Answer:
5
Step-by-step explanation:
60÷6 is 10
54÷6 is 9
30÷6 is 5
4/5n – 1/5 = 2/5n
Add 1/5 to both sides
4/5n = 2/5n + 1/5
Subtract 2/5n from both sides
2/5n = 1/5
Divide both sides by 2/5
n = 1/2
Answer:
substitute value of x and y as 2 and 4
y=5x-6
4= 5*2-6
4=4 so yes
Step-by-step explanation:
Answer:
c. 2
Step-by-step explanation:
As y increases 2 units as x increases 1 unit from (0, 3) to (1, 5)
the slope of the line is 2/1 = 2
We are given
f(x)=
g(x)=
\to find f o g, replace all the x in f(x) with g(x)
= Simplify by taking least common denominator and reciprocal.
Taking the least common denominator, we get
Taking reciprocal, we get
Simplifying the expression, we get
To find the domain of a composite function, we need to find the domain of f o g and the first function i.e g(x)
To find the domain of f o g, equate the denominator to 0
It means, domain is all real numbers except
Domain of g(x) is all real numbers except
combined domain is
