Think about what relation and function are.
Relation: can have many outputs and one input
Function: One output or one input
D because you have to distribute the twelve to complete the equation
120/2=60 (sum of both lengths)
4x+4=60
4x=56
x=14
length=46
width=14
The perpendicular line will have the x and y coefficients swapped and one of them negated. We can write the desired line as
9(x -6) -3(y -4) = 0
where the coordinates of the point of interest are (6, 4).
Dividing by 3, this is
3(x -6) -(y -4) = 0
3x -y = 14
An equation for the line of interest is ...
3x -y = 14
Answer:
30 dollars
Step-by-step explanation:
20% times 25
0.20 times 25= 5
25 + 5= 30
