Answer:
x = -36, y = 6, z = -6
Step-by-step explanation:
The requirement x/z = -z means x = -z².
The requirement x/y = z means x = yz.
These two requirements together mean yz = -z², or y = -z.
The requirements that z/2 and z/3 are integers mean that z is a multiple of 2·3 = 6. The smallest magnitude non-zero multiple is z=-6 (since we also require z < -z).
Using z=-6, we have x = -z² = -36; y = -(-6) = 6.
For some positive integer n, ...
... x = -36n², y = 6n, z = -6n.
Answer:
y=1/7 x +22
Step-by-step explanation:
y=mx+c
M is the same as parallel
Put the numbers in to find c
y=1/7x+c
21=-1+c
22=c
Answer:
18.84
Step-by-step explanation:
Arc length = 2πr x central angle/360
2 x 3.14 x 9 x 120/360 = 18.84
Answer:
- The total Minutes of the Inside tasks.-F (Fish)
- The total Minutes of the Outside tasks.-G+D (Garden and Dog)
- The total Minutes of the tasks involving animals.-D+F (Dog and fish)
- The total Minutes of the tasks not involving animals.-G (Garden
Step-by-step explanation:
D is the number of minutes it takes to walk his dog
G is the number of minutes it takes to water the garden
F is the number of minutes it takes to feed his fish.
We are required to match these situations to their respective expressions:
<u>Situation</u>
- The total Minutes of the Inside tasks.
- The total Minutes of the Outside tasks.
- The total Minutes of the tasks involving animals.
- The total Minutes of the tasks not involving animals.
