4/2 because 4/2=2 that is an integer
Answer:
Lisa is 5 years old
Step-by-step explanation:
we can make an equation like
4x=15+x
X can represent Lisa’s current age
Now just solve for X
3x=15
x=5
And we can check
If Lisa is 5 years old now
In 15 years she would be 20
And 20 is 4 times as 5 which Is her current age
So Lisa is 5 years old now.
Answer: y= 3/5x+1
Step-by-step explanation: if you want to check if its perpendicular go on Desmos graphing calculator on goolge and plug both equations:)
Answer:
The nth term in the sequence is given by the equation:

Step-by-step explanation:
Arranging a table for n and nth:
![\left[\begin{array}{ccc}n&nth\\1&1\\2&3\\2&16\\4&125\\5&1296\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dn%26nth%5C%5C1%261%5C%5C2%263%5C%5C2%2616%5C%5C4%26125%5C%5C5%261296%5Cend%7Barray%7D%5Cright%5D)
It is easier to notice that 16 and 125 result from the second power of 4 and the third of 5, respectively, which are one number below their respective position. That is why we can deduce that the base of the power is n+1.
For n=2, the base n+1 results in 3, which matches the nth term for n=2. Since 3 is the result of 3 to the power of 1, 16 is 4 to the power of 2, and 125 is 5 to the power of 3, all the powers are one number behind n, so the power is given by n-1, giving the equation:

Outliers are like outcasts of the group
Which number is farthest away from the average?
1-5 seems to be average
Solution: 25 is the outlier
