Answer:
-4.
Step-by-step explanation:
2x^2 - 5xy - y^3
= 2(-3)^2 - 5(-3)(-2) - (-2)^3
= 2*9 - 5(-3)(-2) - (-8)
= 18 -5*6+ 8
= 18 - 30 + 8
= -12 + 8
= -4.
W/4-5=4
w/-1=4
write it so that the w is fractioned over the -1
w=-4
There are 59 integer solutions
Such questions are best solved by writing cases and calculating the total number of cases. So beginning with
1) x = -3. The possible combinations are as follows:-
-3 2 13
-3 3 12
-3 4 11
-3 5 10
-3 6 9
-3 7 8
-3 8 7
-3 9 6
-3 10 5
-3 11 4
10 combinations
2) x = -2
-2 2 12
through
-2 11 3
10 combinations
3) x = -1
-1 2 11
through
-1 10 3
9 combinations
4) x = 0
0 2 10
through
0 9 3
8 combinations
as we can see from the pattern at x =1 we get 7 combinations, at x =2 we get 6 combinations, at x=3 we get 5 combinations and at x =4 we get 5 combinations.
Thus total number of combinations 4+5+6+7+8+9+10+10 = 59 integer solution.
