Answer:

Step-by-step explanation:

$Tan \ B =\frac{4}{3} = \frac{opposite \ side \ of B}{adjacent \ side \ of B}$

BC = 15 cm

3x = 15

x = 15/3 = 5

AB =4x = 4*5 = 20 cm

Pythagorean theorem,

AC² = AB² + BC²

= 20² + 15 ²

= 400 + 225

= 625

AC = √625 = 25 cm

AC = 25 cm

$Sin \ A = \frac{opposite \ side \ of \ angle A }{hypotenuse}\\\\ = \frac{BC}{AB}=\frac{15}{25}=\frac{3}{5}$

A cell phone company offers two plans for unlimited calling. The first plan has a monthly charge of $25 and 8.08 per text messag

Alja [10]

The answer is 125 messages.
Firstly the best thing to do is create two different equations.
1. y=25+.08x
2. y=20+.12x
Then you plug into Desmos and see at what point they cross. They cross at (125, 35).
Therefore for 125 text messages would cost 35$ for each plan.

Explain how to verify that 3(2x + 5) = 9 + 3x and x = –2 are equivalent equations.

aniked [119]

3 times (2x + 5) is 6x + 15.

6x + 15 = 9 + 3x.

Group by like terms. 6 = -3x

Divide to get x by itself. 6/-3 = -2

Thus -2 = x
