Answer:
third option: (x+3) / √x+2
Step-by-step explanation:
f(x) = √x+2 g(x) = (x² + 1) / x
(g·f)(x) = g(f(x)) = ((√x+2)² + 1) / √x+2
==> (x+2+1) / √x+2
==> (x+3) / √x+2
Answer:
40
Step-by-step explanation:
First we need to subtract the 50 students enrolled in English class.
150 - 50 = 100
Next, let's add the mathematics students and the physics students.
80 + 60 = 140
Then we subtract the total amount of mathematics and physics students by the total number of students.
140 - 100 = 40
Therefore, there are 40 students who take both mathematics and physics.
Answer:
y = -2
Step-by-step explanation:
10 -5y = 20 { subtract 10 from both sides}
-5y = 20 - 10
-5y = 10 {Divide both sides by (-5) }
y = 10/-5
y = -2
