Solve for x by using log. Rounded to hundredth. <br><br> <img src="https://tex.z-dn.net/?f=4%5E%7B2x-5%7D%20%3D6%5E%7B-x%2B1%7D"
wel

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

How do I do 86+y=99 the picture that is attached to this is how the teacher wants us to do it but I don’t understand help please
Anni [7]

Okay, take for example:

1+2=3 is the same as 1=3-2

See how we changed the place of the 2. We can do that as long we change + to - and vica versa.

Let's see your example:

6+y=-8

We move the 6 on the other side of the expression with the opposite sign (it is a rule) and we get:

y=-8-6

y=-14

The answer to your question is

86+y=99

y=99-86

y=13

Use a compass to measure the length of AB.

Draw an arc from point B (or point A) with that distance.

Extend line AB through that arc and label the intersection as point C.

AC is twice the length of AB.
