Jamie's older brother and his three friends want to split the cost of lunch they also want to leave a 15% 20% tip how much should each person pay

See explanation

Step-by-step explanation:

Your question isn't well written but let me help out by making some assumptions.

Let's say Jamie's older brother and his three friends want to split the cost of lunch that costs $30 and they also want to leave a 20% tip. How much should each person pay?

Cost of the lunch = $30

Tip = 20% × $30 = 0.2 × $30 = $6

Total amount to be paid = $30 + $6 = $36

Since there are four people and they want to share the cost, each person would pay:

= $36 / 4

= $9

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
