There aer infinite numbers
to make it easier we can solve for y
2x-8y=-4
x-4y=-2
-4y=-x-2
y=(1/4)x+(1/2)
some values aer
x=0, y=1/2
x=-2, y=0
etc
Answer:
The dispensing unit worth today: $21,000
Step-by-step explanation:
If we assume that a year has elapsed since the dispensing unit was purchased, then we know that it has lost 25% of its initial value.
If its initial value was 28,000 then we calculate 25% of 28,000

Now we subtract 7000 from the initial amount to get the current value.
The current value is:

USE THE ORDER OF OPERATIONS (PEMDAS) in all questions.
PEMDAS is:
Solve the parentheses first
Then the exponents
Then multiplication and division (from left to right, what ever comes first)
Lastly, addition and subtraction (from left to right, what ever comes first in the equation)
10) b. 60
11) b. 100
12) c. 384

Answer: a = -4
Step-by-step explanation:
Yes it is a solution because if you take the equation and plug the point in for the x and y :
4 (2) + 3 (3) < 20
8 + 9 < 20
17 < 20
which is true
10 (2) + (3) > 10
20 + 3> 10
23>10
which is also true
