In case of plane, for y intercept, x and z are o .
So we will get
4(0)+5y-0=20
5y=20
Dividing both sides by 5
y = 4
So the y intercept is (0,4,0).
In second question, x intercept is 1, y intercept is -1 and z intercept is 2 .
So the correct option is the third equation , that is x-y+2z=4 .
1 bed room = 12
2 bed room = 15
68 x 15 = 1020
57 x 12 = 684
-----------
1020 + 684 = $1704 (total made)
15 two-bed room + 12 one-bed room = 27 rooms in all
Slope is -1/2
2-4/6-2=
-1/2
m=-1/2
1. irrational: √48 = 6.92820323028
2. rational: √9 = 3
3. irrational: √39 = 6.2449979984
4. rational: √289 = 14
So it’s -3 and the second one is +4
