Answer:
western beach: y = -2x + 100
dunes beach : y = 5x + 20
set the equations equal to each other
-2x + 100 = 5x + 20
100 - 20 = 7x
80 = 7x
80/7 = x
x ~ 11.43 years

Hi again!
I think I already answered this question - right ?
Ok whatever - the answer and the steps are still in my head~
x^3 - 4x² + 2x + 10 = x² - 5x - 3
Again, same thing
x^3 - 4x² + 2x + 10 -x² + 5x + 3 = 0
Now factorize
(x + 1)(x² - 6x + 13) = 0
Set factor equal to 0
x + 1 = 0 or x² - 6x + 13 = 0
x = -1
The correct option is : B
A+ Guaranteed!
Answer:
4 pounds
Step-by-step explanation:
1/3 x 3 = 1
1/12 x 3 = 3/12 = 1/4
to get one whole, multiply by 4
1/4 x 4 = 1
1 x 4 = 4
What grade is this............
