A phone company offers two monthly plans. Plan A costs $12 plus an additional $0.16 for each minute of calls. Plan B costs $29 p

Answer:

425 min
$80

Step-by-step explanation:

The equation to reflect the monthly plans:

Plan A f(x) = 0.16x + 12
Plan B g(x) = 0.12x + 29

We need to find the value of x when f(x) = g(x):

0.16x + 12 = 0.12x + 29
0.16x - 0.12x = 29 - 12
0.04x = 17
x = 17/0.04
x = 425 minutes

The cost is:

$0.16*425 + $12 = $80

If possible step by step explanation. thank you!

elixir [45]

Answer:

Step-by-step explanation:

$\frac{(3x^{2} )^\frac{1}{2} }{3^\frac{1}{2} } =3$

$(3x^2)^\frac{1}{2} = 3^\frac{1}{2} x$

Remember that $\frac{x^b}{x^c} =$ x^(b-c)

Using that $\frac{3^\frac{1}{2}x }{3^\frac{1}{2} }$ =3^(1/2x-1/2)=3^((x-1)/2)

$3^\frac{x-1}{2} =3^1$

So we can say: $\frac{x-1}{2} =1$ , because the bases are the same

We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.
