Use log rule
log(ab) = log a + log b

Take log of both sides:
ln 4 + ln 4^x = ln 10 + ln e^{-x}

Use log rule
log(a^n) = n*log(a)

ln 4 + xln 4 = ln 10 -xln e \\  \\ ln 4 + xln 4 = ln 10 -x \\  \\ x ln 4+x = ln 10 - ln 4 \\  \\ x(ln 4 +1) = ln 10 -ln 4 \\  \\ x = \frac{ln 10 - ln 4}{ln 4 +1}

X-1/3 = y-2/4
4(x-1) = 3(y-2)
4x-4 = 3y-6
4x-3y = -2 --->1
4x +3y =8 ---->2
2-1 ; 6y = 10
y = 10/6 or 5/3
And 4x + 3(10/6) = 8
4x =3
X = 3/4

Nina works at an hourly rate of $12.25 per hour and worked 46 hours last week. She earns overtime for hours exceeding 40 hours.
Alenkinab [10]

Answer:

$600.25

Step-by-step explanation:

12.25 per week

46hrs last week

40+ = overtime

Overtime = t*1.5

------------------------------

46-40= 6hrs of overtime

40*12.25= 490 - this is her money for working 40hrs.

To figure out the money amount of overtime pay--- 12.25*1.5= 18.375 (18.38)

<em>18.38*6= 110.25</em>

add now

<em>110.25+490= $600.25</em>


=) ~i hope i helped~ =)
