Answer:
f(x) = 15
Step-by-step explanation:
"If f(x)= 5x + 40, what is f(x) when x = -5?"
Substitute x for -5:
f(x) = 5x + 40
f(x) = 5(-5) + 40
f(x) = -25 + 40
f(x) = 15
Not similar, since the ratio of corespondent side is not constant
suppose ∆PRQ ~ ∆MRN, then RN/RP = RM/RQ but the reality contradict
Answer:
sorry about that v but to make it shorter the answer is undefined
Step-by-step explanation:
To calculate the slope (m) use the
The 2 points here are (12 ,10) and (12 ,5)
Division by 0 is undefined , hence slope is undefined.
This is, in fact, a line parallel to the y-axis and passing through all points in the plane with an x-coordinate equal to 12.
For this reason it's equation is x = 12
A 'quick' way to note when this situation occurs is to observe that the x-coordinates of the 2 given points are equal.
