Which number line represents -0.8 + 2.4

1.6

Step-by-step explanation:

if you are at -0.8 on a number line, you have to move 0.8 units to get to 0.  you then have to continue to move an additional 1.6 units to get a total of 2.4 units.

-0.8, -0.7, -0.6, -0.5, -0.4, -0.3,  -0.2, -0.1, 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9and so on.

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

answer:

f(5/2) = 10/3

i hope this you!
