For this case as MNOP is a square then the angles of each vertex are equal to 90 degrees.
Therefore, we have the following equations:
![4t + 20 = 90\\7f + 6 = 90](https://tex.z-dn.net/?f=%204t%20%2B%2020%20%3D%2090%5C%5C7f%20%2B%206%20%3D%2090%20%20)
From these equations, we can clear the values of the unknowns.
For equation 1 we have:
![4t + 20 = 90\\4t = 90 - 20\\4t = 70](https://tex.z-dn.net/?f=%204t%20%2B%2020%20%3D%2090%5C%5C4t%20%3D%2090%20-%2020%5C%5C4t%20%3D%2070%20%20)
![t = \frac{70}{4}\\t = 17.5](https://tex.z-dn.net/?f=%20t%20%3D%20%5Cfrac%7B70%7D%7B4%7D%5C%5Ct%20%3D%2017.5%20%20%20)
For equation 2 we have:
![7f + 6 = 90\\7f = 90 - 6\\7f = 84](https://tex.z-dn.net/?f=%207f%20%2B%206%20%3D%2090%5C%5C7f%20%3D%2090%20-%206%5C%5C7f%20%3D%2084%20%20)
![f = \frac{84}{7}\\f = 12](https://tex.z-dn.net/?f=%20f%20%3D%20%5Cfrac%7B84%7D%7B7%7D%5C%5Cf%20%3D%2012%20%20%20)
Answer:
The values of t and f are given by:
![t = 17.5\\f = 12](https://tex.z-dn.net/?f=%20t%20%3D%2017.5%5C%5Cf%20%3D%2012%20)
Answer:
the coordinates will be (0,9) (-8,0) and the equation will be y=(9/8x)+9
Step-by-step explanation:
Im not 100% sure but if im right please mark me as brainliest
You can just add the terms:
<span>(-x^2+9)+(-3x^2-11x+4) = -4x</span>² - 11x + 13
I don’t know i need points sorry so sorry
