Consumer demand. suppose that 6.5 million lb
of coffee are sold when the price is $12 per pound,
and 6.0 million lb are sold when it is $15 per
pound. og
a) find a linear function that expresses the
amount of coffee sold as a function of the
price per pound.
b) use the function of part (a) to predict how
much consumers would be willing to buy at a
price of $6 per pound.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

step-by-step explanation:

what are the statements? and what do you mean by "216 2 1 6"?

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

its very big question plz make it small
