Answer: $x=1.91$

Step-by-step explanation:

Given the expression $4^{2x-5} =6^{-x+1}$ , apply logarithm to both sides. Then:

$log(4)^{2x-5} =log(6)^{-x+1}$

Remembert that according the the properties of logarithms:

$log(a)^n=nlog(a)$

Then:

$(2x-5)log(4)=(-x+1)log(6)$

Appy distributive property and solve for "x":

$2xlog(4)-5log(4)=-xlog(6)+log(6)\\2xlog(4)+xlog(6)=log(6)+5log(4)\\x(2log(4)+log(6))=log(6)+5log(4)\\\\x=\frac{log(6)+5log(4)}{2log(4)+log(6)}\\\\x=1.91$

Match the justifications for each step in order to prove the Alternate Interior Angles Theorem. Note that lines p and q are para

Alex_Xolod [135]

Answer:

Option (3)

Step-by-step explanation:

There are two parallel lines 'p' and 'q' and a transversal line is intersecting these lines at two distinct points.

Each pair of angles formed on the inner side of the parallel lines but opposite sides of the transversal line are the alternate interior angles.

Pair of angles (∠2 and ∠6) and (∠3 and ∠7) are the alternate interior angles.

Since, alternate interior angles are equal in measure,

∠2 ≅ ∠6

∠3 ≅ ∠7

Option (3) will be the answer.

A = 8: b = ; C = 10.

lara [203]

Answer:

b=6

$a^{2} + b^{2} = c^{2} \\ {8}^{2} + {b}^{2} = {10}^{2} \\ 64 + {b}^{2} = 100 \\ 100 - 64 = {b}^{2} \\ 36 = {b}^{2} \\ \sqrt{36} = \sqrt{ {b}^{2} } \\ 6 = b$
