Answer:
9.09090909091% decrease
Step-by-step explanation:
1 - 10/11 = 1/11 = 9.09090909091%
X + 2y = -8
-x - y = -4
y = -12
x = -8 - 2 (-12) = -8 + 24 = 16
It has a one solution
7.0, 7.2, 7.4, 7.6, 7.8, 8.0
Hello!
We have
x+4/2x-1<0
x+4<2x-1
x>5 Hope this helps you out. Any questions please just ask. Thanks so much!
Answer:
CR = 17 ; PR = 30
Step-by-step explanation:
From the problem hypothesis we know that CD⊥PR or CQ⊥PR(perpendicular) and ∡PCQ ≡∡RCQ (bisector)
so ∡PCQ≡∡RCQ
[CQ]≡[CQ] (common side)
CQ⊥PR
--------------------------------------------
⇒(cathetus - angle case of congruence)⇒ ΔPQC≡ΔRQC so [PQ]≡[QR] (=15) // PR = PQ+QR ⇒ PR=30
from this congruence ⇒ΔPRC = isosceles so PC=CR=17
Hint: in any triangle is bisector of an angle it is perpendicular on the opposite side then triangle is isosceles.
