(-9x²-2x) - (-9x²-3x) = (-9x²-2x) +(9x²+3x) = -9x²-2x+9x²+3x = (-9x²+9x²)+(-2x+3x) = x
Answer:
A
Step-by-step explanation:
The domain of sin x and cos x is [ - 1, 1]
For 2x then the multiply by 2
Answer:
g(0)=4^0 = 1
g(1) = 4^1 = 4
g(2) = 4^2 = 16
Average :
(1+4+16)/3
=(5+16)/3
=21/3
= 7
Take a sum, divide by 3 because the counted datas are 3.
Answer:
Step-by-step explanation:
Well, the ratio of yellow beads to blue beads is 4:5. The best way I think is to guess and check multiplying the ratio by integers. You need between 15 and 20.
4 : 5 ( = 9 too little )
8 : 10 ( = 18 just right)
12 : 15 ( = 27 too much)
So per necklace, 8 yellow beads and 10 blue beads would be needed.
I hope this helps :-)
