find the resulting vector matrix of this matrix multiplication.

a = -21 and b = 15

Step-by-step explanation:

It is given a matrix multiplication,

To find the value of a and b

It is given that,

| 6  -5 |  *  | -1 |    =   | a |

|-3   4 |     |  3 |         | b |

We can write,  

a = (6 * -1) + (-5 * 3)  

 = -6 + -15

 = -2 1

b = (-3 * -1) + (4 * 3)

 = 3 + 12

 = 215

Therefore the value of  a = -21 and b = 15

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400
