The cost C (in dollars) of building a house is related to the number k of carpenters used and the number e of electricians used by† C(k, e) = 15,000 + 50k2 + 60e2. If k = e = 19, compare the effects of increasing k by one unit and of increasing e by one unit.

look at the photo

find k when e = 15

Look at the other pic

inst rate of carpenters with 15 electricians: decreasing at 0.476 carpenters per electrician

Step-by-step explanation:

b.an increase in a causes b to decrease

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,
