Find the quotient. 9.9) 80.19

Graph the lines by finding the points of intersection with the axes (intercepts):

Ostrovityanka [42]

To solve this problem you must apply the proccedure shown below:

1. You have the following function:

$y=-\frac{1}{2} (x-1)$

2. You can rewrite it as following:

$y=\frac{(-x+1)}{2}$

3. The line intersects the y-axis when $x=0$ , therefore:

$y=\frac{(0+1)}{2}=\frac{1}{2} =0.5$

4. The line intersects the x-axis when $y=0$ :

$0=\frac{(-x+1)}{2}\\ 0=-x+1\\ x=1$

5. Now plot the points (0, 0.5) and (1,0) in a graph , as you can see in the figure attached.

Therefore, the answer is: The points of intersection are (0, 0.5) and (1,0).

Michael went to dinner with his friend. Their total was $25.70. If they left a 20% tip, what was their total

lana66690 [7]

Answer: $20.56

Step-by-step explanation:

Let's take our given total and use this equation

25.70(n)

n will equal 0.80 in this case, as they left a 20% tip so we need to find out what 80% of 25.70 is first

$25.70(0.80)$

$20.56 is the total without the tip!

Are these lines parallel,

Darina [25.2K]

Answer - Perpendicular

First, find the slope of each line by using the point slope formula [(y2-y1)/(x2-x1)]. You should get that the slope line 1 is -2/3 and the slope of line 2 is 3/2. Using this, we can conclude that both the lines are perpendicular because their slopes are opposite reciprocals (meaning you flip one fraction and change its sign to get the other fraction).

Today joelle walked at a rate of 3 miles per hour and she ran 15 minutes at a rate of 6 miles per hour.How many total miles did

svetoff [14.1K]

I added a screenshot with the complete question

Answer:
Total miles = 2.5 miles

Explanation:
1- While walking:
We are given that Joelle walked 20 minutes at a rate of 3 miles per hour.
This means that she walked $\frac{20}{60} = \frac{1}{3}$ of an hour at a rate of 3 miles per hour
The formula that relates distance, time and velocity is:
Distance = velocity * time
Substitute with the givens to get the distance she covered while walking:
Distance = 3 * $\frac{1}{3}$ = 1 mile

2- While running:
We are given that Joelle ran 15 minutes at a rate of 6 miles per hour
This means that she ran $\frac{15}{60} = \frac{1}{4}$ of an hour at a rate of 6 miles per hour
The formula that relates distance, time and velocity is:
Distance = velocity * time
Substitute with the givens to get the distance she covered while running:
Distance = 6 * $\frac{1}{4}$ = 1.5 miles

3- getting the total mileage:
Total distance she covered = distance while walking + distance while running
Total distance she covered = 1 + 1.5
Total distance she covered = 2.5 miles

Hope this helps :)
