Find the other endpoint of the line segment if one endpoint is (-3,6) and the midpoint is (-7,9), please explain how to solve it!!

as we know how to find midpoint.

the formula is = (x1 + x2/2 , y1 + y2/2 )

and the given values are one endpoint and midpoint so, just insert the given values in midpoint's formula..and u will get the value of other end point.

hope this answer helps you dear...take care and may u have a great day ahead!

if u have any doubt or dissatisfaction with the explanation...feel free to ask I will tell u more briefly.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
