Answer:
6) x = 17 ft
7) 42 in
Step-by-step explanation:
6) length of the tangents are equal.
2x - 7 = 27
2x = 34
x = 17
7) if you draw a line from T passing through the centre of the circle, it will divide the triangle into two congruent triangles
Perimeter = 2(5+7+9) = 42 in
Given:
Fixed salary = $1400
Additional salary = $500 each time he sells a car.
To find:
The equation for the situation and how much money he will make if he sells 7 cars.
Solution:
Let y be the total salary of the salesman after selling x cars.
He will earn an extra $500 each time he sells a car. So, extra money earned by him after selling x cars is 500x.
Total salary = Fixed salary + Additional salary
![y=1400+500x](https://tex.z-dn.net/?f=y%3D1400%2B500x)
Substituting
, we get
![y=1400+500(7)](https://tex.z-dn.net/?f=y%3D1400%2B500%287%29)
![y=1400+3500](https://tex.z-dn.net/?f=y%3D1400%2B3500)
![y=4900](https://tex.z-dn.net/?f=y%3D4900)
Therefore, the required equation for the given situation is
and the salesman will earn $4900 if he sells 7 cars.
