Answer:
The system has one solution: (4,1)
Step-by-step explanation:
We have the equations:
1) Y = -X + 5
2) Y = X - 3
Replace the "value" of Y of the 2nd eq into the 1st eq:
(X - 3) = -X + 5
Now let's leave X alone in one side of the iquality:
X + X = 5 + 3
2X = 8
X = 8/2
X = 4
Now, having the value of X, replace it into any of the aquations, let's use the 2nd:
Y = X - 3
Y = 4 -3
Y = 1
The ONE solution of this equations system is (4,1), which is the point in the xy plane where the two lines intersect.
Answer:
piano=instrument
Step-by-step explanation:
a instrument does not HAVE to be a piano
Answer:
4m (A)
Step-by-step explanation:
since normally you multiply everything to get volume, we can divide the things we have from volume to get missing side. 240/12 then divided by 5=4
Slope according to this information would be -1, x is your slope and there is -1 x.
