4 0

Answer:

a = -21 and b = 15

Step-by-step explanation:

It is given a matrix multiplication,

<u>To find the value of a and b </u>

It is given that,

| 6  -5 |  *  | -1 |    =   | a |

|-3   4 |     |  3 |         | b |

We can write,  

a = (6 * -1) + (-5 * 3)  

 = -6 + -15

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

store a sells 12 juices bottles for $4 and store B sells 18 juice bottles for $6. Are the ratew equivalent? explain your reason
Elza [17]
First, you'll have to find how much it costs for one bottle of juice.
Store A- 4/12= 0.33 So one bottle of juice costs 33 cents.
Store B- 6/18= 0.33 So one bottle of juice costs 33 cents.

Yes, the rates are equivalent because one bottle of juice costs the same from each store.
