Answer:
I'm sorry but what is the question?
Step-by-step explanation:
The ratio of interest can be found for collinear points by considering only one of the coordinates. Let's look at the x-coordinates.
(Tx -Mx)/(Dx -Mx) = (1-(-3))/(9-(-3)) = 4/12 = 1/3
Then the ratio of interest is MT:MD = 1:3.
Answer:
Given the function f(x) = 3x + 1, evaluation of f(a + 1) gives:
C. 3a + 4
Step-by-step explanation:
Given function:
f(x) = 3x + 1
We have to find f(a+1).
For this purpose, we will take x = a+1 and
substitute it in the function f(x) = 3x+1:
f(x) = 3x + 1
f(a+1) = 3(a+1) +1
f(a+1) = 3(a) + 3(1) +1
f(a+1) = 3a+3+1
f(a+1) = 3a + 4
So the function f(a+1) is equal to option C. 3a + 4.
Try it.
8 =? 2*8 - 4
8 =? 16 - 4
8 =? 12
8 is not a solution of the original equation
Try 4
4 = 2*4 - 4
4 = 8 - 4
4 = 4 and yes 4 works.
4 is unique. No other solution will work.
