Answer:
-3/5
Step-by-step explanation:
the customary way to determine the slope of a linear equation such as this one is to solve the equation for y:
-3x-5y=15 becomes -5y = 15 + 3x after 3x is added to both sides of the original equation.
Solving both sides of this latest result by -5 results in
y = -3 - (3/5)x
The coefficient of x (which here is 3/5) is the slope of this equation.

Answer:
D
Step-by-step explanation:
Identify which of the following tables shows the number of triangles and the total perimeter for the following pattern. Use the table to predict the perimeter for 5 triangles.
C(x) = 200 - 7x + 0.345x^2
Domain is the set of x-values (i.e. units produced) that are feasible. This is all the positive integer values + 0, in case that you only consider that can produce whole units.
Range is the set of possible results for c(x), i.e. possible costs.
You can derive this from the fact that c(x) is a parabole and you can draw it, for which you can find the vertex of the parabola, the roots, the y-intercept, the shape (it open upwards given that the cofficient of x^2 is positive). Also limit the costs to be positive.
You can substitute some values for x to help you, for example:
x y
0 200
1 200 -7 +0.345 = 193.345
2 200 - 14 + .345 (4) = 187.38
3 200 - 21 + .345(9) = 182.105
4 200 - 28 + .345(16) = 177.52
5 200 - 35 + 0.345(25) = 173.625
6 200 - 42 + 0.345(36) = 170.42
10 200 - 70 + 0.345(100) =164.5
11 200 - 77 + 0.345(121) = 164.745
The functions does not have real roots, then the costs never decrease to 0.
The function starts at c(x) = 200, decreases until the vertex, (x =10, c=164.5) and starts to increase.
Then the range goes to 164.5 to infinity, limited to the solutcion for x = positive integers.
His total pay was $997.
We use the equation
y=150+0.14x
to represent this, were y is his total pay and x is the amount of sales he has. Using our information, we have
y=150+0.14(6050) = 150+847 = 997
