Answer:

The answer is 9.

Step-by-step explanation:

If you substitute a and b with the numbers given, the equation you'll have to solve is: 2(5)+2-3.

2(5)=10 and 2-3=-1

Once you subtract 10-1, the answer would be 9.

PLEASE HELP ASAP!! Also, please explain how to solve. Thank you

By evaluating the given relation, we conclude that the correct options are A, D, and G.

<h3>How to check if the points are on the graph?</h3>

We have the relation:

k = ∛(V/7)

Such that this relation gives us pairs of the form (V, k).

So, to check if the points belong to the graph of the relation, we need to evaluate the points on the given relation and see if the relation is true.

A) (0, 0) gives:

Evaluating in V = 0

k = ∛(0/7) = 0

So this point belongs.

B) (1, 1) gives:

k= ∛(1/7) = 0.52

So we have the point (1, 0.52) and the point  (1, 1)  then does not belong to the graph.

We just need to do that for all the points, evaluate V and see if k gives the same value as in the point.

With this method, we will see that the correct options are:

D) (7, 1)

k= ∛(7/7) = 1

G) (56, 2)

k= ∛(56/7)  =   ∛(8) = 2
