Answer:

1. 0.90m + 3 > 0.60m + 4; 2. 4.50v + 8.50 < 6.00v  

Step-by-step explanation:

1. Taxis

  Let A = cost of Taxi A

 and B = cost of Taxi B

Then A = 0.60m + 4

 and B = 0.90m +3

If B > A, then

0.90m + 3 > 0.60m + 4

2. Video games

  Let A = monthly cost at Store A

 and B = monthly cost at Store B

Then A = 4.50v + 8.50

  and B = 6.00v

If A < B, then

4.50v + 8.50 < 6.00v

Matrix question help needed
kramer

The required matrix is:

\left[\begin{array}{ccc}-25&17&0\\8&-1&3\\\end{array}\right]

Step-by-step explanation:

We need to apply elementary row operation -2R₂+3R₁ tothe matrix:

A=\left[\begin{array}{ccc}-3&5&2\\8&-1&3\\\end{array}\right]

Multiplying Row 2 with -2 and Row1 with 3 and adding,

-9 15 6

-16 2 -6

----------

-25 17  0

After applying this operation, Row 1 will be changed while Row 2 will remain same because we get -2R₂+3R₁ -> R₁

The required matrix is:

\left[\begin{array}{ccc}-25&17&0\\8&-1&3\\\end{array}\right]

Keywords: Matrices, elementary row operation

HELP Pythagorean theorem
padilas [110]

Answer:the unknown leg is 7.5

Step-by-step explanation:

The given right angle triangle has a hypotenuse, a known leg and an unknown leg.

From the triangle,

The hypotenuse is 9

The known leg is 5

The unknown leg is x

The formula for Pythagoras theorem is expressed as

Hypotenuse^2 = opposite side^2 + adjacent side^2

Hypotenuse^2 = known leg^2 + unknown leg^2

Therefore

9^2 = 5^2 + x^2

81 = 25 + x^2

x^2 = 81 - 25 = 56

x = √56 = 7.5
