Answer:
Step-by-step explanation:
Remark
This is a right angle triangle.
Proof
a^2 + b^2 = c^2
a = 3
b = 4
c = 5
3^2 + 4^2 = 5^2
9 + 16 = ? 25
25 = 25
Area
The 2 smaller legs are perpendicular to each other.
Area = 1/2 a * b
Area = 1/2 * 3 * 4
Area = 6
The first line is perpendicular, the second line is not perpendicular and not parallel , the third line is parallel to the above line and the forth line not parallel or perpendicular to the line.
<h3>How can the slope of the line be calculate?</h3>
The slope of the line is been given as −3x+5y=−15
Then
, hence the slope is 
- Slope of the first line 5x + 3y = 15 after calculation is
the slope is 
this means that the line is perpendicular to the given line
- Slope of the second line 3x + 5y = 15 after calculation is

This means that the line is not perpendicular and not parallel
- Slope of the Third line -3x + 5y = 15 can be calculated as

This means that the line is parallel to the above line.
- Slope of the first line 3x + 5y = 15 after calculation is

This means that the line is not parallel or perpendicular to the line

Answer:
size because when a figure is squeezed, it shrinks and changes the size
Answer:
No, they are not.
Step-by-step explanation:
The easiest way to find a function on a graph is by finding if any points share the same x value. All of these do, so none are functions.
