​ y=−8x−3 x+y=7 ​ Is (3,4)(3,4)left parenthesis, 3, comma, 4, right parenthesis a solution of the system? Choose 1 Choose 1 (Choice A) A Yes (Choice B) B No

Given:

The system of equation is

To find:

Whether (3,4) is a solution of the given system or not.

Solution:

We have,

         ...(i)

           ...(ii)

Putting the value of y in (ii) from (i), we get

Divide both sides by -7.

Putting in (i), we get

So, the only solution of the given system is .

Hence, (3,4) cannot be a solution of given system, Hence the correct option is B.

hey there!

12 is twice as much as 6 because 6 goes into 12 2 times.

since the rabbit is twice as tall, we should multiply the weight of the first rabbit, 0.25, by 2.

0.25 x 2 = 0.5

therefore, the 12 inch chocolate rabbit weighs 0.5 lb, or half a pound.

hope this !
