Answer:
x= -19
Step-by-step explanation:
2x-4x-9=29
-2x=29+9
x=38/-2
= -19
75/25 = 3
3x25 = 75
$25 per hour
Answer:
b)

Step-by-step explanation:
b) set up equations so they are equal to each other,



this is when f(x)=g(x) so our approximation was close.
c)solving it graphically is nearly impossible because the solution can be any value around the intersection. only way to be sure is to solve it symbolically.
Simplify the integrands by polynomial division.


Now computing the integrals is trivial.

where we use the power rule,

and a substitution to integrate the last term,

using the same approach as above.
