Answer:
the answer is 1
(-4-(-2)) divided by (-3-(-1))
Answer:
Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x3+73 f - 1 ( x ) = x 3 + 7 3 is the inverse of f(x)=3x−7 f ( x ) = 3 x - 7 .
Answer:
5 eggs are left over.
Step-by-step explanation:
Computers love this question. They have a built in command called mod which will give the answer in one line.
L = (85 + 28) mod 6: Print L
Humans have a little tougher time with it. We do it like this
Add 85 and 28 = 113
Divide by 6
113 / 6 = 18.8333333
What is left over is 0.833333333. But what does that mean, and how do you get rid of it?
Answer Number of Trays: The 18 is easily explained. He can fill 18 trays.
But we still have 0.83333333 to deal with.
The simplest way is to multiply that by 6.
6 * 0.833333333 = 5
The answer is 5
Remember
difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)
and the undistributiv propeoryt
ab-ac=a(b-c)
so we have

undistribute and factor

cancel out the one ( (u-2)/(u-2)=1)

is result
