A tennis tournament has 128 competitors. Half of the competitors are eliminated each round. Part A: Write a function to represent the number of competitors that will be left after “x” rounds: y =
Part B: How many players will be left after 4 rounds?

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
