Answer: first answer choice
Step-by-step explanation:
They give us that f(0) and g(0) = 4 and f(2) = g(2) = 0, so the answer is simply the first one. When x=0, y=4 for both and when x=2, y=0 for both.

For the first one, 2/5 is the constant rate of proportionality because you are using it in a y=kx equation.
Next time, please begin with a question of your own, and share whatever work you have done.
Look at the illustration. You want to reflect point J in the origin. Point J's coordinates are (0,3). If you reflect this point in the origin, you'll get the new point J' as (0,-3).
Next, reflect point I in the origin. The original point I is (-4,4). Reflecting this in the origin takes you from Quadrant 2 to Quadrant 4. The coordinates of the new point I' are (4,-4). Spend enuf time with this so that it becomes clear.
Next, reflect point K in the origin. You might want to draw a straight line thru point K and the origin. The new point, K', will lie on this line the same distance from the origin as is the old point K is from the origin.
If there are 500 mg of medicine in 5 ml of liquid, we need to set up a proportion to find out how much liquid medication has 125 mg of medicine in it. Set up the proportion as follows:
.
Cross multiply to get 500x = 625. Divide by 500 to get that you need 1.25 ml of liquid if your dose is 125 mg of medicine.
