Answer:
The solution to the system is (-1, 3).
Step-by-step explanation:
The (x, y) value that is the solution to the system is the point that is on both lines. That point is the point where the lines intersect. The coordinates can be read from the graph as ...
... x = -1, y = 3
So, the (x, y) ordered pair is (x, y) = (-1, 3).
Answer:
13
Step-by-step explanation:
Y = 25 - 3x
X = 4
Y = 25 - 3(4)
Y = 25 - 12
Y = 13
Answer:
y=-x-3
Step-by-step explanation:
x+y=-3
then you subtract the x to get y alone so,
answer
y=-x-3
1800/3 = 600
Every pound covers 600 square feet
8400/600 = 14
<span>14/4 = 3.5 (round up) so it would become 4.

You would need 4 bags.
