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
y = -2 and x= 3
Graph is attached below. Black line is the graph of y=-2
Blue line is the graph of x=3
Whenever we get equation like x = something, in that case slope is always undefined
Whenever we get equation like y = something, in that case slope is always 0
y = -2 and x= 3
For x=3, the slope is undefined.
The graph of x=3 is a vertical line at 3 on x. The x intercept is 3 and there is no y intercept.
For y=-2, the slope is 0
The graph of y=-2 is a horizontal line at -2 on y. The y intercept is -2 and there is no x intercept.

Answer:
42 boys can count (given)
P(boy & can count) = 0.35
Step-by-step explanation:
P(boy who can count) = 42/120
