Answer:
The x-coordinate of the solution to this system of equations is <u>1</u>.
Step-by-step explanation:
Given,

We have to find out the x-coordinate of the equation.
Solution,
Let 
Again let 
Now using elimination method we will solve the equations.
For this we will add equation 1 and equation 2 and get;

Now on dividing both side by '9' we get;

Hence The x-coordinate of the solution to this system of equations is <u>1</u>.
Answer:
(x+3) is a factor of your question
Step-by-step explanation:
x²-6x-27
x²+3x-9x-27
x(x+3)-9(x+3)
(x+3)(x-9)
Answer:
(a^2)+4a-5
Step-by-step explanation:
(3+a+2)(a+2-3)
(a+5)(a-1)
use FOIL or box method
5a-5+(a^2)-a simplifyes to
(a^2)+4a-5
Answer:
We use tree diagram by connecting relevant samples
Step-by-step explanation:
thats all
Answer: The interest is $453.60.
The total amount includes principal + interest. The principal was 630 and the total amount was 1083.60.
1083.60 - 630 = 453.60.
