Which represents the distance between A(2, 3) and B(-1,-1)?

5 units

Step-by-step explanation:

(x1, y1) =A(2,3)

(x2,y2) =B(-1,-1)

Using distance formula,

AB^2 = (x2-x1) ^2 +(y2-y1) ^2

=(-1-2)^2 +(-1-3)^2

=9+16

=25

Therefore, AB=5 units

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

a)(x-2)^2+(y-1)^2=9
