Glenn swam 2 laps every morning for 7 day. in addition to the laps he swam each morning, he swam 3 laps with his friends on tuesday and thursday. write the expression that show the number of laps he swam during the week. evaluate the expression to find the total number of laps he swam that week.

Expression = 2 × 7 + 3 + 3

Evaluation of the expression = 20

Step-by-step explanation:

Number of laps Glenn swam every morning = 2

Number of days for which he swam these laps = 7 days

⇒ Number of laps swam in a week = 2 × 7

Number of laps swam with his friend on Tuesday = 3

Number of laps swam with his friend on Thursday = 3

So, Expression that show the number of laps he swam during the week = 2 × 7 + 3 + 3

By evaluating the above expression, the total number of laps he swam that week = 14 + 3 + 3 = 20 laps

(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.
