hi! hope this helps!
Answer: (9, -3), (1, -1), (0, 0), and (4, 2)
<u>Step-by-step explanation:</u>
Inverse is when the x's and y's are swapped:
The given points are: {(-3, 9), (-1, 1), (0, 0), (2, 4)}
The inverse points are: {(9, -3), (1, -1), (0, 0), (4, 2)}
Answer:
x=151/64 y=9/8 z=-51/32
Step-by-step explanation:
2x+2y+5z- (2x-y+z)=-1-2
3y+4z=-3
2x+2y+5z- (2x+4y-3z)=-1-14
-2y+8z=-15
We have two equations 3y+4z=-3 and -2y+8z=-15 (We get it due to elimination method)
3y+4z=-3 (2)
-2y+8z=-15 (-3)
6y+8z=-6
6y-24z=45
(6y+8z)- (6y-24z)= -6-45
32z=-51
z=-51/32
3y-204/32=-3
3y= -96/32+204/32
3y=108/32
y=36/32=9/8
2x+2*9/8+5*(-51/32)=-1
2x+9/4-255/32=-1
2x+72/32-255/32=-1
2x-183/32=-32/32
2x=151/32
x=151/64
