Answer
Cameron forgot to do the same thing to the 9. Instead of dividing 3 by 3 and 9 by 3 he only divided 3 by 3.
Step-by-step explanation:
3/7 × 4/9
You can divide the 3 and 9 by 3 so you get 1/7 × 4/3.
Then you do 4 × 1 and 7 × 3.
Correct answer is 4/21
Answer:
x=-8
Step-by-step explanation:
y=8 is a horizontal line crossing the y-axis at 8
A line perpendicular to this would be a vertical line crossing the x-axis at -8
Hello from MrBillDoesMath!
Answer:
2 - i
Discussion:
Evaluate F(x) = x^3 - 2 x^2 when x = i.
i^2 = -1 for i^3 = i ( i^2) = i (-1) = -i
So F(i) = (i)^3 - 2 (i)^2
= -i - 2(-1)
= -i + 2
= 2 - i
which is the last answer shown
Thank you,
