A Cooper is working two summer jobs, making $19 per hour
lifeguarding and making $10 per hour clearing tables. In a
given week, he can work no more than 14 total hours and must
earn a minimum of $180. Also, he must work a minimum of 9
hours lifeguarding and no more than 3 hours clearing tables. If
X represents the number of hours lifeguarding and y
represents the number of hours clearing tables, write and solve
a system of inequalities graphically and determine one
possible solution.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

i think is g(1)=-1.

hope that i can

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
