All you need to know is that domain is x and range is y, like a graph.
A is the correct answer
2 + 3i + (-1) + 7i
1 + 10i
D. 2:3..
Ratios are basically fractions. Find a number that both numbers in the ration can divide into. In this case, it's 3. 18/3 is 6 and 27/3 is 9. but you're still not done, because 6/3 is 2 and 9/3 is 3
Answer:
Option C. 2x + 20 / x² + 6x – 40
Step-by-step explanation:
f(x) = x + 16 / x² + 6x – 40
g(x) = 1 / x + 10
To find f(x) + g(x), please refer to the attached photo.
It can be factored.
We need two numbers that multiply to -12 and add to -4, so are two terms would be -6 and 2.
(x - 6) (x + 2) = 0
x = 6
x = -2
