So, the man is 6 feet, but casts a 9 foot shadow. So, you divide 25 by 9, and then you would find it goes into it 2.8 times, so round and get 3 if you want,or keep it. And then 12, or round to 13.
1) Sketching it
Since the line segment AD = 10x -5 and AC= 3x +1 and CD= 15
According to the Segment Addition postulate we can write:
3x+1+15=10x-5 <em>Combining like terms</em>
3x +16 = 10x -5 <em>Subtract 16 from both sides</em>
3x = 10x-5-16 Subtract 10x from both sides
3x-10x =-21
-7x = -21
7x=21 <em>Dividing by 7 on both sides</em>
x=3
The correct answer would look something like this:
Answer:
y=x+2
Step-by-step explanation:
Given, m = 1
Eqn of st line is y = mx + c
y = 1*x + c
y= x + c ........eqn (i)
since, the line passes through the point (4,2)
4 = 2 + c
c = 4 - 2
c = 2
Now, Putting the value of c = 2 in eqn (i)
y = x + 2 is req eqn of line
