coupon
#6: john has a coupon for 20% off any item in a store. what would the final cost be for an item that originally cost $15 if he uses his coupon? (assume there are no taxes)

5. See below

6. $12

Step-by-step explanation:

5.

Image/Graph attached.

The maximum amount of gas in the gas tank was 60 ounces:

The max amount is at the starting, at t = 0. The y-axis (amount of gas) at that time is at 30, so the max amount is 30, NOT 60.

False.

The amount of gas in the gas tank is at a maximum at 0 minutes:

This is true, because the more you drive, the less gas you have. You have a full tank/max before you start. That's at t = 0 minutes.

True.

The gas tank will be empty after 60 minutes:

The y-axis goes to 0 at t = 60 minutes. That means, after 60 minutes, gas is over. Tank is empty. So this is true.

True.

6.

If something costs $15 and John uses a coupon on that, he will get 20% off of that. The final price would be 20% (0.2) less than the original, $15. We need to find 20% of 15 and then subtract from 15.

20% of 15 = 0.2 * 15 = $3

Now

15 - 3 = $12

#5 False, True, True

#6 $12

Step-by-step explanation:

#5 In the figure attached, the missing picture is shown.

#6 The discount is equal to 20/100 * $15 = $3. Then, John has to pay $15 - $3 = $12

answer: c i think

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
