Answer:
20
Step-by-step explanation:
For the sake of the problem, let's make female workers "x" and male workers "y".
x+y<40 This equation shows that the total number of workers has a max of 40.
30x+20y<1,000 This equation shows that the total cost the manager pays ($30 to each woman, $20 to each man) has a max of $1,000.
Now you can solve for x and y.
X+y<40
-y -y
X<-y+40
Substitute -y+40 in for X in the second equation
30(-y+40)+20y<1,000
-30y+1200+20y<1,000 Distribute
-10y+1,200<1,000 Combine like terms
-10y<-200 Subtract 1,200
y>20 Divide by -10; flip the sign
Since y>20, and y=male workers, you now know that the minimum
number of male workers he should send is 20

Answer:
850 words can be typed in 17 minutes
Step-by-step explanation:
Divide 300 by 6 and multiply it by 17 and that is your answer, 850.
Answer:
The inverse of this equation would be y = 
Step-by-step explanation:
To find the inverse of any equation, start by switching the y and x values. Then solve for the new y value. That equation will be your inverse.
y = 7x^2 - 3
x = 7y^2 - 3
x + 3 = 7y^2
= y^2
= y
