Answer:
60≥20x+50y
Step-by-step explanation:
Let x = notebooks and y = pens (all per week)
One solution would be x ≥ 1 and y ≥ 1 as at least one per each item per week
It is not recommended that points be marked with X, let's marked with C(6,6)=(Xc,Yc)
The coordinates of the point C(Xc,Yc) which belongs to the line AB and divides line AB in a ratio m : n = 1 : 2 or m/n=1/2 are get it with following formula
Xc=(Xa+(m/n)Xb) / (1+(m/n)) and Yc=(Ya+(m/n)Yb) / (1+(m/n))
We have A(2,2)=(Xa,Ya) and B(14,14)=(Xb,Yb)
When we replace given coordinates we get
Xc=(2+(1/2)*14) / (1+(1/2)) = (2+7) /(3/2) = 9/(3/2) = (9*2)/3 = 3*2 =6 => Xc=6
Yc=(2+(1/2)*14) / (1+(1/2)) = (2+7) / (3/2) = 9/(3/2) = (9*2)/3 = 3*2 =6 => Yc=6
C(Xc,Yc)=(6,6)
Good luck!!!
If you have moved z from -1 to +1, you have moved it +2 (2 to the right). If you move z from 5 to 1 you have moved it down 4. So your rule here in coordinate form is (+2, -4). Add 2 to each of the other x coordinates and subtract 4 from each of the other y coordinates to get the new points. A(3, -1) P(0, 0) Z(1, 1)
