So for this, I will be doing the elimination method. Firstly, multiply both sides of the first equation by 2:
Next, add the two equations together to get 
. From here you can solve for x.
For this equation, just divide both sides by 8 and your first answer will be 
Now that we have the value of x, substitute it into either equation to solve for y:
<u>In short, the solution is (2,-5), or A.</u>
Answer:8.5
Step-by-step explanation:
Pythagorean Theorem
A
a^2 + b^2 = c^2
3^2 + 8^2 = c^2
9 + 64 = c^2
73 = c^2
C= Sqrt (73)
C = 8.5
Answer:
The correct answer is option C and D.
C). DC = 6√3
D). AC = 12√3
Step-by-step explanation:
Answer:
