Answer:
( -1 , 26)
Step-by-step explanation:
So since you need to find the other endpoint, you would follow these steps:
1.) ![4 = \frac{9 + x}{2\\}](https://tex.z-dn.net/?f=4%20%3D%20%5Cfrac%7B9%20%2B%20x%7D%7B2%5C%5C%7D)
2.) 8 = 9 + x ( you just multiplied the 2 to the 4 to get 8)
3.) -1 = x (just solve it like a regular equation, so just subtract 9 on both sides to get rid of it and that leaves you with -1 = x)
You took the x values of both points and put them in the equation.
And its the same for y
1.) ![8 = \frac{-10 + y}{2}](https://tex.z-dn.net/?f=8%20%3D%20%5Cfrac%7B-10%20%2B%20y%7D%7B2%7D)
2.) 16 = -10 + y
3.) 26 = y (you added the 10 on both sides because the 10 was negative and that took the 10 out and so it left you with 26 = y)
Answer:
10
Step-by-step explanation:
4x2.5=10CM2
the area of a rectangular =width multiply its length
For the solution I isolated the variable by dividing each side by factors that don't contain the variable.
x = -6 + ∛2 / 2
x ≈ -5.37003947
Hope this helps!! :3
