This is the answer 16x^2 y-6xy^2
Answer:
5.2
Step-by-step explanation:
On x sub 3.5 and on y sub 1.7
Then: (3.5) +(1.7)
3.5 +1.7
= 5.2
Answer:
(x, y) = (5, 1)
Step-by-step explanation:
To <em>eliminate</em> x, you can double the second equation and subtract the first.
... 2(x +4y) -(2x -3y) = 2(9) -(7)
...11y = 11 . . . . . simplify
... y = 1 . . . . . . divide by 11
Using the second equation to find x, we have ...
... x + 4·1 = 9
... x = 5 . . . . . subtract 4
_____
<u>Check</u>
2·5 -3·1 = 10 -3 = 7 . . . . agrees with the first equation
(Since we used the second equation to find x, we know it will check.)
The nearest whole number would be 13 because it takes more to get to 14 and take less to go to 13 so you answer is 13
