Answer:
Step-by-step explanation:
Given : A yoga membership costs $16 and an additional $7 per class.
To write : A linear equation modeling the cost of a yoga membership.
Solution :
A yoga membership costs $16.
An additional is $7 per class.
The $16 fee does not change.
Let x be the cost per class.
Let y is the total cost for membership.
The amount of a class =
Therefore, Resulting linear equation modeling the cost of a yoga membership is

The probability of selecting a number not divisible by 3 is: 2/3
Step-by-step explanation:
There are two methods to solve the question.
- We can find the probability of numbers not divisible by 3
- We can find the probability of numbers divisible by 3 and then find the complement of it
We will use the second method:
Given:
There are 24 slips
S = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24}
n(S) = 24
Let A be the event that the slip number is divisible by 3
Then
A = {3,6,9,12,15,18,21,24}
n(A) = 8
The probability of number divisible by 3 is:
The sum of the probability of an event's occurrence and non-occurrence is 1. So the probability of numbers divisible by 3 will be subtracted from 1 to find the probability of selecting a number not divisible by 3.
The probability of selecting a number not divisible by 3 will be:
The probability of selecting a number not divisible by 3 is: 2/3

Answer:
Step-by-step explanation:
Well to start with there is a vertex formula which is ,
Your initial equation is where
. So you would plug in your numbers
we know know that
so plug in h in
which would be (-2)^2+4(-2)+8 = 4-8+8 = 4 which would make the vertex
