On the track and field team, 38 of the members do the hurdles. Of the members who do the hurdles, 45 also do the long jump. If there are 40 members on the track team, how many do both the hurdles and the long jump?

12 members of the track team do both the hurdles and the long jump.

Step-by-step explanation:

As there are 40 members on the track team, if 3/8 of them do the hurdles, we have to divide 40 by 8 and the multiply the result by 3 to know the number. So, 40 / 8 is 5, and 5 x 3 is 15. Therefore, 15 members do the hurdles.

Of the members who do the hurdles, 4/5 of them also do the long jump. Using the same method, as 15 / 5 is 3, and 3 x 4 is 12, 12 members of the track team do both the hurdles and the long jump.

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
