18. Elijah and Thomas are working together toward improving their times on the 100-yard dash. Their best time, in seconds, are recorded by the coach every week. Week 1 2. 3 4 5 6 7 14.25 13.45 13.62 12.77 12.83 11.97 12.74 Elijah Thomas 12.65 12.48 12.10 12.36 11.84 12.17 12.04 A. Use the scores in the table below to find linear models for each boy's progress. B. If these trends continue, predict when the two boys will have the same time.

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
