You first subtract 1/2 and 1, which gets you -0.5.
then you are left with -0.5=8x
you divide 8 on both sides. which will now give you: x = -.0625
and -0.0625 is your answer :)
Here it is given that AB || CD
< EIA = <GJB
Now
∠EIA ≅ ∠IKC and ∠GJB is ≅ ∠ JLD (Corresponding angles)
∠EIA ≅ ∠GJB then ∠IKC ≅ ∠ JLD (Substitution Property of Congruency)
∠IKL + ∠IKC 180° and ∠DLH + ∠JLD =180° (Linear Pair Theorem)
So
m∠IKL + m∠IKC = 180° ....(1)
But ∠IKC ≅ ∠JLD
m∠IKC = m∠JLD (SUBTRACTION PROPERTY OF CONGRUENCY)
So we have
m∠IKL + m∠JLD = 180°
∠IKL and ∠JLD are supplementary angles.
But ∠DLH and ∠JLD are supplementary angles.
∠IKL ≅ ∠DLH (CONGRUENT SUPPLEMENTS THEOREM)
Answer:
Therefore the value is

Step-by-step explanation:
Given:
....Given
Step 1. Applying Distributive Property A(B+C)=AB+AC we get


Step 2. Add 15 both the side

Step 3. Dividing both the side by 9

Therefore the value is

Domain of 3ˣ = ( -∞, ∞ )
<em>Note : Domain of an exponential function is always ( -∞, ∞ )</em>
