Answer:
First option is correct.
Step-by-step explanation:
Let amounts of money James may have after he sees Rita be x.
It is given that either James borrowed $12 from his friend Rita or she borrowed $12 from him.
So meeting Rita second time either he will $12 or he will receive $12.
The amounts of money James may have after second meeting with Rita is:
Case 1: If he pays $12.
.... (1)
Case 1: If he receives $12.
.... (2)
On combining equation (1) and (2), we get

Subtract 42.80 from both sides.

It can be written as

Therefore first option is correct.

Step-by-step explanation:
We must determine the x and y intercepts of the parabola:
When y=0, x=0 or x=10
WE know that the point of the triangle base is x and x+8. We can substitute this into the parabola equation because the endpoints are on the parabola.
f(x+8)
f(x+8)
f(x)=f(x+8)

solve for x


Therefore the heigh is f(1):

The area of the triangle is 1/2 base x height:
