No.
-1 is x, so replace x with -1
-3 is y, so replace y with -3
-3(-1) + 2(-3) = -6
5(-1) + (-3) = -8
Answer: 6.71
Explanation:
1) The absolute value of a complex number a + bi is √ [ (a)² + (b)²]
2) The given number - 3 - 6i is equivalent to (-3) + (-6)i, so you see that a = -3 and b = - 6.
3) Therefore, the absolute value is √ [ (-3)² + (-6)² ] = √ [ 9 + 36] = √(45) ≈ 6.708 ≈ 6.71
Answer:
Tim has -8 points.
Step-by-step explanation:
15 - 23
Another way to solve for this is reversing the order the numbers are shown:
23 - 15
Just remember the answer will be negative because Tim is losing more points than he originally had.
-8
