Step-by-step explanation:

6< 3x + 9

-3x < 9-6

-3x < 3 .( -1 )

3x > 3

x > 3/3

x > 3

3x + 9 ≤ 18

3x ≤ 18-9

3x ≤ 9

x ≤ 9/3

x ≤ 3

S = {XeIR/ 3 > x ≤ 3 }

A cup of coffee at 181 degrees is poured into a mug and left in a room at 66 degrees. After 6 minutes, the coffee is 139 degrees

katen-ka-za [31]

Answer:

Step-by-step explanation:

$\frac{dT}{dt} =k(t-66)\\T=\int\ {k(t-66)} \, dt=K(\frac{t^2}{2} -66)+c\\when t=0,T=181\\181=K(0-66)+c\\181=-66k+c\\when t=6,T=139\\139=k(\frac{6^2}{2} -66)+c\\139=-48k+c\\181-139=-66k+48k\\-42=-18k\\7=3k\\k=\frac{7}{3} \\139=-48*\frac{7}{3} +c\\c=139+112=251\\T=\frac{7}{3} (t-66)+251\\now complete the question$

Solve this equation for x. Round your answer to<br>the nearest hundredth.<br>7 = In(x + 5)<br>

oksian1 [2.3K]

Answer:

x ≈ 1091.63

Step-by-step explanation:

Using the rule of logarithms

$log_{b}$ x = n ⇔ x = $b^{n}$

note that ln x is to the base e

Given

ln(x + 5) = 7, then

x + 5 = $e^{7}$ ( subtract 5 from both sides )

x = $e^{7}$ - 5 ≈ 1091.63 ( nearest hundredth )
