Factorise fully:<br>8p2 – 12pc<br>(2)​
Vilka [71]

Answer:

so im unsure if the (2) is in the equation so i have two answers

(with 2) 8p      (−3c+p)

(without 2) 4p(−3c+2p)

Step-by-step explanation:

(with 2)

Factor 8p2−12pc(2)

−24cp+8p2

=8p(−3c+p)

answer 1: =8p(−3c+p)

(without 2)

Factor 8p2−12pc

−12cp+8p2

=4p(−3c+2p)

answer 2: =4p(−3c+2p)

Somebody help me with these worksheets pls<br><br><br> (Please answer properly)
xenn [34]

This is an interesting problem.

But first, let us define what are the three possible cases :

A system of linear equations : a system of equation is when you have two equations with the same unknown variables, that you need to solve both together. Example : "x+y = - 7 AND x + y = - 4" are two equations that form a system of equation.

Plus they are linear, a linear equation is simply an equation of the form : y = ax + b where a and b are real numbers.

Here for example x + y = - 7 is a linear equation. Because y = 1 × x - 7

where a = 1 and b = - 7.

Consistent Dependent : A system of equation is consistent Dependant when it has an infinite number of solutions.

<h2><u><em>When this is the case, the graphs of the lines in the system are the same, meaning the equations in the system represent the same line. </em></u></h2><h2 />

Consistent Independent : A system of equation is consistent Dependant when it has exactly one solution.

<h2><em><u>When this is the case, the graphs of the lines in the system cross at exactly one point. </u></em></h2><h2 />

Inconsistent : A system of equation is Inconsistent if it haas no solutions.

<h2><em><u>When this is the case, the graphs of the lines in the system do not intersect, meaning they are parallel. </u></em></h2><h2 />

Now, with those definitions above, we can work on our problem :

1. x + y = - 7 and x + y = - 4

Look at the picture attached the lines are parallel to each other so here the answer is Inconsistent

2. Same line : consistent dependent

3. Parallel Lines : Inconsistent

4. Lines cross at exactly one point :Consistent Independent

5. Lines cross at exactly one point : Consistent Independent.

You can see the graph of each systems in the pictures attached below.

Good luck, you will succeed :)
