Adjecent basically means "next to" and perpindicular is meeting at an right angle (90 degrees) so squares have them and right angle triangles do to.
Answer:
Please write out in english
Step-by-step explanation:
I cannot help unless you can translate.
Step 1 you need to cross multiply
Then divide both sides by eight which will then give you this answer
K= 3/2
We are given the equations 3x+5y=-3 and x-5y=-5.
Both equations have a 5y term which allows us to easily solve the system by elimination. To do so we will add the equations together like a simple addition problem by adding the x terms together, the y terms together, and the integer answers together.
3x + 5y = -3
+x - 5y = -5
---------------
4x + 0y = -8
The y terms cancel out since one is positive and one is negative. Now we can solve for x.
4x = -8

x = -2
Now plug -2 in for x in one of the original equations to find y.
(-2) - 5y = -5
-5y = -3
y = 3/5
Our answer as an ordered pair is (2, 3/5)
