A certain translation takes point D(-3,10) to point D'(-12,21). What is the image of E(17,-9) under this translation?

(8, 2)

Step-by-step explanation:

Subtract the two D points.

(-12) - (-3) = -9

21 - 10 = 11

Then, use it to translate.

(17,-9)

(x - 9, y + 11)

= (8, 2)

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
