Answer:
false
Step-by-step explanation:
This is a solution to the first equation because
5+-9=-4
-4=-4
however, if you plug it into the next equation, it becomes false.
5--9=4
14=4
this does not make sense.
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 is
<h2>
![y = - \frac{2}{5} x - 2 \\](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B2%7D%7B5%7D%20x%20-%202%20%5C%5C%20)
</h2>
Step-by-step explanation:
To find an equation of a line when given the slope and a point we use the formula
![y - y_1 = m(x - x_1)](https://tex.z-dn.net/?f=y%20-%20%20y_1%20%3D%20m%28x%20-%20%20x_1%29)
where
m is the slope
( x1 , y1) is the point
From the question the points is (5, -4) and slope - 2/5
The equation is
![y + 4 = - \frac{2}{5} (x - 5) \\ y + 4 = - \frac{2}{5} x + 2 \\ y = - \frac{2}{5} x + 2 - 4](https://tex.z-dn.net/?f=y%20%2B%204%20%3D%20%20-%20%20%5Cfrac%7B2%7D%7B5%7D%20%28x%20-%205%29%20%5C%5C%20y%20%2B%204%20%3D%20%20-%20%20%5Cfrac%7B2%7D%7B5%7D%20x%20%2B%202%20%5C%5C%20y%20%3D%20%20-%20%20%5Cfrac%7B2%7D%7B5%7D%20x%20%2B%202%20-%204)
We have the final answer as
![y = - \frac{2}{5} x - 2 \\](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B2%7D%7B5%7D%20x%20-%202%20%5C%5C%20)
