216.4 is the total cost added up.
198.77 would be the subtraction of the answer above with the hardware supplies but subtraction would be wrong so you'd have to divide, dividing would get you to 0.0814, the you'll have to divide the decimal by 100 giving you 0.0815.
Do the same steps above but with the paint and hardware.
52.91/216.4 gives you 0.244501, rounded up would give you 0.000245.
Add those two totals together to get your answer, 0.081745.
Sorry if I'm wrong. Hope this helps!

Answer:
The answer to your question is The point (-3, 2) is not a solution
Step-by-step explanation:
Inequality
- 4x - 10y < - 9
-point (-3, 2)
Process
1.- To solve this problem, just substitute the point in the inequality and simplify
a) Substitution
-4(-3) - 10(2) < - 9
b) Simplification
12 - 20 < - 9
c) Result
- 8 < - 9
This is false, -8 > -9
Y = 1/2x - 3. Slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So the perpendicular line will have a slope of -2.
y = mx + b
slope(m) = -2
(1,-1)...x = 1 and y = -1
now we sub and find b, the y int
-1 = -2(1) + b
-1 = -2 + b
-1 + 2 = b
1 = b
so ur perpendicular equation is : y = -2x + 1
Answer:
A. reflection across the y-axiss
Step-by-step explanation:
Given:
The locations of the two points are (-4 , 8) and (-4 , -8).
To find:
The relation between two points.
From the given points (-4, 8) and (-4 , -8), it is clear that the y-coordinates are same but the sign of x-coordinates are opposite.
If a figure is reflected across the y-axis, then we change the sign of x-coordinate and the y-coordinates remain same, i.e.,
→
For (-4,8)
→ 
So, it is reflection across the y-axis.
Therefore, the correct option is A.
