A. x = –4
uysha [10]
Please, please, post only ONE question at a time.  The way Brainly is set up, it's very difficult to conclude one problem and then move on to the next in the same session.

<span>Solve y = log3243.  I must make the assumption here that you mean:

</span><span>Solve y = (log to the base 3) of 243.
</span>
Solve y = (log   243   in better, more compact form.
                      3

If you recognize that 243 is an integer power of 3, the problem becomes much easier.  
                  2             3            4                  5
Note that 3   = 9,    3   = 27, 3   =81, and 3   = 243.

Also note that the log function and the exponential function are inverses of one another, and that inverse functions "undo" each other.
                      x
Thus, log    3     is simply x.
               3
                                           5
Thus, log    243  =  log     3    = 5 (answer).
                3                   3

Please repost the rest of your questions, one at a time, and then I will gladly help you with them.

yaroslaw [1]

Answer:

385.50 pesos

Step-by-step explanation:

total amount earned = daily rate + amount paid for overtime

In 6 days, he would earn = 450.50 x 6 = 2703

Total amount earned for overtime = 5,594.25 - 2703 = 2891.25

rate per hour during overtime = 2891.25 / 7.5 = 385.5 pesos

Does anyone know how to do this? HELP ASAP PLEASE!
Mumz [18]

Answer:

MT = 50 units

Step-by-step explanation:

The sides opposite to the congruent angles are equal.

3x - 10 = 2x + 10

3x - 2x = 10 + 10

x = 20

MT = 3x - 10

= 3(20)-10

= 50 units

When point J (-14,6) is rotated 180 degrees around the origin, what is the resulting point J'? a (14,-6) b (-14,6) c (14,6) d (-
elena55 [62]

Answer:

J' = (14,-6)

Step-by-step explanation:

Given

J = (-14,6)

R_0 = 180^\circ

Required

Determine J'

When a point (x,y) is rotated 180 degrees around the origin, the new point is (-x, -y).

So:

J = (-14,6)

J' = (14,-6)
