4.7 x 10 : 3.1 x 10
= 47 : 31
This is true.
It comes from the same side interior angles theorem which says that same side interior angles are supplementary, only if the lines are parallel.

Answer:
B. hyperbola, 45°
Step-by-step explanation:
This is rotation in quadratic equations
Perform elimination of xy term
Ax² +B xy+Cy²+Dx+Ey+F=0
Rotation of axes of the coordinates through angle θ to satisfy
Cot 2θ =(A-C)/B
But B≠ 0 and A=C=0
Answer will be hyperbola, 45°
8.28 dived by 18 = 0.46
so 0.46X12=5.25
and there is your answer Hope this helped XD
