Answer:
2. h(x)=11/(x–1)
Step-by-step explanation:
since m(x)=(x+5)/(x–1)
then the denominator can't equal zero
so x can't equal 1
so the domain is R–{1}
same goes with h(x)=11/(x–1)
as they have the same denominator
Answer:
nio
Step-by-step explanation:
Just put the coefients in to a matrix
1x-6y-3z=4
-2x+0y-3z=-8
-2x+2y-3z=-14
mulstiply 2nd row by -1 and add to 3rd
divde last row by 2
multiply 2rd row by 6 and add to top one
multiply 1st row by -1 and add to 2nd
divide 2nd row by -3
mulstiply 2nd row by -1 and add to 1st row
divide 1st row by -3
rerange
x=-2
y=-3
z=4
(x,y,z)
(-2,-3,4)
