Point (-2,-6) isn't a solution of this system of equations.
Point (-4,3) is a solution of this system of equations.
Answer:
The value of x is 12
Step-by-step explanation:
To find the value of x, we need to note that the interior angles are equal to 180. We also know that angle R is equal to 180 - (8 + 6x). So we can add all of this together and set equal to 180.
180 - (8 + 6x) + 4x + 2 + 30 = 180
180 - 8 - 6x + 4x + 2 + 30 = 180
-2x + 24 = 0
-2x = -24
x = 12
Answer:
(x-8)(x+3)
Step-by-step explanation:
1) Find out what are the factors of the constant?
2) Which of those add to equal the coefficient before the x value?
In this particular equation, we have the constant being 24. The first two factors that come to mind are 6 and 4, and 8 and 3. Since it is -24, we need one of these numbers to be negative.
Let's look at our "b" value, or the coefficient behind the x value, 5. Looking at our factors and thinking of addition (since one of them must be negative, it will most likely be subtraction instead of addition) I can see that
8+ −3=5
which is one of the factors of -24.
This means that we can factor our equation using these numbers, getting us the following:
(x−3)(x+8)
