What color is it?? Please help

Red

Step-by-step explanation:

To solve this we can use substitution.

We know that y=4-x, so we can substitute "4-x" into anywhere that y appears in the first equation.

4-x=3x-8

Now we can move the variables to one side and the numbers to the other.

We can do that by adding x to both sides.

4=3x-8+x

Now, let's add 8 to both sides.

4+8=3x+x

Combine like terms.

12=4x

x=3

Now, we can plug that back into the equation to find y.

y=3(3)-8

y=8

y=1

So our answer is (3,1)

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!
