If you subtract 16 from my number and multiply the difference by -3 the result is -57 what is my number

35

Step-by-step explanation:

-57 divided by -3=19

19+16=35

hope this helps:)

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
