Answer:-5.8
Step-by-step explanation:
DI/dx=-850x+45500
d2l/d2x=-850 so when dl/dx=0 it is an absolute maximum for l(x)...
dl/dx=0 only when:
850x=45500
x=53.53
x=54 years of age (rounded)
1-(-3)=4 slope= -4
4-5 =-1
y-y1=m(×-×1)
y-(-1)=-4(x-(-4))
y-(-1)=-4x+16
+1. +1
y= -4x+17

$36.12 is the better deal. The reason why is because if you divide $17.59 by 4 and then divide $36.12 by 9, you will find that the cost per shirt is cheaper for option two. Also if you multiply $17.59 by 2 you will find that for eight shirts it's $35.18, so just for a dollar more you get one more.
Answer:
z=44/3
Step-by-step
Subtract the numbers 52-12=40
3z-4=40
Add 4 to both sides
3z-4+4=40+4
SImplify
3z=44
Divide both sides by 3
3z/3 = 44/3
z=44/3 or decimal form= 14.66
