Answer: 80
Step-by-step explanation:
Number of visitors in first week = 5
Number of visitors in second week = 10
Number of visitors in third week = 20
The common ratio here is = 10/5 = 2
The fifth term will be:
= ar^n-1
where,
a = first term = 2
r = ratio = 2
n = number of terms = 5
= 5 × 2^(5-1)
= 5 × 2^4
= 5 × 16
= 80
Answer:
y = 48/x
Step-by-step explanation:
"Inverse variation" means y is proportional to the inverse of x. If the constant of proportionality is represented by k, then ...
y = k/x
Multiplying by x, we find k to be ...
xy = k
So, the given values tell us k is ...
8·6 = k = 48
and the desired equation is ...
y = 48/x
Answer:
A
Step-by-step explanation:
y-int = -2
so the line should cross (0, -2)
Rise over run is 2/5 so go up 2, over 5 and put your dot etc...

X = $120
Hi there!
The sum of two rational numbers will always equal a rational number. Similar to adding fractions, if both denominators are the same then you can add them together. In the case of rational numbers, it is the same. Adding two of the same thing together makes the sum the same, rational.
