Answer:
-18
Step-by-step explanation:
-5 + 10 = 5
5 - (-2) = 7
7 - 24 = -17
-17 - 1 = -18
So given x=-1, you can substitute it for x in the second equation.
-8(-1)+y=14
y+8=14
y=6
So the solution is (-1,6)
Answer:
Step-by-step explanation:
Use synthetic division to answer this. If the remainder is zero, then we can safely assume the divisor (x + 7) is a factor of the polynomial f(x)= x^3-3x^2+2x-8.
We use -7 as the divisor in synth. div. This comes from the factor (x + 7):
-7 / 1 3 2 -8
-7 28 -210
-------------------------
1 -4 30 -218
Here, the remainder is -218, not zero, so no, (x+7) is not a factor of f(x)= x^3-3x^2+2x-8.
The answer is 26 its a combinatio0n problem
