Answer:
D
Step-by-step explanation:
A does not work, because you stop on the way to the meeting (which you don't)
B does not work, because you speed up on the way to the meeting, when in reality you slow down
C does not work, because it does not show that you went back home or changed speed at all
D is correct!
Answer:
Step-by-step explanation:
We want a line parallel to 3x − 4y = 7. Any such line will have an equation of the same form but a different constant.
If the new line is to pass through the point (-4, -2), replace x with -4 and y with -2. We obtain:
3(-4) − 4(-2) = -12 + 8 = -4. Thus, the desired new equation is 3x − 4y = -4.
This could also be written as 3x − 4y + 4 = 0. We could also solve this for y, obtaining:
3x + 4 = 4y, or y = (3/4)x + 1.

Yes they are equivalent. This is because if you simplify each fraction : 288/12 and 240/10 they both equal 24.
After manipulating above equation we get, 2x^2 - 7x - 8= 0. Discriminant= b^2 - 4ac = (-7)^2 - 4(2)(-8) = 113>0. So there are 2 real roots :)
