54. We need to find the value of the expression
In order to do so, we can use the following definition for exponentials:
In this problem, we have x = 12. Thus, we can evaluate the expression as follows:
Let's see another way to find the same result.
Notice that when a number has the positive exponent n, it means that we have a product of n factors of that number. For example:
On the other hand, when the exponent is negative, by definition, the minus sign tells us to find the inverse of that number. For example:
Also, notice that 1 to any exponent equals 1. For example:
So, we can write:
Therefore, the value of the given expression is 12.
Answer:
Age of Cathy = 19
Step-by-step explanation:
Find:
Sum of their ages = 54
Assume;
Age of Andrea = x
Age of Beth = x + 1
Age of Cathy = x + 2
Sum of their ages = x + x + 1 + x + 2
54 = 3 x + 3
3 x = 51
x = 17
Age of Cathy = x + 2
Age of Cathy = 17 + 2
Age of Cathy = 19
To answer this we will divide 32 (total elephants) by 4 (times more).
32 ÷ 4 = 8
Check your work:-
8 × 4 = 32
We were right! :)
So, there were 32 elephants.
Hope I helped ya!!!!!!!!!!
Slope intercept form would be y=9/16x-9/16
