Answer:
False
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m = -
, hence
y = -
x + c ← is the partial equation
to find c substitute (- 3, 5) into the partial equation
5 =
+ c ⇒ c = ![\frac{17}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B4%7D)
y = -
x +
← equation of line
Answer: B
Explanation:
First box do 6•4•5=120
Second box do 4•4•4=64
Then 64+120=184
Then 184-200=16
Is this your exact question? Can you explain a bit more what the question is asking?
Let's say the distance is "x".
time = distance / rate
time1 = x / 40
time2 = x/80
A) time1 shoud be twice time2 or (time1 / time2) =2
B) time1 -1 = time2
Substituting equation B) into A)
((time1 / (time1 -1) = 2
time1 = 2* time1 -2
time1 = 2 hours time2 = 1 hour
Distance = 80 miles
1st trip time1 = 80/40 = 2 hours
return trip time2 = 80/80 = 1 hour
total trip = 160 miles in 3 hours
average speed = 53.333333 miles per hour
Answer:
85 Adult tickets, 109 Children tickets
Step-by-step explanation:
2,377.40 divided by $13.90 = 171.0359712 = 171 (rounded)
2,377.40 divided by $10.85 = 219.1152074 = 219 (rounded)
171 divided by 2 = 85
219 divided by 2 = 109
85 A
109 B
