Answer:
10 + 5i & 10 - 5i
Step-by-step explanation:
10 + 5i is still just 10 + 5i because we treat i like it's x.
Complex conjugate if I remember correctly is like a + or - form, so I believe 10 - 5i is correct?
Hope this helped.
Answer:(1, -3).
Step-by-step explanation:
If y=2x-5 is equation (1) and 4x-y=7 is equation (2), then substitute equation (1) in equation (2):
4x - (2x - 5) = 7
4x - 2x + 5 = 7
2x = 7-5
2x = 2
x = 1
Now substitute the value of x in equation (1) to find the value of y:
y = 2 (1) - 5
y = 2 - 5
y = -3
Answer:
Step-by-step explanation:
find the difference between two percentages,Example, it's 15% - 5% = 10%. Second: Take 10 percent, and divide by 2nd percentage: 10/5 = 2. Now multiply this number by 100: 2*100 = 200%
Answer:
your answer would be .
Step-by-step explanation:
8750
Answer: x = 3
First, subtract 2 from both sides of the equation to get 10x = 30.
Then divide both sides by 10 to isolate x and you get x = 3.
