Answer:
f(g(x)) =

Step-by-step explanation:
f(x) =

g(x) = 8x - 13
f(g(x) =


Above, I changed the fraction form of x and y into exponential form so it is easier to see the differentiation. Now, we can differentiate:

Now that we have dy/dx, we can plug in the x, which is 4, and the y, which is 4/19. We know these values of x and y because your question stated y(4) = 4/19.
The answer is D. The family would want to sale more or equal to what the cost is. 10,100 is 54 dollars too short how ever 10,200 is 46$ over what they need which is what they need.
Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
The formula of a slope:

From the graph we have two points (-5, -1) and (-2, -3).
<em>Look at the picture</em>.
Calculate the slope:

Put it to the equation in slope-intercept form:

We can't read the y-intercept from the graph. Therefore put the coordinates of the point (-5, -1) to the equation and calculate <em>b</em>:

<em>subtract 10/3 from both sides</em>

Finally:

Answer:
y=4
x=-3
Step-by-step explanation:
4(-3)-9y=-48
-12-9y=-48
-9y=-36
y=4
x=-3
