Answer: Option C

Step-by-step explanation:
Whenever we have a main function f(x) and we want to transform the graph of f(x) by moving it vertically then we apply the transformation:

If
then the graph of k(x) will be the graph of f(x) displaced vertically b units down.
If
then the graph of k(x) will be the graph of f(x) displaced vertically b units upwards.
In this case we have

We know that this function has its vertex in point (0,0).
Then, to move its vertex 7 units down we apply the transformation:
.
Then the function k(x) that will have its vertex 7 units below f(x) is

Answer: 2
Step-by-step explanation: five times 2 is 10 plus 10 would equal 20
Answer:
6 be because 2×3 =6 so B it will be the given answer
Let, the length = l
Width = l/2
Area = l * w = l * l/2 = l²/2
So, Your Final Answer would be A = l²/2
Hope this helps!
Answer:
37.5
Step-by-step explanation:
50+160=210.
210 is a 31.25% increase from 160
Multiply 120 by 1.3125 to get 157.5
subtract 120 from 157.5 to get a 37.5km increase or a 31.25% increase :)
