Answer:
x=-2+3t , y=-9-10t
Step-by-step explanation:
I'm going to start by solving the first equation for t....which will give (x-x1)/(x2-x1) =t.
You can now substitute this in the second equation to get....y=y1 + (y2-y1)(x-x1)/(x2-x1)
Rearranging, you get y-y1 = (y2-y1) / (x2-x1) * (x-x1) which is equivalent to y-y1= m(x-x1) which is the point-slope formula for a line.
So since t was varying between 0 and 1,
plugging in t=0 you get x=x1 and y = y1 givin you the coordinate (x1,y1)
similarly, plugging in t=1 leads to (x2,y2)
So this is a representation of a segment connecting these 2 points.
B) just plug in the points into your given formula from part a to get...
x=-2 +(1--2)t and y = 9 +(-1-9)t
or x=-2+3t , y=-9-10t
Answer:
Perpendicular bisector
Step-by-step explanation:
Have a great day!!
Ok, so area/width=length
then they gave you mixed fractions
they want you to practice converting mixed fractions into improper fractions and dividing them
rmember, improper fractions are a/b where a>b sometimes
and also remember that
okie dokie
width
4 and 1/2=width
4+1/2=width
8/2+1/2=width
9/2=width
area=36 and 3/4
area=36+3/4
area=144/4+3/4
area=147/4
so area/width=length
so the length is
You need a function that maps a number to its cube.
y = x^3
Answer:
Step-by-step explanation:
Total amount of water = 500 ml
Mary drank = 400 ml
<u>Left:</u>
= 500 ml - 400 ml
= 100 ml
This was divided equally among 4 friends.
So,
<u>Each friend got:</u>
= 100 ml/4
= 25 ml
