The answer is (d) where x = -1 & 9
Answer:
y=15x+250 (x is the number of guests)
Step-by-step explanation:
the 15 is the slope, so that is the number that has to be multiplied by. The 250 is an additional fee that doesn't change, so it's just added on.
F = ma
the question said, F and M both are doubled ,so,
2F =2ma
but you can see the result is same !!
so acceleration doesn't change !! so final acceleration is also 2.2 !!
