Answer:
25 miles
Step-by-step explanation:
4 days is 10 miles, 8 days is 20 miles. In order to find two days, divide the days and miles in half, leaving you with 2 days and 5 miles left. Therefore, 10 days is 25 miles. I hope this helped!
3x+14/2x+1=12/3 cross multiply
9x + 42 = 24x + 12
15x = 30
x = 2
ps: we are literally doing this in geometry
9 1/2 cups 2 quarts equal 8 cups so add 8 to 1 1/2 and you will get 9 1/2
Perpendicular
If you plotted both on a graph, it would be two straight lines that make 90° angles
Answer:
k = -10/7 and k = -3
Step-by-step explanation:
Given: <em>y</em> = <em>kx</em> + 2
where k is the slope of line and 2 is y-intercept.
∵ line <em>y</em> = <em>kx </em>+ 2 is passing through point <em>P</em> (-7, 12), ∴ <em>x</em> = -7 and <em>y </em>= 12
Now substituting the value of x and y in above equation,
<em>y </em>= <em>kx</em> + 2
12 =<em> k</em>(-7) + 2
-7<em>k</em> = 12 - 2
- 7<em>k</em> = 10
![k = \frac{-10}{7}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B-10%7D%7B7%7D)
In the same way, ∵ line <em>y</em> = <em>kx </em>+ 2 is passing through point <em>P</em> (3, -7), ∴ <em>x</em> = 3 and <em>y </em>= -7
<em>y </em>= <em>kx</em> + 2
Now substituting the value of x and y in above equation,
-7 =<em> k</em>(3) + 2
<em>3k</em> = -7 - 2
<em>3k</em> = - 9
<em>k</em> = -3
