Find the slope the line that contains the points (1,9) and (-5,8). what is the slope formula?

Tresset [83]

Answer: 1/6

Step-by-step explanation:

Lets say two points are (a,b) and (c,d)

the slope that cross these two points is: (b-d)/(a-c) or (d-b)/(c-a) → either one is fine, but make sure the one you are subtracting is the one from the same point.

Hope it helped!

you and your friend start biking to opposite directions from the same point. You travel 108 feet every 8 seconds. Your friend tr

juin [17]

Answer:

To find your distance apart, you can convert 15 minutes to seconds because that is what the rate is given in.

15 mins x 60 seconds = 900 seconds.

Step-by-step explanation:

In 900 seconds, there are 900/8=112.5 groups of 8 seconds. This means there are 112.5 groups of 108 feet.

112.5 x 108 = 12150 feet

12150 feet/5280 feet is approximately 2.3 miles.

For your friend you take 900/6 = 150 groups of 6 seconds.

150 x 63 = 9540 feet

9540 feet/5280 feet = 1.79 miles

1.79 miles + 2.3 miles = 2.09 miles

You and your friend are about 2.09 miles apart after 15 minutes.

B). If you go 2.3 miles every 15 minutes, that means you travel about 0.77 miles every 5 minutes. If you travel 20 more minutes (40-15-5) that would be 0.77x 4=3.07 miles more

3.07 + 2.3 = 5.37 miles after 40 minutes (you).

Your friend travels 1.79 in 15 minutes, so 1.79/3 = 0.6 miles every 5 minutes

0.6 x 5 (5 x 5 = 25 minutes)= 3 miles

1.79 + 3 miles= 4.79 miles (friend)

4.79 + 5.37 = 10.16 miles

You and your friend are about 10.16 miles apart after 40 minutes.

Nathaniel purchases a one year membership pass to an art museum as a member he receives a discounted entrance fee the total cost

Arturiano [62]

For this case, we must find the equation of the line.
The generic equation of the line is:
$y-yo = m (x-xo)
$
The slope of the line is:
$m = \frac{y2-y1}{x2-x1}$
Substituting values we have:
$m = \frac{15-12}{2-0}$
Rewriting:
$m = \frac{3}{2}$
$m = 1.5$
We now choose an ordered pair:
(xo, yo) = (0, 12)
Substituting values we have:
$y-12 = 1.5 (x-0)$
Rewriting the equation:
$y= 1.5x+12$
For 20 visits, we evaluate the equation when x = 20.
We have then:
$y= 1.5(20)+12$
$y= 30+12$
$y= 42$
Answer:
The discounted entrance fee is 1.5$. The total cost is 42$ after 20 visits
