A is the answer. Ask if you need me to explain.
-7 - 3x = 9x(x + 2)
Standard Form:
-9x^2 - 21x - 7 = 0
<span>Differentiate implicitly:
</span>
<span>
Solve for y
</span>
<span>When the tangent is parallel to the x-axis we have y'=0, so we must solve
</span>
<span>To find the actual value of x we plug this expression for y into the original equation
</span>
<span>Plugging this into the formula for y above gives the points
</span>
<span>which is where our tangent will be parallel to the x-axis.</span>

Answer:
10
Step-by-step explanation:
The total earnings for X visits by plumber X and Y hours worked by plumber Y is ...
41X +46Y = total earnings
41X +46(7) = 732 . . . . . for the given values
41X = 410 . . . . . . . . . . . subtract 322
X = 10 . . . . . . . . . . . . . . divide by 41
Plumber X made 10 visits.
