r(b) = 12b
c(b) = 4 + 3.3b
I think profit is revenue minus the cost, so p(b) = r(b) - c(b)
= 12b - (4 + 3.3b)
12b - 4 - 3.3b //Combine like terms
8.7b - 4
Answer: D
//Hope it helps and it's right.
Answer:
The lines intersect once at (2, −1).
A graphic solution to a system of equations is only as accurate as the scale of the paper or precision of the lines. At times the point of intersection will need to be estimated on the graph. When an exact solution is necessary, the system should be solved algebraically, either by substitution or by elimination.

thanks for the points !!! ;)
Step-by-step explanation:
The constant is 15, divide 45 by 3 then you’ll get 15. multiply 15 with the minutes and you’ll get the sit-ups
Answer:
Part 1) The exact value of the arc length is \frac{25}{6}\pi \ in
Part 2) The approximate value of the arc length is 13.1\ in
Step-by-step explanation:
ind the circumference of the circle
The circumference of a circle is equal to
C=2\pi r
we have
r=5\ in
substitute
C=2\pi (5)
C=10\pi\ in
step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion
\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in
Find the approximate value of the arc length
To find the approximate value, assume
\pi =3.14
substitute
\frac{25}{6}(3.14)=13.1\ in
