Answer:
Step-by-step explanation:
203 miles in 3.5 hrs....and 243 miles in 4.5 hrs
totaling : (203 + 243) miles in (3.5 + 4.5) hrs = 446 miles in 8 hrs
speed = distance / time
speed = 446 / 8
speed = 55.75 mph <==
Answer:
x = 17.5
Step-by-step explanation:
5/8 = x/28
=> 5(28) = 8x
=> 140 = 8x
=> 8x = 140
=> x = 140/8
=> x = 70/4
=> x = 35/2
=> x = 17.5
Answer:
f(x+1) = -3/4 × f(x)
Step-by-step explanation:
first of all, the sign of the numbers in the sequence is alternating. so, there must be a "-" involved.
that eliminates the first and third answer options.
and the absolute values of the numbers in the sequence are going down. |f(x+1)| < |f(x)|
that eliminates the fourth answer option, as this says that
|f(x)| < |f(x+1)|. and that is the opposite of how the actual sequence behaves.
