Answer:
Step-by-step explanation:
To find the slope of the equation use 
.
So, 
= 
. Now we can use our slope and any of the two points to write in point-slope form, which is 
. Using the point (7,-6), the formula will give .
To check, you can plug in this equation and the points into a calculator to graph. The line passes through both points.
Answer:
LM = 33 units
Explanation:
From the drawing:
LM = NP
41 - 2x = 7x + 5
41 - 5 = 7x + 2x
36 = 9x
x = 9
This means that:
LM = 41 - 2x
LM = 41 - 2(4)
LM = 33 units
Hope this helps :)
To get the answer we can use proportion.
30----------100%
12-----------x
Cross multiply now
30x=12*100%
30x=1200% /:30 (divide both sides by 30)
x=40% - it's the percentage of cars which finished the race.
100%-40%=60% - it's the answer
Answer:
100cm
Step-by-step explanation:
the tenths of cm are 10,20,30 etc.
X / 6/7 is 3 2/5. First, concert the numbers to decimals for simplicity sake, and you get x/.857 = 3.4. Multiply both sides by .857 to get x alone and you get x ≈ 2.9143
