Answer:
C. the average total cost for the first month of a gym membership
Step-by-step explanation:
x=1 is for month 1,
the value of y includes 1-month fee and one off payment, so this is the average total for the first month of membership
Step-by-step explanation:
the second and the 6th options keep the same graph but shift it to the left.
the other options :
the first option changes the graph (the factor -2 stretched and flips the graph).
the third and the 5th options shift the graph up and down. but not to the left.
the 4th option shifts it to the right.
when you add a constant inside the x terms, you shift to the left.
when you subtract a constant inside the x terms, you shift to the right.
e.g. when having f(x+2), then everything, that should happen at x+2 happens already at x. 2 units earlier, and therefore a shift to the left.
in the other direction, f(x-2) makes everything that should have happened at x-2 happen finally at x. so, everything shifts 2 units to the right.
To easily solve for the ratios, divide the weight by the mass.
196/20 = 9.8
9.8 is your multiplier.
Divide 1078 by 9.8
1078/980 = 110
X = 110
Your question is the ratio of weight to mass, so from right to left.
Your correct answer is B.)
