Solve log812 = x – 2 . round your answer to four decimal places.

Step-by-step explanation:

Given:

The equation to solve is given as:

In order to solve this, we use the base change formula of logarithms.

The base change formula is given as:

Therefore, the equation can be rewritten as:

Adding 2 on both the sides, we get:

Now, we know that,

Plug in these values and solve for 'x'. This gives,

Therefore, the value of 'x' is 3.1950 rounded to four decimal places.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
