First you have to solve for y on both equations
-4x -3y = 4
-3y = 4x + 4
y = -4/3 x + -4/3
4x - y = -4
-y = -4x -4
y = 4x + 4
If you graph these equations you will find out that the answer is C.
Answer:
-14
Step-by-step explanation:
40+25+25+70=160 Hope this helps! :)
Answer:
64 1/2
Step-by-step explanation:
6(1/4+5/2)-2
parethesis first 1/4 +5/2 make them the same denominator 1/4 + 10/4 = 11/4
then 6 or 6/1 time 11/4 = 66/4= 16 1/2 - 2 = 64 1/2 i havn't done fractions in awhile so im not a 100% certain
Check the picture below. Recall, is an open-top box, so, the top is not part of the surface area, of the 300 cm². Also, recall, the base is a square, thus, length = width = x.
so.. that'd be the V(x) for such box, now, where is the maximum point at?
now, let's check if it's a maximum point at 10, by doing a first-derivative test on it. Check the second picture below.
so, the volume will then be at
