A saleswoman sells a​ dried-fruit mixture for ​$5.60 per pound and nuts for ​$14.25 per pound. She wants to blend the two to get a 15​-lb mixture that she will sell for ​$9.06 per pound. How much of each should she​ use? Solve using matrix

Nuts= 2.56

Dried fruit= 12.44

Step-by-step explanation:

x + y = 15

5.6 x + 14.25 y = 9.06 * 15

x   = 15 - y

5.6 x + 14.25 y = 134.9

5.6(15 - y) + 14.25 y = 134.9

84 -5.6y + 14.25y = 134.9

19.85y - 50.9

y = 2.56

x= 12.44

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
