<span><span>5e^x + 12 = 27
5e^x = 27 - 12
5e^2 = 15
Take natutal log of both sides.

ln(5e^x) = ln15

x(ln5e) = ln15
Divide both sides by ln5e to get an approximate answer, which is always the case with logs.
NOTE: lne = 1 and so, ln5e becomes 5 times 1 or 5.
x ≈ ln15/5
x ≈ 0.54161004
Round your answer to two decimal places.
Then we get x ≈ 0.54

Complete the point-slope equation of the line through -6 comma 5 and -3 comma -3

Anna007 [38]

Step-by-step explanation:

<h3>Given points </h3>

A (-6,5)
B (-3,-3)

${\boxed{\sf Slope_{(m)}=\dfrac{y _2-y_1}{x_2-x_1}}}$

Substitute the values

$\qquad {:}\longrightarrow\mathbb m=\dfrac {-3-5}{-3+6}$

$\qquad {:}\longrightarrow\mathbb m=\dfrac {-8}{3}$

$\therefore\sf Slope=\dfrac {-8}{3}$

vlada-n [284]

Answer:

The medium-sized can is the cheaper by the oz, and is $0.005 per oz. cheaper.

Step-by-step explanation:

Medium can: $0.92/(46 oz) = $0.020/oz

Large can: $3.60 / (144 oz) = $0.025/oz

Surprisingly, the medium can price per oz. is lower than that of the large can. The difference is $0.005 per oz.
