Answer:

In order to check if the x and y value is a solution then you need to plug in your numbers for the x and why value.

Take this as an example with your solution (4,7) let's try 4x-9=y. We want to plug in the values of each variable so the new equation will look like 4(4)-9=(7). Now you want to multiply and get 16-9=7 next subtract and you get 7=7. This would be a solution for the problem.

Now we can try 3x+14=y do the same thing from last example and you'll get 3(4)-14=7 and now multiply to get 12-14=7 now subtract and you'll get -2=7 which is NOT a solution to this equation so it would become -2≠7.

5) Step-by-step solution:
Step 1 of 2
Write the numbers (other than dates) in this statement in scientific notation.
The mass of Pluto, the smallest planet, is 0.0021 times that of Earth; The mass of Jupiter, the largest planet, is 317.83 times that of earth.
The first number is 0.0021.
Now move the decimal point to the right of the first nonzero digit and count the number of places it was moved.

The original number (0.0021) was small so the exponent will be .
Therefore, the scientific notation is .
Step 2 of 2
The second number is 317.83.
Now move the decimal point to the right of the first nonzero digit and count the number of places it was moved.

The original number (317.83) was large so the exponent will be .
Therefore, the scientific notation is .

6) Simply move the decimal point 16 places to the right of where it currently is.

9.803 moved three times = 9803.
Then just add 13 zeroes (because 16 minus those first three = 13) to 9803, giving you a final result of 98030000000000000. Then if you wanted to make it pretty on your eyes with commas, it would be 98,030,000,000,000,000.
