Well, to began I suggest factoring out the expression on your own, correctly, to find the mistake they made.
I use to series of blanks to do this as follows:
6x^2-3x-9
3(2x^2-x-3)
i)
__ * __ =-3
(2)__ + __= -1
ii)
1 * -3= -3
(2)1 + -3 = -1
3(2x-3)(x+1)=0
From this form we can derive the x values as 3/2, and -1 if we needed to do so
Explanation:
Although these expressions are equivilant, Jamal's function is more coherent. He expresses that x+1=0 which can be solved as x=-1 rather than having to do 3x+3=0 => 3x=-3 => x=-1. Jamal's factor gives the function within a single step.
This form is the simplest form possible as Jamal noticed that the trinomial was divisible by 3 initially. Jennifer on the other hand did not factor out the 3 initially in the equation. As a result, here function less coherently states the properties of the function.
Hope this helps.
Answer:
The "what" is 100
Step-by-step explanation:
Rewrite this as 37.6y = 3760 and set out to determine y:
y = 3760/37.6 = 100

![[3, 4]](https://tex.z-dn.net/?f=%5B3%2C%204%5D)
Step-by-step explanation:
{5x + 2y = 23
{13x + 3y = 51
−5⁄13[13x + 3y = 51]
{5x + 2y = 23
{−5x - 1 2⁄13y = 19 8⁄13 >> New Equation
______________________
11⁄13y = 3 5⁄13
_____ ______
11⁄13 11⁄13
[Plug this back into both equations above to get the x-coordinate of 3]; 
I am joyous to assist you anytime.
