First, let's get a clear visual of her weekly income:
Saturday hrs. of work = 6
Monday hrs. of work = 4
Dog walker salary per. week = $20
Weekly income = $130
We can rule out A, since it doesn't even include the amount of income she earns on Monday.
We can also rule out D, since it doesn't include the amount of income she earns on Saturday.
Lastly, we can rule out B, since it doesn't include the mount of income she earns while walking dogs.

Thanks to the rules of elimination, we can concur that the correct answer is C. It includes all components of income during Amy's week, formulating a strong equation to determine the value of h.

Hope this helps. :)

The answer is the third one
-the hours are unknown so its 6+4h
the total is 130 and she earns an extra 20 dollars so
(6+4)h+20=130

write an equation for the line that is perpendicular to the given line and passes through the given point y-3=8/3(x+2);(-2,3)

Stolb23 [73]

Answer:

$y-3=-\frac{3}{8} (x+2)$

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point (8,1) and a slope from the equation. We will chose point-slope since we have a point and slope.

Point slope: $y-y_1=m(x-x_1)$

$m\neq \frac{8}{3}$ in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is $m=-\frac{3}{8}$ .
