Chia is planning a sailing party for her friends the boat rental is $150 plus an additional $15 per person see it has saved up $

storchak [24]

150 + 15x = 400
(-150) 150 + 15x = 400 (-150)
15x = 250
(/15) 15x = 250 (/15)
x = 16.67
So Chia can invite 16 people

Solve the following inequality.

Anika [276]

Solving the inequality given algebraically, the solution of the inequality for the value of m is:

m < -4 OR m > 3

Given the following inequality,

$\frac{m - 2}{3} < -2 \\$

4m + 3 > 15

Let's solve algebraically for the value of m in both inequality statements given.

$\frac{m - 2}{3} < -2 \\$

Multiply both sides by 3

$\frac{m - 2}{3} \times 3 < -2 \times 3\\\\m - 2 < -6$

Add 2 to both sides

$m - 2 + 2 < -6 + 2\\\\m < -4$

4m + 3 > 15

Subtract 3 from each side

4m + 3 - 3 > 15 - 3

4m > 12

Divide both sides by 4

$\frac{4m}{4} > \frac{12}{4} \\\\$

m > 3

Therefore, solving the inequality given algebraically, the solution of the inequality for the value of m is:

m < -4 OR m > 3

Solve the decay equation y' = -ky using the integrating factors method. Show work

Alex777 [14]

Answer:

$y=\frac{c}{e^{kx}}$

Step-by-step explanation:

$\frac{\mathrm{d} y}{\mathrm{d} x} =-ky$

$\frac{\mathrm{d} y}{\mathrm{d} x} +ky=0$

comparing with equation

$\frac{\mathrm{d} y}{\mathrm{d} x} + Py=Q(x)$

$I.F.= e^{\int P dx}$

$I.F.= e^{\int k dx}$

$I.F.= e^{kx}$

$y=\frac{1}{I.F.} ( \int {Q(x)} dx +c)$

$y=\frac{1}{e^{kx}} ( \int {0} dx +c)$

$y=\frac{c}{e^{kx}}$
