Cody wants to go on his senior class trip. he finds a job that pays $7 per hour and he also mows
lawns for $9 an hour. he needs to earn $693 to pay for the trip, excluding spending money.
write an inequality describing cody's goal in terms of hours at his job, x, and hours
mowing lawns, y

7x + 4y < 693

Step-by-step explanation:

7 × 8 = 56 while 4 × 9 is 36, 56+36= 92 and 92 < 693 thus why the inequality is true.

(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.
