Answer:
Equation of the line that passes through the point (-2,7) and has a slope of zero is given as
![y=7](https://tex.z-dn.net/?f=y%3D7)
Step-by-step explanation:
Equation of line is given as
-----------(1)
Here
![m=0 \ \ \ and \ \ \ (x_1, y_1) = (-2, 7)](https://tex.z-dn.net/?f=m%3D0%20%5C%20%5C%20%5C%20and%20%5C%20%5C%20%5C%20%28x_1%2C%20y_1%29%20%3D%20%28-2%2C%207%29)
Substituting values in equation (1)
![y-7=0(x+2)\\y=7](https://tex.z-dn.net/?f=y-7%3D0%28x%2B2%29%5C%5Cy%3D7)
Answer:
x = 14
Step-by-step explanation:
![f(x) = 10 - \frac{9}{2} x \\ \\ plug \: f(x) = - 53 \\ \\ - 53 = 10 - \frac{9}{2} x \\ \\ \frac{9}{2} x = 10 + 53 \\ \\ \frac{9}{2} x = 63 \\ \\ x = 63 \times \frac{2}{9} \\ \\ x = 7 \times 2 \\ \\ x = 14](https://tex.z-dn.net/?f=f%28x%29%20%3D%2010%20-%20%20%5Cfrac%7B9%7D%7B2%7D%20x%20%5C%5C%20%20%5C%5C%20plug%20%5C%3A%20f%28x%29%20%3D%20%20-%2053%20%5C%5C%20%20%5C%5C%20%20-%2053%20%3D%2010%20-%20%20%5Cfrac%7B9%7D%7B2%7D%20x%20%5C%5C%20%20%5C%5C%20%5Cfrac%7B9%7D%7B2%7D%20x%20%20%3D%2010%20%2B%2053%20%5C%5C%20%20%5C%5C%20%5Cfrac%7B9%7D%7B2%7D%20x%20%20%3D%2063%20%5C%5C%20%20%5C%5C%20x%20%3D%2063%20%5Ctimes%20%20%5Cfrac%7B2%7D%7B9%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%207%20%5Ctimes%202%20%5C%5C%20%20%5C%5C%20x%20%3D%2014)
