Answer:
Step-by-step explanation:
The x-intercept of Line B is already given to you because it is where the graph intersects the x-axis.
Now, to get the x-intercept of Line A, plug 0 in for <em>y</em><em> </em>to get this:
0 = −2x + 4
- 4 - 4
_____________
So, the x-intercept of Line A is and since 2 is greater than −6, <em>greater than</em> would be your answer.

<u>Given</u>
Solving (a): Solve for time
We have:
Cross multiply
Make t the subject
Solving (b): Solve for distance
We have:
Cross multiply
You can get all the terms on one side, and then solve for x by any means:
Factor out a -2:
Factor this equation:
I will use the AC method. To use it, first multiply a and c (in ax^2 + bx +c):
Now, look for two numbers that multiply to -12 and add to -11. Obviously these numbers are -12 and 1. (-12*1 = -12 and -12+1 = -11). Now, because of rules, you set it up in a Punnett square:
4x^2 -12x
x -3
Now, we find common factors of the terms in rows:
_x_______-3__
4x| 4x^2 -12x
1 | x -3
So, you can use this to write an equivalent expression to the quadratic given:
Now, we known the factors are (solve for x): 3 and -1/4.
