Let C represent the cost in dollars and R represent the revenue in dollars. What is the break-even point? Use a table to help if

krek1111 [17]

Answer:

(5,225)

Step-by-step explanation:

The break even point is when the cost equals the revenue.

C=R

15x+150=45x

150=30x

x=5

Plug this back into the original equations to get the y value.

15*5+150=225

or 45*5=225

What is the solution of 2m=-6n-5 when n=1,2,3

Travka [436]

Answer:

Step-by-step explanation:

Simplifying

2m + -6n + 5n + 3m = 0

Reorder the terms:

2m + 3m + -6n + 5n = 0

Combine like terms: 2m + 3m = 5m

5m + -6n + 5n = 0

Combine like terms: -6n + 5n = -1n

5m + -1n = 0

Solving

5m + -1n = 0

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add 'n' to each side of the equation.

5m + -1n + n = 0 + n

Combine like terms: -1n + n = 0

5m + 0 = 0 + n

5m = 0 + n

Remove the zero:

5m = n

Divide each side by '5'.

m = 0.2n

Simplifying

m = 0.2n

Answer:

Answer:

50.2

Step-by-step explanation:

$ut = \sqrt{ {6}^{2} + {5}^{2} } \\ \sqrt{36 + 25} \\ \sqrt{61 } \\ using \: cosine \: rule \\ cos \: u = \frac{ {5}^{2} + 61 - 36 }{2 \times 5 \times \sqrt{61} } \\ \\ = \frac{25 + 61 - 36}{78} \\ \\ = \frac{50}{78 } \\ \cos \: u = 0.64 \\ m \:u = 50.2$
