Y = -x^2 + x + 2
y = -x + 3
-x + 3 = -x^2 + x + 2
x^2 - x - 2 - x + 3 = 0
x^2 -2x + 1 = 0
(x - 1)(x - 1) = 0
x - 1 = 0 y = -x + 3
x = 1 y = -1 + 3
y = 2
solutions are : (1,2) , (1,2)
Answer:
Below in bold.
Step-by-step explanation:
The circumference is one dimensional so the ratio is the same as the radii,
1.5.
The areas are 2 dimensional so the ratio is 1.5^2 = 2.25.
Answer:
64
Step-by-step explanation:
5x-16+6x=10x (combine like terms)
11x-16=10x (subtract 11x)
-16= -1x (divide by -1
16 = x
Now plug 16 into 5x-16.
5(16)-16 = 80-16 = 64
