1- Find the trigonometric values
Hope this helps :)
Although you have not included the statements about the solution to the set of the given equations, I can explain you what happen with that system.
You can arrive to the same conclusion by any method of solution of systems that you like.
The quickest in this case, is to multiply the equation of the lIne F by 5.
That leads to: 5 (x + y) = 5(8)
⇒ 5x + 5y = 40.
Now you can realize that the two representations (equations) correspond to the same line.
That means that there are infinite solutions, this is infinity values of x and y meet both equations.
If you graph line E and line F they overlap in the entire domain, so the graphing method also tells you that you cannot find one solution but infinite soluttions.
it's called the distance formula. The square root of (-5-7)^2+(-1-(-6))^2
This simplifies to the square root of -12^2+5^2, or the square root of 144+25.
144+25=169.
the square root of 169 is 13
Answer:
the
Step-by-step explanation:
1 ,17,87,901,674
<u>Answer:</u>
No solution
<u>Step-by-step solution:</u>
We are given an expression:
We have only one variable 
so we will make the subject and solve for it.
Solving the brackets first to get:
Taking LCM on both sides to get:
By cross multiplication:
gets cancelled so we are left with 
Therefore, has no solution.
