If the equation is given in factored form and the roots are real, then you can identify the x-coordinate of the vertex by averaging the 2 root values. For example, if the roots are -2 and 5, the x-coord. of the vertex is (-2+5)/2, or 3/2.
Once you have this x value, subst. the value into the given equation to calculate y. Then write the vertex as (x,y).
Answer:
94.5%
Step-by-step explanation:
Percent decrease can be represented as
[original price] * percentage = [new price]
When trying to find the percentage, you can manipulate the equation by dividing both sides by the original price to get:
percentage = [new price] / [original price]
In this case, this is represented by 192300/203400, or 94.5%
Answer: 45 cats
Step-by-step explanation: since you got 30 dogs. 2x15= 30 so to get the number of cats do 3x 15= 45cats
You can distribute the q to both terms to get
Total number of friends = 3
Let the fare be = $ J
As it is equally divided, each friend has to pay 
amount
Angela paid $5 additional as tip so her share is 
Hence,Angela paid $ in total.
