First expand the equation.
-5e+5+6e = -17
Next, combine the like terms.
e+5 = -17
e = -22
I think that number one is C. I'll try and solve the second one as well.
(-5,6) is the vertex.
I did this by using the vertex x coordinate Formula which is -b/2a
So in this case a=3 b=30 c=81
So if put the number in it would be
-30/2(3) = -30/6 = -5
Now that we know the x coordinate of the vertex which is -5. You plug the x of -5 into the quadratic equation to get the y.
3(-5)^2 + 30(-5) + 81=y
Simplify it
75-150+81= Y
Combine the light terms
6=y
So the coordinate points are (-5,6)

i have no idea kiddo
Currently we 8 in the thousands' place, followed by 615. Since 615 is greater than 500, round up that 8615 to 9000, which is to the nearest thousand.
