The answer is 41, because I just took the quiz and that was the correct answer :)
A function is an equation or graph where each x value only has one y value. In the first image you can use the vertical line test. Take your pencil and lay it on the paper vertically. Move it across the graph. Basically if an x value has multiple y value it is not a function. The first image is not a function because all x values past zero have multiple y values for each x value. In the second image it is not A because in A the x value of 2 has a y value of 1 and 8. It is not B because the 5 has a y value of 3 and 7. It’s is not D because of the 5 again. It is C because all x values are unique.
Hope that helps
Answer:
(f+g)(x) = 60x + 400
Step-by-step explanation:
Given :
Amount in account A:
f(x) = 20x + 100
Amount in account B :
g(x) = 40x + 300
Total amount in Account A and B:
f(x) + g(x) = (20x + 100) + (40x + 300)
(f+g)(x) = (20x + 40x) + (100 + 300)
(f+g)(x) = 60x + 400
Answer:
didn't give clear instructions on what to do. I just assumed you add them. answer is down below. :)
Step-by-step explanation:
if ur supposed to add them then
1. 1/8 + 8/8 + 3/8 = 12/8 = 1 1/2
2. 1/4 + 2/4 + 1/4 = 4/4 = 1
3. 1/8 + 8/8 + 4/8 = 1 5/8
4. 1/4 + 1/4 + 2/4 = 4/4 = 1
5. 1/4 + 1/4 + 1/4 + 1/4 = 1
If this is multiple choice im gonna say C
