Answer:
D
Step-by-step explanation:
Because you are adding to it so it would be a positive
342.5 because you add all of them together then divide
Answer:
MK = 14
Step-by-step explanation:
MK = ML + LK , substitute values
4x - 2 = 8 + x + 2
4x - 2 = x + 10 ( subtract x from both sides )
3x - 2 = 10 ( add 2 to both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Thus
MK = 4x - 2 = 4(4) - 2 = 16 - 2 = 14
Answer:
a = 60
Step-by-step explanation:
90 + 30 = 120
120 - 180 = 60
Answer:
The equation of line L is

Step-by-step explanation:
Assuming we want to find the equation of line L.
The equation of line M is

and it passes through (-4,-4). This line was obtained after a dilation of line M by a scale factor of 4.5.
The slope of both lines are the same.
Therefore line L also has slope

We need to obtain the y-intercept of line L. We divide the y-intercept of line M by 4.5 to get that of line L.


The equation of line L is of the form:

We substitute to get;
