15.5% is the same as 15.5/100 or 155/1000, which you can take a 5 out of.
After that, you will get 31/200
Let y represent the total weight of mulch and x represent the number of bags of mulch, then
y = kx.
Rate of change (k) = y/x. i.e. the weight of mulch divided by the number of bags.
Answer:
2f (x) is stretched in the y direction by a factor of 2, and f (x) is shrunk in the y direction by a factor of 2 (or stretched by a factor of ).
Step-by-step explanation:
f(x) is the standard function, 2f(x) makes the parabola "skinnier" by stretching the Y axis.
The answer to that is 2.5,-6.5
