Select the correct answer from each drop-down menu. The scatter plot shows the average cost of peaches against the quantity sold for different farmers.

The equation of the line is . When the cost of peaches is $4, about pounds of peaches are sold.

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
