Answer:
Equation of the line is y = -x + 4
Step-by-step explanation:
When the two lines having their slopes 
and 
are perpendicular to each other then 
If is the slope of the line passing through two points (0, 3) and (4, 7) then
= 
= 1
Now slope of the second line perpendicular to first line will be
= 
= -1
Slope intercept form of the equation of a line is represented by
y = mx + c
where m = slope
c = y intercept
Since the line is passing through (-1, 3) and slope = -1, therefore,
3 = -1 + c
c = 4
Now we plug in these values in the equation.
y = -x + 4
Equation of the line is y = -x + 4
Step-by-step explanation:
For 2 people it uses 1 1/3 cups
1 1/3 = 1.33
So for 4 people Tomas will use
1 1/3 + 1 1/3 = 2.66 or 2 2/3 cups
First, Rico walked for 3/10 of a mile which is 30/100 of a mile.
Hen, Rico walked for 24/100 of a mile.
Then you add 24/100 and 30/100. 24+30/100 which is 54/100.
Answer=54/100 of a mile
Answer:
AD= 15
AB=30
Step-by-step explanation:
We are given that the Point D bisect the line segment AB
Hence AD = DB
AD= 4x-1
BD=9x-21
Hence
4x-1=9x-21
adding 21 on both sides and subtracting 4x from both sides
4x-4x-1+21=9x-4x-21+21
-1+21=5x
5x=20
dividing both sides by x we get
x=4
Hence
AD = 4x-1
= 4(4)-1= 16-1=15
AD= 15
AB = 2 x AD
= 2 x 15
= 30
