Guys plzz help lol and thanks

B

Step-by-step explanation:

the key says the solid black dots are negative numbers

there is 3 of them

(-3)

the white dots are normal numbers

there are 5

they are being added together

5+(-3)

5-3

2

its B

also, you are so lucky its only 72F where you live I am so hot here it is like 98.

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 !
