first convert 400.000 m to km, 400 km
80 km /h x 5h= 400km
so it going to take 5 hours of travel
Use slope intercept form to write the equation y=mx+b m (slope of the line) will be the hourly fee, and b (y-intercept) will be the one-time transportation fee.
y=30x+20
to find the cost of renting a canoe for 6 hours, plug 6 into the equation replacing x
y=(30×6)+20
y=180+20=$200
Sorry, I can't graph the line, but I would number the x-axis of the coordinate plane (graph) by 1s or 2s (for the hours), and the y-axis by 20s (for the cost)
Answer:
-2
Step-by-step explanation:
the answer is -2, as shown
Either use a graphing calculator or substitute the value of x for x
That would be -1, -4. since it is in quadrant 3. :)
