The last choice, f(x)=1/4(4ˣ⁻⁻¹)-4, is correct.
Substituting our values for x, we have:
f(2) = 1/4(4²⁻¹)-4 = 1/4(4¹) - 4 = 1/4(4) - 4= 1 - 4 = -3
f(3) = 1/4(4³⁻¹)-4 = 1/4(4²) - 4 = 1/4(16) - 4 = 4 - 4 = 0
f(4) = 1/4(4⁴⁻¹)-4 = 1/4(4³) - 4 = 1/4(64) - 4 = 16 - 4 = 12
All of the data points fit.
To work out percentage, divide what they've done (21) by the total distance (50), then multiply it by 100 to get the percentage
(21/50)*100 = 42%
Answer:
Oliver walked 3 miles in 2 hours and he walked 24 miles in 16 hours.
Step-by-step explanation:
Divide 9 by 6 and you'll get 1.5. 1.5 goes into 3 two times, so the first answer is 2 and then do 16 times 1.5 and you'll get 24.
Hope this helps.
