25
Step-by-step explanation:
65+A=90
A=90-65=25
Answer:
(-infinity, 1) ∪ (1,3) ∪ (3, +infinity)
Step-by-step explanation:
Here only the 2nd function, g(x) = x^2 - 4x + 3, affects the domain. Recognizing that division by zero is undefined, we set g(x) = 0 anyway and solve for x: x^2 - 4x + 3 = 0 = (x -3 )(x - 1) = 0. Thus, x cannot have either value 3 or 1. Using this info, we write the domain as follows:
(-infinity, 1) ∪ (1,3) ∪ (3, +infinity). This is Answer #3.
Solving for variables is easy as all we must do is isolate the variable and simplify. In this case, to isolate the variable, we simply need to divide "n" by 10 (because the "n" is being multiplied by 10).
10n=40
/10 /10
n=4
Using the math above, we can see that n=4.
