Which statement describes the system of equations?

x+2y=2
x-2y=-2
it has infinitely many solutions.
it has no solution.
it has one solution (0, 1).
it has one solution (4, -1).

(0,1) is the unique solution of the system .

Step-by-step explanation:

The given sets of equations are

x + 2y = 2

x - 2y = -2

Compare the equations with ax + by = c

Here, we get  a1 = 1, b1 = 2 and c1 = 2

and a2 = 1, b2 = -2 and c2 = -2

Now, as we can see ,

Here,

Hence, the system has UNIQUE SOLUTION.

And, (0,1) is the unique solution of the system

x + 2y = 0 + 2(1) = 2 = Right side

and x - 2y = 0 - 2(1) = -2 = Right side

how am i supposed to answer

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
