Determine the quadrant(s) in which (x, y) could be located. (Select all that apply.) x > 0 and y < 0
Quadrant I
Quadrant II
Quadrant III
Quadrant IV
none of these

D. Quadrant IV

Step-by-step explanation:

Directed numbers are numbers with either a positive sign or a negative sign. These numbers can be located easily on the number line. Examples are: 2, 5, -1, -3, -7, 9 etc.

Given that: x > 0 and y < 0

For example, let us consider specific directed number for x and y. Let x = 5 and y = -2, so that; (5, -2). This point can be located in the fourth quadrant of a Cartesian plane.

Therefore considering a Cartesian plane, the quadrant in which (x, y) could be located is: Quadrant IV.

b

step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
