Answer:
-2x+3y =1.......(1)
y=3x-9........(2)
Now,
putting the value of y in equation (1),
-2x+3(3x-9)=1
or,-2x+9x-27=1
or,7x-27=1
or,7x=28
x= 4
Now putting the value of X in equation (2),
y=3×4-9
= 12-9
=3
(x,y)=(4,3)
Answer:
(0 + m)/2, (0 + n)/2.
Step-by-step explanation:
The x coordinate of the midpoint must be halfway between the x coordinates of A and B, and the y coordinate must be found in the same way.
So the midpoint is (0 + m)/2, (0 + n)/2.
Answer:
Exact Form:
f=-5/3
Decimal Form:
f= -1.6
Mixed Number form:

Step-by-step explanation:
Solve for f by simplifying both sides of the equation , then isolating the variable .
Exact Form:
f=-5/3
Decimal Form:
f= -1.6
Mixed Number form:
f= -1 2/3
Answer:
8 students
