Answer:

-3

Step-by-step explanation:

First, you look at which way it is going. From left to right, the line is going down, so the slope is negative. Change in y is 3 and change in x is 1. From any two points on the line, the y value changes by 3 every time the x value changes by 1.

Answer:

-3

Step-by-step explanation:

slope = rise/run

rise = vertical distance

run = horizontal distance

Step 1. Find two easy to read points on the line. Use points on intersections of grid lines.

For example, choose points (0, -3) and (-1, 0).

Step 2. Start at one point, say (0, -3). We must go to the other point using only vertical and horizontal moves. Go up 3 units. That is a rise of +3. It's positive 3 since up is positive. Now go left 1 unit. That is a run of -1. It is negative because going left is negative.

Step 3.

slope = rise/run

slope = 3/(-1) = -3

Answer: slope = -3

I want to buy a car for $17,500 and I make 13 an hour roughly how long would it take me to reach my goal? & how many hours w

Aneli [31]

Answer:

1347 hours

Step-by-step explanation:

Assuming the income is net income (total after taxes etc.):

Cost of car = $17,500
Net income = $13 per hour

To calculate the number of hours to be worked to save enough to buy the car, divide the cost of the car by hourly net income:

$\begin{aligned}\implies \textsf{Number of hours to work} & = \dfrac{\textsf{Cost of car}}{\textsf{hourly net income}}\\\\& = \sf \dfrac{17500}{13}\\\\& = \sf 1346.1538...\end{aligned}$

We have to round the number up to 1347 hours, as only $17,498 will be saved if 1346 hours are worked.

The average working week is approximately 40 hours, therefore to calculate how many weeks it would take to earn enough money to purchase the car, divide the number of hours by 40:

⇒ 1347 ÷ 40 = 33.675

So it would take 34 weeks, working an average of 40 hours a week and not spending any of the money earned, to save enough to purchase the car.

Yanka [14]

Answer: 144 minutes

Step-by-step explanation:

Based on the information that has been given in the question, the minutes that the slower pipe alone can use in filling the tank can be denoted by y minutes.

Therefore, the faster pipe will fill it in 1/3 × x = x/3 minutes.

Therefore,

1/x + 3/x = 1/36

4/x = 1/36

x = 36 × 4

x = 144

The number of minutes taken by the slower pipe will be 144 minutes.
