Answer: it’s the third graph
Answer: Choice A) y - 10 = 2(x - 3)
============================================================
Explanation:
We can rule out choices C and D because this diagonal line has a positive slope (as it moves uphill when moving to the right).
So m = 2 must be the slope.
---------
Recall that
y - y1 = m(x - x1)
represents the point slope form of a linear equation.
The point shown on this graph is (3,10) meaning that x1 = 3 and y1 = 10 pair up together.
So,
y - y1 = m(x - x1)
y - 10 = 2(x - 3)
which points to <u>choice A</u> as the final answer
Answer:
See below.
Step-by-step explanation:
So we have the two functions:
And we want to find:
1)
Recall that:
is the same as:
Thus, we can substitute g(x):
And substitute that into f(x):
Distribute:
Subtract and simplify:
Thus:
2)
Similarly:
Substitute f(x):
Substitute:
Distribute:
Simplify:
Therefore:
