Answer:
F. y = .25x + 3
Step-by-step explanation:
use the slope equation m = y2-y1/x2-x1 with the points. so for this problem it would look like: m = 6-2/12-(-4) which is 1/4 (.25).
For the y-intercept plug what you already know (slope and a set of points) into the slope-intercept formula: 2 = .25(-4) + b and solve.
2 = -1 +b
+1 ( add the one)
b = 3 and that's the y-intercept

Karen sent 25. Carlos sent 51. Also sent 17. The method is here if you want it. :)
Answer:
Its 8
Step-by-step explanation:
3x+10+2x=50
3x+2x=5x
5x+10=50
5x+10-10=50-10
5x=40
x=8
5x8=40
<u>Answer- </u>Wendy spent 3 hours on the train
<u>Solution-</u>
The distance between the cities= 500 mi.
She traveled part of the way by bus, and other part by train.
The bus averaged 40 mph, and the train averaged 120 mph.
The entire trip took 6.5 hours.
let d = distance traveled by train
the total distance was given as 500 mi ,
therefore, distance traveled by bus = (500-d) mi
time = distance/speed
⇒ train traveling time + bus traveling time = 6.5 hrs
⇒
⇒ d + 3(500-d) = 120(6.5)
⇒ d + 1500 - 3d = 780
⇒ 2d = 720
⇒ d = 360 mi
so d = 360 mi by train
⇒ 360/120 = 3 hrs on the train
