Answer:
Answer
d) 2 – i
Explanation
f(x) = x³ – 2x²
When x = i, we proceed as follows.
Note: i =
i² =(√-1)(√-1) = -1
i³ = (√-1)(√-1)(√-1) = -1(√-1) = -1i = -i
f(x) = x³ – 2x²
f(i) = i³ – 2i²
= -i – 2(-1)
= -i + 2
= 2 – i
Step-by-step explanation:
The slope of line passing through the given point (-3,-1),(2,8) is
Step-by-step explanation:
We need to find slope of line passing through the given point (-3,-1),(2,8)
The formula used to find slope is:
We are given points (-3,-1) and (2,8)
Putting values and finding slope:
So, the slope of line passing through the given point (-3,-1),(2,8) is

Question:
The graph represents the two companies' prices. What is the linear equation that represents each T-shirt company?
Answer:
1.) Shirt Box: y = 7.5x + 30
2.) Just Tees: y = 10.5x
Step-by-step explanation:
For Number -<u>One</u>- We do - 7.5 + 30 = 37.5
For Number -<u>Two</u>- We do - 10.5 <u>×</u> "X"
You See We have to solve for "X"
This is just to give the idea, and Kinda help Explain it. . .
