Ellipses, parabolas, and infinity. A parabola can be defined as the locus of points equidistant from a fixed point (called the focus) and a fixed line (called the directrix). But we know from projective geometry that parabolas and ellipses are essentially the same object.
Answer:
1170
Step-by-step explanation:
195000 * 0.006= 1170
Answer:
x=1 and y=-2
Step-by-step explanation:
5-2i-7=-2-2i
x-(3-yi)=x-3+yi
we write this equation -2 - 2i = (x-3) +yi
so -2=x-3 and -2i=yi
+3 +3 :i :i
1=x -2= y
so x=1 and y= -2
Answer:
x = -2
Step-by-step explanation:
5x + 7 = 2x + 1
subtract both sides by 2x
3x + 7 = 1
subtract both side by 7
3x = -6
divide both sides by 3
x = -2
The answer is D, dilation by a scale factor of 2 followed by reflection about the y- axis.
