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
0,-3 is the answer. This is the answer because it says what is the solution
Answer:
im not sure
Step-by-step explanation:
assume all of them were neon
![15 \times 3 = 45](https://tex.z-dn.net/?f=%2015%20%5Ctimes%203%20%3D%2045)
difference between all neon and actual price
![52 - 45 = 7](https://tex.z-dn.net/?f=52%20-%2045%20%3D%207)
difference between neon and metallic
![4- 3 = 1](https://tex.z-dn.net/?f=4-%203%20%3D%201)
number of metallic sets
![7 \div 1 = 7](https://tex.z-dn.net/?f=7%20%20%5Cdiv%201%20%3D%207)
number of neon sets
![15 - 7 = 8](https://tex.z-dn.net/?f=15%20-%207%20%3D%208)
Answer:
5x
Step-by-step explanation:
5x means 5 times somethin
so i think it would be 5x
