If you would like to solve 16x^2 - 81 = 0, you can calculate this using the following steps:
<span>16x^2 - 81 = 0
</span>(4x - 9) * (4x + 9) = 0
1. 4x - 9 = 0 ... 4x = 9 ... x = 9/4
2. 4x + 9 = 0 ... 4x = - 9 ... x = - 9/4
The correct result would be: <span>x = 9 over 4, x = −9 over 4.</span>
what is your question lol
I see right away that 3 can be factored out of <span>15xy − 45x − 6y + 18.
The quotient is 5xy - 15x - 2y + 6, so that
</span>15xy − 45x − 6y + 18 = 3(5xy − 15x − 2y + 6) (2 factors)
<span>
or 3 [ 5x(y-1] - 2 [y-3])

Answer:
y= -50x + 400
Step-by-step explanation:
-50 miles from the place which means they are going further and further away so it is negative. And its 400 because y=mx+b the b is 400 because thats where they started. Also it said it was correct on A-p-e-x.
