Answer: g(x) is shifted 4 units left and 6 units down from f(x)
Step-by-step explanation:
<span>x+yi = <span>8/(<span>4+8i)</span></span></span><span>x+yi = <span>2/(<span>1+2i)</span></span></span><span>x+yi = <span>2/(<span>1+2i) </span></span>× (<span><span>1−2i)/(</span><span>1−2i)</span></span></span><span>x+yi = (<span><span>2−4i) /</span>5</span></span><span><span>x+yi = <span>2/5</span>−<span>4/5</span>i

Answer:
D. 102.6 in²
Step-by-step explanation:
The area of the square is 9 in² (3 × 3 = 9)
The area of the rectangle is 30 in² (3 × 10 = 30)
The area of the circle is 63.585 (a = πr², a = 3.14 × 4.5² - remember that the radius of a circle is half of the diameter)
Now, we can add these numbers together. 9 + 30 + 63.585 is 102.585 in² which is 102.6 in² rounded to 1 decimal place.
Hope this helps!
Answer:
3rd. row becomes [0 0 -6 1]
Step-by-step explanation:
The element of pivot is the 9 in the 2nd row, so the 1st and 2nd rows stays the same.
For the 3rd row we have to calculate in each column, the element of the 3rd row minus the element of the 2nd row, and put it in the 3rd row.
This way we have <em>four operations</em> as follow:
for columns 1 to 4 in that order.
With this procedure, the system becomes
[1 –2 3 1]
[0 9 2 –5]
[0 0 –6 1]
