8. The y-intercept is -10. You can find this by just seeing where the line would hit the y-axis. This is basically the starting point so the Scuba Diver's decent started at -10m.
9. You have the y-intercept so put that in slope-intercept form. y=mx+b
y=mx - 10
Now find the slope by picking two points and using the slope formula. I'll use
(30,-6) and (50,-4), and then plug in the values. 30 = x1, -6 = x2, 50 = x2, -4 = -4. Simplify.
m= y2-y1 -4 - (-6) 2 1
-------- = ----------- = --- / 2 = ---
x2-x1 50 - 30 20 10
A) -180m
b) 510-180=+330m
+330/45=7.333m/s
c) total distance = 840m
average speed = 840/105
= 8m/s
Answer:
T=306
Step-by-step explanation:
Simplify both sides of the equation and separate the variable
(or just times 51 by 6)
Statement A is correct.
7.99m is the unit rate for how much you will pay for each pound of meat.
5.99c is the unit rate for how much you will pay for each pound of cheese.
Answer:
6/1
Unit rate = 6
Unit rates are ratios that compare two measurements (units) and the second measurement is 1 (per)
