Answer:
y = c/b - (A x)/b
Step-by-step explanation:
Solve for y:
A x + b y = c
Hint: | Isolate terms with y to the left hand side.
Subtract A x from both sides:
b y = c - A x
Hint: | Solve for y.
Divide both sides by b:
Answer: y = c/b - (A x)/b
Answer:
Point D
Step-by-step explanation:
AD and CD are a line
The intersection of two lines is a point
The two lines intersect at point D
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)
