Mai's coffee shop makes a blend that is a mixture of two types of coffee. type a coffee costs mai $4.10 per pound, and type b coffee costs $5.75 per pound. this month's blend used twice as many pounds of type b coffee as type a, for a total cost of $561.60 . how many pounds of type a coffee were used?

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

no this is a nonlinear negative
