Does it tell you what (x) stands for
If o<span>n a coordinate grid, Ming's house is located 2 blocks to the right and (I suppose also 2) blocks up from (0. 0), then the ordered pair that describes the location of Ming's house is (2,2) (moving right 2 units from some point you have to add 2 units to the x-coordinate of the point from which you are moving and moving up 2 units from this point you have to add 2 units to y-coordinate of the point from which you are moving up).

If Joe's house is located 3 blocks to the right and 2 blocks down from Ming's house, then the ordered pair that describes the location of Ming's house is (2+3,2-2), that is (5,0) <span><span>(moving right 3 units from some point you have to add 3 units to
the x-coordinate of the point from which you are moving and moving down 2 units
from the point you have to substract 2 units from y-coordinate of the point from which you are moving down)</span>.</span>
Answer:
18
Step-by-step explanation:
-3 + 80 ÷ 8 -5 · (-1) ⇒ -3 + 10 + 5 ⇒ 18
Answer:


x(0)=20,y(0)=5
Step-by-step explanation:
We are given that
Tank A contains water=80 gallons
x(0)=20,y(0)=5
Tank B contains water=30 gallons
Rate=4 gallon/min
Concentration of salt is pumped into tank=0.5 pound /gallon of water
Solution pumped from tank A to tank B at the rate=6 gallons/min
Solution pumped from tank B to tank A at the rate=2gallon/min
Solution from tank B is pumped out of the system at the rate=4 gallon/min
We have to find the DE at time t
For x
Rate in=
Rate in=
Rate out=
Rate out=3x/40[/tex]
Rate in-Rate out


For y
Rate in=
Rate in=3/40x
Rate out=
Rate out=y/5
Rate in-Rate out
