The two triangles displayed are scaled copies of one another. Two triangles. Triangle on left, left side = x, bottom side = 4. Triangle on right, left side = 25, bottom = 10.

Type the answers into the boxes below.

a. What is the scale factor?

b. What is the value of x?

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

step-by-step explanation: yes

16.9 times 2.85

step-by-step explanation:

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.
