Answer:
500
Step-by-step explanation:
Given: P = 150 - T where P is passenger cars and T is trucks
10P = 7T ⇔ P = 
Plug in equation 2 into equation 1:
= 150 - T
Solving for T, we get 500

Answer:
A vertical angle!
Step-by-step explanation:
Vertical angles sit across from each other.
<em>Note: Your question seems a little bit ambiguous. So, I am assuming the given function f(x)=9x+7.</em>
<em>Thus, I am solving based on it. It would still clear your concept. </em>
Answer:
The inverse of f(x)=9x+7
Step-by-step explanation:
Given the function

A function g is the inverse of function f if for y=f(x), x=g(y)
Replace x with y

solve for y


Therefore,
The inverse of f(x)=9x+7 is:
i.e.
