Answer:
= 6 typists
Step-by-step explanation:
Well, 2 can type 2 in 2 mins,
So, 1 can type 2 in 4 mins.
So, 1 can type 18 in 36 mins.
So, 2 can type 18 in 18 mins.
So, 6 can type 18 in 6 mins.
0.4 x + 3.9 = 5.7
hope 0.4 x = 5.78 - 3.9
0.4x = 1.88
x = 1.88/0.4
x = 4.7
8+7d
So forest you combine like terms
4+4=8
There are no longer any like terms so your finished product is 8+7d
Root:(1/2, 0)
Domain: x∈R
Range: y∈R
Vertical intercept: (0, 1)
