The scientific notations is 2.9x10^9
Answer:
B
Step-by-step explanation:

use the point (-5,3)
y-3=-(x-(-5)) = y-3= -(x+5)
I believe the answers can be narrowed down to A or D, it depends on which direction its moving in and at which location you desire to measure each.
A quadratic equation is an equation whose leading coefficient is of the second degree. The factored form of the quadratic equation x²-x-2 is (x+1)(x-2).
