Answer:
B.
Step-by-step explanation:
In mathematics, a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a symbol, called the imaginary unit, that satisfies the equation i² = −1. Because no real number satisfies this equation, i was called an imaginary number by René Descartes.
Answer:
C
Step-by-step explanation:
The number of points either side of the line of best fit are equal (3 points either side) and the line is the line of best fit.
We have to translate the coordinates using the given rule.
The given rule is (x-4,y+3)
Now we have to translate the point A(4,6) using the given rule.
Then,
A' is (4-4,6+3)=(0,9)
Now the point B(-2,3) is to be transformed.
Then,
B' is (-2-4,3+3)=(-6,6)
Hence the answer is A'(0,9) and B'(-6,6)
A. She can multiply the bottom equation by -4 and then add the equations to solve for h.
-4g - 15h = -17
4g - 20h = -52
Add them to get
-15h = -17
-20h = -52
From here, you can solve for h.
Assume that pi is approx. 3.14. Then 86.92 = approx. 27 2/3 times pi, or
86.92 is approx. equal to 83pi/3.
