Determine the quadrant(s) in which (x, y) could be located. (Select all that apply.)
djyliett [7]

Answer: D. Quadrant IV

Step-by-step explanation: Numbers with a positive or negative sign are referred to be directed numbers. These numerals are easily found on the number line. 2, 5, -1, -3, -7, 9, and so on are some examples.

As a result: x > 0 and y 0 are both true.

Consider the case of specific directed numbers for x and y. Assume x = 5 and y = -2, and the following is true: (5, -2). In a Cartesian plane, this point can be found in the fourth quadrant.

As a result, in a Cartesian plane, the quadrant in which (x, y) might be found is Quadrant IV.

Is this equation an identity? (2x+1)^2-(x+1)^2=3(x+1)^2-1
sergey [27]

Answer:

See below, please

Step-by-step explanation:

Left side

{(2x + 1)}^{2}  -  {(x + 1)}^{2}

= (4 {x}^{2}  + 4x + 1) - ( {x}^{2}  + 2x + 1)

= (4 {x}^{2}  -  {x}^{2} ) + (4x - 2x) + (1 -1 )

= 3 {x}^{2}  + 2x

Right side

3 \times  {(x + 1)}^{2}  - 1

= 3 \times ( {x}^{2}  + 2x + 1) - 1

= 3 {x}^{2}  + 6x + 3 - 1

= 3 {x}^{2}  + 6x + 2

After compared with both sides, we can make a conclusion that

This equation isn't an identity.
