Answer:Find the distance between the parallel lines m and n whose equations are y = x + 4 and y = x - 6, respectively.
There are several ways to do this...here's one
Let (0, 4) be a point on the first line
Then.......a line with a negative reciprocal slope going through this point will have the equation :
y = -x + 4........so......we can find the intersection of this line with y = x - 6....set both equations equal
-x + 4 = x - 6 add x, 6 to both sides
10 = 2x divide both sides by 2
5 = x
So...using -x + 4, the y value at intersection = -1.......
So...we just need to find the distance from (0,4) to ( 5, -1) =
√[ (5)^2 + (4 + 1)^2 ] = 5√2 ≈ 7.07 units
Here's a pic....AB is the distance with A = (0,4) and B = (5, -1)
Step-by-step explanation:
The answer is 3x2 + 8x + 8. (the 2 infront of 3x means squared I just could type it)
Answer:
2
Step-by-step explanation:
32-8x=7x+2
32=15x+2
30=15x
x=2
6 because 10 is bigger than the 6 or use it like this 6<10 or 10>6 it might be the right answer
Answer:
28.5
Step-by-step explanation:
Take the total # of pages to be READ, 128.5, divide by the # of days, 4.5, your answer is pages to read per day. 128.5/4.5 =28.55. Check your answer by multiplying 28.55x4.5 = 128.5
Hope this helps.
