Im pretty sure that those would be parallel lines

First, subtract 2y from the first equation. This makes:
3x=-2y-5
Next, add 5
3x+5=-2y
Finally, divide each side by two. You would do these steps because you want to find out what the slopes and y intercepts are.

-3/2x-5/2=y
y=-3/2x-5/2

Do the same thing to the other equation. You should get:

-2x+3y=-5
-2x=-3y-5
-2x+5=-3y
Finally, divide by -3 on both sides:

2/3x-5/3=y
y=2/3x-5/3

Finally, compare the two lines.

y=-3/2x-5/2
y=2/3x-5/3

The two lines are perpendicular because the slopes are total opposites from each other. One is negative and the other is positive, and the fraction on both of them is the reverse of the other. These two things are what makes the line perpendicular. For the line to be parallel, both the slopes would have to be the same thing

Consider that ΔDEF is similar to ΔGHI and the measure of ∠E is 58°. What is the measure of ∠H?
spayn [35]

Answer:

58 degrees

Step-by-step explanation:

If figures are similar to each other, it means that they have the same measures. Therefore, D has the same measure as G, E has the same measure as H, and F has the same measure as I.

Nastasia [14]

Answer:

The height of the building is 730 feet.

Step-by-step explanation:

370 x 12 = 4,440 inches

4,440 ÷ 18.5 = 240 inches

240 x 36.5 = 8,760 inches = 730 feet

A construction company uses the function f(p) where p is the number of people working on a project to model the amount of money
Jlenok [28]

Answer:

Domain of f(p) =  [0,∞), where it belongs to whole numbers only

Step-by-step explanation:

The domain is the set of all possible values of independent variable for which function is defined

As in the given function f(p), we have the independent variable p. As p is the number of people working on the project, so it means either the number of people could be 0 or it could be anything greater than 0,  like it could be equal to thousand or ten thousand, but it can not be fraction in any case.

So, the domain is set of whole numbers starting from 0.

Domain of f(p) = [0,∞)
