First, we should add 1 to both sides to isolate the variable:
3x = 12
Now that x is isolated, we divide by 3:
x = 4
Answer:
ithink its a or c
Step-by-step explanation:
not sure but dang what grade u in??
horizontal line: x=9
vertical line: y=3
You can plug it into the application demos to see it visually just put y=3 on one line and x=9 on the other
1 A. 5
1 B. 12.9
2. For this one, u can write any number less than 4.7, which could be 3, 2, -100, 1.21, etc.
3. For this one, u can write any number greater than (positive!) 2.6, such as 10, 30, 3.1415, etc.
hope this helps!
Answer:
They are not commutative, because f(g(x)) and g(f(x) are not equal.
Step-by-step explanation:
In order for the composition of the functions to be commutative, we must have ...
f(g(x)) ≡ g(f(x))
for all values of x.
Here, we have f(g(x)) = 1 and g(f(x)) = 2. f(g(x)) and g(f(x)) are not equal, so the composition of the functions is not commutative.
