Answer:
12/23/56
Step-by-step explanation:
Divide the amount left by the percentage left:
they sold 35%, so there is 65% remaining.
280 / 0.65 = 430.769
Round to 431
Now check:
431 x 0.35 = 150.85
Round to 151
431 - 151 = 280 left.
They originally had 431 peaches.
Simplify the expression first by the "flip and multiply" method. We end up first with:
[x(x-3)]/[x⁻¹(x+4)]
Simplifying further we have:
[x²(x-3)]/(x+4)
Solving for restriction we equate the denominator to 0:
x + 4 = 0
x = -4
x≠4 (-4 is a restriction of the expression)
Take out - 1
k(x) = -1(x^2 - 2x - 15) Now factor what's inside the brackets. The numbers you pick must add to - 2 and multiply to -15.
When you multiply to -15 you should note that one of the numbers is plus and the other is minus.
(x - )(x + ) is the way it looks.
They differ by 2 and the "largest" one is minus. That means your answer is -5 and +3
k(x) = - (x - 5)(x + 3)
Now for the zeros.
x - 5 can be a zero
x - 5 = 0
x = 5
x + 3 = 0
x = - 3
