C.
if you multiply the 4 on each numbers inside of the parentheses then you’ll get ‘20c-8d’
Answer:
1/8 cup
Step-by-step explanation:
x = 7/8 - 1/4 - 1/2
x = 7/8 - 2/8 - 4/8
x = 1/8
Answer:
Unlikely
Step-by-step explanation:
The probability of picking a number divisible by 5 is 2/12 or 1/6. So its pretty unlikely.
Answer:
4x10^12
Step-by-step explanation:
So firstly, foil (x-8)(x-2): 
Next, remember that the vertex lies on the axis of symmetry, and the equation to find the axis of symmetry is
(a = x^2 coefficient, b = x coefficient). Solve for the axis of symmetry as such:

So now that we know that the axis of symmetry is x = 5, we also know that's the vertex's x-coordinate (since the vertex falls on the axis of symmetry). Now plug in 5 for x in the original equation to solve for f(5):

So putting it together, the vertex of this equation is (5,-9).
