Answer:
$67.90
Step-by-step explanation:
First lets calculate the subtotal, or the price before the coupon is added:
2(12)+1(28)+1(45)=97
Subtotal: $97.00
Okay Now lets apply the coupon, to do this we'll multiply the subtotal by 0.7 since the coupon removes 30% from the price and 1 - 0.3 = 0.7
97 * 0.7 = 67.9
Total: $67.90
Answer Choice D
7/8 gallons in 1/2 hour
Looking for gallons per hour, or
.
So, this is basically a division problem of 7/8 divided by 1/2. Dividing by a fraction is the same as multiplying by that fraction's reciprocal.
Now we simplify by a factor of 2:
And here we are! There are 7/4 gallons leaking per hour. This is the same as 1.75 gallons per hour. Hope this helps! :)

Answer: -2</h3>
========================================================
Explanation:
Plug in x = -1 to find that
f(x) = 2|x-1|
f(-1) = 2|-1-1|
f(-1) = 2|-2|
f(-1) = 2*(2)
f(-1) = 4
If you repeat for x = 1, you should find that f(1) = 0

Now use the average rate of change formula below. Effectively, we're using the slope formula more or less.
The average rate of change on this interval is -2
This is the same as finding the slope through the points (-1, 4) and (1, 0).
Y = 2.5x + 10 (Increasing)
y= -0.5x + 0.5 (Decreasing)
y = -4.5x + 3 (Decreasing)
y = -0.5x − 5 (Decreasing)
y = -2x + 7 (Decreasing)
y = -5x − 12 (Decreasing)
1)y = -5x − 12
2)y = -0.5x − 5
3)y= -0.5x + 0.5
4)y = -4.5x + 3
5)y = -2x + 7
6)y = 2.5x + 10 (increasing)
Decreasing/increasing = slope mx
y int = b (from mx + b)
