet and a width

Assoli18 [71]

Answer:

12.50 ft per hour

Step-by-step explanation:

Given that:

Fish pond has a rectangular shape.

Length of fish pond = 60 feet

Width of fish pond = 40 feet

Total time to complete the fencing = 16 hours

To find:

Unit rate of putting the fencing around the fish pond.

Solution:

First of all, we need to find the total fencing to be put around the fish pond.

Total fencing is nothing but the perimeter of the fish pond which is of rectangular shape.

Formula for perimeter of rectangular shape is given as:

$Perimeter = 2\times (Length + Width)$

$Perimeter = 2\times (60+40)\\\Rightarrow Perimeter = 200\ ft$

Unit rate is the perimeter divided by total time taken to put the fencing around.

Therefore,

Unit rate = $\frac{200}{16} = \bold{12.5}$ feet per hour

So, the answer is 12.5 feet per hour.
