Answer:
Solutions are (6,3) and (-2,3).
Step-by-step explanation:
From the first equation given we can write:
substituting for
in the second equation given we get


∴ y=3
Putting y=3 in the first equation we get

x-2 = ±4
Hence x=6 or x=-2.
The left hand side of the equation is a difference of two squares and may be factored out as follows,
(x - 4)(x + 4) > 0
They may be individually taken as,
x - 4 > 0 ; x > 4
x + 4 > 0 ; x < -4
Thus, the answer to this item is letter A.
Answer:
I've never had to deal with this before but I would say C


Synthetic division yields
-3 | 1 5 4 -6
. | -3 -6 6
- - - - - - - - - - - - -
. | 1 2 -2 0
which translates to

with remainder 0. Now by the quadratic formula,

and so
Answer:
0.62
Step-by-step explanation:
divide 56 by 90
