What is the distance between (-7,0), (-2,-4)

6.4 units

Step-by-step explanation:

sqrt (x2 - x1)^2 + (y2 - y1)^2

sqrt (-2 - (-7)^2 + (-4 - 0)^2

sqrt (5)^2 + (-4)^2

sqrt 25 + 16

sqrt 41

6.403124237

i dont get it. where are the "descriptions"?

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
