Answer:

40

Step-by-step explanation:

You can find y intercept by looking at the end of the equation, that’s what’s added. So +40 is the y intercept

The y intercept in this equation represents the one-time registration fee

The y intercept should be 40 as it’s the base you pay for the membership, and another $15 per month.

I need help with this one pls!

Hi there!

\large\boxed{b = \frac{a}{ac - 1}}

We can begin by making each fraction have a common denominator:

If we make each have a common denominator of ab, we get:

\frac{b}{ab} + \frac{a}{ab} = c

Simplify:

\frac{a + b}{ab}  = c

Multiply both sides by ab:

a + b = cab

Move b to the opposite side:

a = cab - b

Factor out b:

a = b(ac - 1)

Divide by (ac - 1):

\frac{a}{ac - 1} = b
