Answer is:9x^2-12y^2-11x in other words D
Explanation: find all the common variables and combine. In this case since your adding adding you would add 8x^1 and x^2 to get 9x^ then add -9y^2 and -3y^2 to get -12y^2. And so on to get the rest of the problem. One tip to help make this simpler is circle one type of variable like circling all the x^2, boxing all the y^2, and underlining all the x. Hope this helps
Answer:
the answer would be no solution
Step-by-step explanation:
because, Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation
3/4y-(5/x)=0
and from there you may not do anything else.

$1.50- $0.9
=$0.6
Percent discount=
$0.6/$1.5 x 100
=40%
Check answer=
40/100 x $1.5
=0.6
$1.5- $0.6 = $0.9
(I hope this solution help!)
