Answer: A
48+ 36 = 84
84/4 = 21 groups
there are 21 groups of 4 balloons
The ratio would be 44 / 22 = 2 / 1 or we could say 2:1
Answer:
p, m, n.
Step-by-step explanation:
It is given that,

Here, p is the name of the function and its variable is m which is independent.
Independent variable : Whose value does not depend on another variable.
Dependent variable : whose value depends on the another variable.
Since the value of n depends on the value of p(m) which is a function of m, therefore n is a dependent variable which depends on the variable m.
∴ If n = p(m), p is the function name, m is the independent variable, and n is the dependent variable.
1.
g(x) = 3 - x^2
g(-2) = 3 - (-2)^2 = 3 - 4 = -1
f(x) = 5x + 4
g(g(-2)) = f(-1) = 5(-1) + 4 = -1
2.
f(x) = 5x + 4
f(-2) = 5(-2) + 4 = -10 + 4 = -6
g(x) = 3 - x^2
g(f(-2)) = g(-6) = 3 - (-6)^2 = 3 - 36 = -33
