Slope of a function is defined as the rate of change of a function. It determine the unit price of values or amount traveled in unit time.
<h3>Slope of a function</h3>
Slope of a function is defined as the rate of change of a function. It determine the unit price of values or amount traveled in unit time.
The formula for expressing the slope of a function is given as;
f'(x) = f(b)-f(a)/b-a
a and b are the intervals
The slope can also be expressed as a function of its coordinate (x, y)
Slope = y2-y1/x2-x1

I guess you want to find the average speed for the whole journey
average speed = distance travelled / time
the distance from home to the shop = speed * time = 0.5*10 = 5 miles
time for travelling back = distance / speed = 5/30 = 1/6 hours
average speed for whole journey = 10 / (1/2 + 1/6) = 10 * 3 / 2 = 15 mph
Answer: -7
Step-by-step explanation:
w = -1, x = -2, y = -3, z = -4
z/x + -8y + 2w - wxyz
(-4)/(-2) + (-8)(-2) + (2)(-1) - (-1)(-2)(-3)(-4)
2+ 16 + (-1) - (24)
