consider the function f(x) = -2/3x + 5.

what is f(5/2)?
enter your answer in the box as a simplified fraction.

f(5/2) = ?

3 1/3.

Step-by-step explanation:

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

= -10/6 + 5

= 5 - 5/3

= 10/3

= 3 1/3.

10/3 or 3 1/3

Step-by-step explanation:

To solve this problem, we first combine our numbers which in this case are 5/2 which add to function f (x)

Now we have f(x) = -2/3(5/2) + 5.

= -10/6 +5

= -10+30/6

=20/6 = 10/3

= 3  1/3

To solve from here, we need to subtract 10 from the 30 of the equation. Whatever we do to one side,  we get 8.

Now we have f(5/2) = 10/3  or 3 1/3

This means that f(5/2) = 10/3  or 3 1/3

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
