Answer:
21
Step-by-step explanation:
The x intercept is represented by the coordinate (x,0) on x axis.
So, to find the x intercept ,we need to equate y=0 in the equation 20x+70y=420
=> 20x+ 70*0=420
=> x=420/20 =21.
x intercept is (21,0).
Answer:
Y= 40
Step-by-step explanation:
I know the y equals 40 because I used
But for z and x I got stuck, so I hope I helped you a little to move forward with this problem.
YOU CAN DO THIS!!!!!
