y = -1/25x + 30
The +30 represents the 30 gallons of gasoline at the beginning of Samantha's road trip.
As each mile, x, does by, 1/25 of a gallon is lost (because the van gets 25 miles per gallon). so you put a negative 1/25 in front of the x. Therefore, when Samantha has driven x miles, she will have y gallons of gas left.
Answer:
<u>The correct answer is B. -6, -5 2/5, - 4 1/5</u>
Step-by-step explanation:
Let's find the 1st, 4th and 10th terms of this arithmetic sequence, as follows:
A(n)= -6 + (n-1) *(1/5)
A(₁)= -6 + (1 - 1) * (1/5) = -6 + (0) * (1/5) = -6
A(₄)= -6 + (4 - 1) * (1/5) = -6 + (3) * (1/5) = -6 +3/5 = -5 2/5
A(₁₀)= -6 + (10 - 1) * (1/5) = -6 + (9) * (1/5) = -6 + 9/5 = -4 1/5
<u>The correct answer is B. -6, -5 2/5, - 4 1/5</u>
Answer:
Step-by-step explanation:
distance = rate * time(d = rt)....and we are looking for time(t)...so let me rearrange this equation......t = d / r
t = d / r
distance (d) = 38 miles
rate (r) = 2 miles per hr
t =38/2 = 19 hrs
ur answer is C. 38/2
