Answer:
A, y + 3 = 2(x + 2)
Step-by-step explanation:
Point slope form is y -y1 = m(x - x1)
To find the equation for this line, plug in y1, m, and x into the equation.
m = 2
y1 = -3
x1 = -2
y - -3 = 2(x - -2)
Since subtracting a negative changes the sign to a positive, the equation becomes:
y + 3 = 2(x + 2)
This is option A.
Answer:
(6,1)
Step-by-step explanation:
Just look for the terms with x and y in them. Divide their coefficients by two, and multiply by -1. And then put them in an ordered pair.
So in this case, -12x --> 6 and -2y --> 1
Obviously the more orthodox way would be to actually complete the square, but I'm lazy, this way is faster, and since this seems to be multiple choice, as long as you have the correct answer, it shouldn't matter.

Answer:
45 hours
Step-by-step explanation:
1 mile * <u>1609 meters </u> * <u> 1 s </u> = 160900 sec
1 mile .01 meters
160900 sec / 60 /60 = 44.7 = 45 hours
