A triangle with vertices at A (20,-30), B(10,-15)and C (5-20) has been dilated with a center of dilation at the origin. The image of B, Point B’, Has the coordinates(2,-3). What is the scale factor of the dilation

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

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:

if you was gonna solve for a, a is a   < -12
