i believe it is.
Step-by-step explanation:
STEP-BY-STEP SOLUTION:
Let original price = x
New price with 10% discount from the original price = $50
( 100% - 10% )x = 50
90% of x = 50
x = ( 50 / 90% ) × 100%
x = $55.55 reciprocal
x = $55.55 ( to the nearest nickel )
There aren't any numbers that add to 24 but multiply to 9. But you can still factorise - remember, you only need to get numbers that add up to the middle number if the coefficient of y^2 is 1. That means if you just have y^2, not 2y^2 or 3y^2 or 16y^2 like we do here.
<span>16y^2+24y+9 = (4y+3)^2</span>
Answer: Part one! --- y=x^2+12x+27
Part two --- y=x^2+18x+80
Step-by-step explanation: For both of these questions, you have to work backwards to find the factors from the roots, then multiply the factors together! I know it looks like a long process, but really it's just turn around, back up, multiply and BOOM! Answer is there for. You just have to look at your signs, exponents and make sure you keep PEMDAS in order as well. All math basically requires PEMDAS. Like these questions right here that you asked! ☺
It's pretty easy but it takes a while to get a hang of it. I am still trying to get better at it as well but I am also trying to help you out!
I hope I helped you! Again! Haha! ☺
