Answer:

718\ min

Step-by-step explanation:

Let

x ----> the number of minutes

y ----> the total charge in dollars

we know that

For x>700 min

y=0.45x+40

so

For y=48.10

substitute

48.10=0.45x+40

Multiply by 100 both sides

4,810=45x+4,000 ----> equation without decimals

solve for x

45x=4,810-4,000\\45x=810\\x=18\ min

To find out the total minutes we need to sum

18\ min+700\ min=718\ min

Please help! Correct answer only, please!
MAXImum [283]

Answer:

B)

Step-by-step explanation:

If two square matrix, with same dimensions, are inverse of one another, their product will always be the identity matrix with the same dimensions.

The matrix A and B are 2x2, so the result of the product A * B is a 2x2 identity matrix, that is represented as follows:

I = [1 0 ; 0 1]

(First line: 1 0, second line: 0 1)

So the correct option is B)
