Solve 3^(2x) = 7^(x-1) −7.74293 7.74293 −1 1

Hello,

3^(2x)=7^(x-1)
==>2x ln 3 = (x-1)ln 7
==>x(2ln 3 -ln 7)=-ln 7
==>x=-ln 7 /(2 ln 3-ln 7)
==>x=-7,7429304889740634853601918674823...

Answer A

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

when multiplying or dividing by a negative on both sides you have to flip the inequality sign. this rule only applies to multiplying or dividing by a negative number in inequality equations. this rule is really important.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
