Answer:
12
Step-by-step explanation:
for g(3) replace x with 3 and for f(4) since f(x) is a constant function the value won't change so you put 2 then add both functions up
g(3) = 3^2 + 1 ➡ 10
f(4)= 2
10 + 2 = 12
Answer: A. inverse variation; xy = 20
ANSWER
Step-by-step explanation: Brainly
B) xy=20
Inverse because it is of the form y=k/x, intuitively you can see that as x increases y decreases, hence "inverse variation".

Answer:
Option B is correct
Inverse variation , xy = 20
Step-by-step explanation:
Inverse variation states:
If
then the equation is in the form of:
or
xy = k ....[1]
As per the statement:
Given the data:
x : 2 4 8 12
y : 10 5 5/2 5/3
Let any value of x and y to find k:
x = 4 and y = 5
Substitute in [1] we have;
⇒20 = k
or
k = 20
then we get;
xy = 20
Check:
Substitute x = 12 and y = 5/3
⇒ true.
Therefore, the the data in the table represent a inverse variation and an equation to model the data in the table is, xy = 20
5.) 48 Minutes (Note: you must complete the drawing)
6.) 2/3 of the children have red or brown hair.
7.) Abdul spent $4.28
8.) No, because if you add up the distance from the home to the store and back you get 1/2 mile and if you add from home to the library and back you get 1/5 of a mile, which when you add them together you get 7/10 which is not equal to a mile.

Answer:
Relation A is not a function.
Step-by-step explanation:
By definition, a function must have a single unique y-value output for each x value. In Relation A the same y-value 1 appears for 3 different x-values.
