Answer:
Step-by-step explanation:
A. Price is 1.75
Total revenue, if number of galsses equals X is 1.75X
Total cost function of X glasses of lemonade is 25+0.1X
Profit function is Revenue - Cost, P=1.75X-25-0.1X=1.65X-25
C. Marginal profit= d/dx(1.65x-25) = 1.65-0=1.65
X=300 glasses, P'(300)=1.65
X=700 glasses, P'(700)=1.65
Answer: 5.6
===================================
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(B) = AB/BC
cos(62) = AB/12
12*cos(62) = AB
AB = 12*cos(62)
AB = 5.63365875
AB = 5.6
Answer:
<em>x= -6</em>
Step-by-step explanation:
so i'm thinking 1 solution.
<u><em>(let me know if i'm wrong)</em></u>
Answer:
y= -2/3x - 2 and y= -2/3x+2
Step-by-step explanation:
There are two standard forms given
1) 2x + 3y= -6
2) 2x + 3y = 6
Equation of a graphed line is written as y=mx+c
Step 1: Make y the subject on the left side. On the right side, make sure that x comes first.
1) 2x + 3y= -6
3y = -6 - 2x
y = <u>-6-2x</u>
3
y = -2x/3 - 2
2) 2x + 3y = 6
3y = 6 - 2x
y = <u>6-2x</u>
3
y = -2x/3 + 2
