Answer:
Solution is (2, -1)
Step-by-step explanation:
The lines cross at the point where x = 2 and y = -1.
Multiply both sides by x so that x will be in the numerator
Answer:
The polynomial f(x) = x^2 - 8x - 20
Answer:
8-3i
Step-by-step explanation:
The complex additive inverse is the number we need to add so that we get zero. It is the negative of the number.
a + bi is –(a + bi) = –a – bi.
a+bi + (-a+-bi) = a-a + bi-bi = 0
The complex additive invers of -8+3i is
-(-8+3i)
Distribute the negative
8 -3i
32, 7
0, - 1
20, 4
You just plug in the numbers and solve
