Answer:
2 hours
Step-by-step explanation:
9.6/(60/5 x 0.4) = 2 hours
/ = divide
x = multiply
Answer: -3
Step-by-step explanation: 15 - 18 = -3
The derivative of the function is 2x+6.
At the particular point (2,6), plug in the x coordinate for x.
2(2)+6 = 10
Hope this helps :)
Solve each equation for y and then the slope is m and y-intercept is b as in:

So, if you do that, you'll get (remember, this is <em>after</em> solving for y):
1. m = -6, b = -2
2. m = 5, b = -1
3. m = -5/3, b = 5
4. m = 0, b = -1/4
5. m = -1, b = -3
6. m = 3, b = -4
7. m = 1/2, b = -5/2
8. m = 7/2, b = 1
Hope this helps.
Basically solve for y
minus 5x fromboth sides
-15y=-5x-60
divide both sides by -15
y=1/3x+4
