Answer:
y = 32
Step-by-step explanation:
(2y + 3) + 23 + 90 = 180
2y = 64
y = 32
Answer:
One-fourth times 32
Step-by-step explanation:
Yes, I know...31.3 rounded is 31, not 32. But it's closer than any other number.
Answer:
This is so easy
Let me explain:
first lets find out (f+g)(x)=-x+3x+5+x^2+2x=
x^2+4x+5 this is the equation of a parabola because we have x^2
so only the first graph shows us a parabola
which remains the right one.
Remark
Many calculators have a key that will do this in one step. Mine is one of them. So let's start with the answer and then we'll do it the long way.
9C3 = 84. You put it into your calculator as 9 2nF nCr 3 =
Solution

3*4*7 = 84 which is what you set out to show.
I would be happy to help but it seems there are no pictures attached to answer from.
