1st one: only mentions 1 p wrong
2nd one: saving means (-) cost so this is also wrong
3rd one: how much you owe is x-y and there is no (-) sign in there so it is wrong

the answer is the 4th one because it has p+14%p if p=price and 14%p=14% of p tax

a water tank is draining at a constant rate if after five minutes the tank is drained by 4.5 gallons what is the rate in gallons

vova2212 [387]

Answer:

The rate is 0.9 gallon per minute

Step-by-step explanation:

Here, we have 4.5 gallons drained in 5 minutes but we are interested in calculating the rate per minute

Let the amount drained per minute be x

4.5 gallons = 5 minutes

x gallon = 1 minute

Let’s cross multiply;

x * 5 = 4.5 * 1

5x = 4.5

x = 4.5/5

x = 0.9 gallons

3x=x+40
Subtract x from both sides
2x=40
Divide both sides by 2nto get x by itself
x=2
Plug 2 in for x
m∠4 = (3x)
m∠4 = 3(2)
Solve
m∠4 = 6

Find the domain of the graphed function.

Darya [45]

The domain of the graphed function is [-3, 2)

<h3>How to determine the domain and the range?</h3>

From the given graph, we have the following highlights:

Minimum x value = -3 (closed circle)
Maximum x value = 2 (open circle)

Open circles are represented with () while closed circles are represented with []

Hence, the domain of the graphed function is [-3, 2)
