Ratling [72]

Let

x--------> the number of sessions

y-------> the total payment

we know that

without membership:

$y=6x$ --------> equation $1$

with membership:

$y=100+4x$ --------> equation $2$

using a graph tool------> resolve the system of equations

see the attached figure

the solution is the point $(50,300)$

that means

For $x=50\ sessions$

the cost is $\$300$ in both forms

to justify buying the membership

$x > 50\ sessions$

therefore

the answer is

$x > 50\ sessions$

Solve Ax+Hy=K for x Help!

denis23 [38]

Answer:

$x = -\frac{Hy + K}{A}$

Step-by-step explanation:

Step 1: Add -Hy to both sides.

$Ax + Hy - Hy = K - Hy$
$Ax = -Hy + K$

Step 2: Divide both sides by A.

$\frac{Ax}{A} = \frac{-Hy+K}{A}$
$x = -\frac{Hy+K}{A}$
