If
varies directly as
, then there is some constant
for which

Similarly, there is some constant
such that

Given that
when
, we have

Now when
, we get

So u times it first so -15p-15-63+9p
so it would short it down because of cobine like terms -6p-78
X=27
You have to divide 4x=108 and you get 27!
15% off means 85% on so I would use .85x · 6 = total monthly cost to represent this problem. The dot represents times (I did not want to confuse things by using x)
Other ways to express this:
6 x .85x
6(.85x)
.85x (6)
Answer:
It is given that , In ΔW X Y, Y X is perpendicular to W Z. Also, y w= w z.
To Prove: ΔW X Y ≅ ΔZ Y X
Proof:
In Δ W X Y and Z Y X
Y X ⊥ W Z→→→→Given
Y W= Y Z→→(Given)
∠YWX=∠YZX→→As, opposite sides of a triangle are equal, so angle opposite to them are equal.
∠YXW=∠YXZ→→Each being 90°
So, ΔYXW≅ΔYXZ→→[AAS]
Also, YX is common sides between two triangles.
ΔYXW≅ΔYXZ→→[HL]
So,the two triangles can be proved congruent by either AAS, or HL.
