35 ! what is the solution to the inequality? -2/3 (2x - 1/2)< = 1/5x - 1

-2/3(2x-1/2) ≤1/5x-1

Simplify the left side:

-4/3x+1/3 ≤1/5x-1

Subtract 1/5x from each side:

-23/15x + 1/3≤-1

Subtract 1/3 from each side:

-23/15x ≤-4/3

Divide both sides by -23/15:

X = -4/3 / -23/15

X ≥ 20/23

Convert to interval notation:

[ 20/23 , ∞)

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 !

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
