Answer: 1.5 meters.
Step-by-step explanation:
Given: At the beginning of spring, the ice starts to melt.
The variable s models the ice sheets thickness in meters t weeks after the beginning of spring.
At t=0, s=4 meters
At t=1, s=3.75 meters
∴It is a linear equation, where the rate of change in thickness = 3.75-4=0.25 meter per minute .
The decrease in ice sheet in every 6 weeks =

Answer:
X= 7
Step-by-step explanation:
Since x= 2 you would plug it in 3.5 times 2 = 7
well i cannot help u graph but u need to get them in y=mx+b form first
2x+y=4
y=-2x+4
2y-4x=6
2y=4x+6
y=2x+3
now that the problems are in y=mx+b form, u can graph them. the "b" is your y-intercept. you need to graph this first so what ever ur be is, put a point there on the y axis. then use your slope to plant your line. slope is rise/run. so for the top problem start at your y intercept and go down 2 and to the right 1. and for the bottem problem, start at your y intercept then go up 2 and to the right 1
HOPE THIS HELPED!
