Answer:
f(2) =1
Step-by-step explanation:
f(2) is the y value of the graph when x =2
When x=2, y=1
so f(2) =1
3x-2y=7
3x=7
x=7/3
-2y=7
y=-7/2
so...(7/3,-7/2)

29 1.2. Constructing Direct Proofs 1. Let a, b, and c be real numbers with a 0. The solutions of the quadratic equation ax 2 + bx + c = 0 are given by the quadratic formula, which states that the solutions are xi and x2. where and x2 2a 2a (a) Prove that the sum of the two solutions of the quadratic equation ax2 + bx + c = 0 is equal to -b/a . (b) Prove that the product of the two solutions of the quadratic equation ax2 + bx + c = 0 is equal to c/a.
The proving of both a) and b) has been done

Step-by-step explanation:
<u>Answer:</u>
It will take 2 hours 36 minutes for the two trains to meet.
<u>Step-by-step explanation:</u>
The distance between the two trains is decreasing by 
miles per hour, which can be written as 
.
So at this rate, the distance between the trains will be reduced to zero in:
Changing 2.6 hours to hours and minutes:
Therefore, it will take 2 hours 36 minutes for the two trains to meet.
