Mathematics

posledela4 years ago
4 0

Answer:

No

Step-by-step explanation:

An equation is proportional only if it goes through the origin, meaning the if you plug in 0 for x, you should get 0 for y. In this case plugging in 0 for x gives us 2 for y, meaning it is not proportional.

Answer:

<h2>20 ft, 48 ft, 52 ft</h2>

Step-by-step explanation:

The side lengths of ΔEFG are:

5 ft, 12 ft and 13 ft.

The scale factor: s = 4

All sides of the ΔKLM are four times longer than the sides of the ΔKLM.

Therefore the side lengths of KLM are:

5 ft · 4 = 20 ft

12 ft · 4 = 48 ft

13 ft · 4 = 52 ft

Using the graph, choose the correct formula for the function g.
serious [3.7K]
The graph scale is 0.5.
g(x) is 3 units lower than f(x). How do we find this?
A isn't correct because then g(x) would be 1 <em>above</em> f(x).
C isn't correct either because that would mean that g(x) is f(x) moved 1 over to the left.
D isn't correct because that would mean g(x) is f(x) moved 3 to the right.
B is correct because it means that g(x) is f(x) moved down 3 units.
I got B, but it is always helpful to double check work. Hope this helps!
