Answer:

f(5) = 2(5) - 4

f(5) = 10 - 4

f(5) = 6

Step-by-step explanation:

To find f(5), replace the x in the equation with its given value 5:

f(x) = 2x - 4

f(5) = 2(5) - 4

f(5) = 10 - 4

f(5) = 6

When the problem gives you f(5), it is basically telling you to plug in 5 into x in the equation so ...

f(5) = 2(5) - 4
f(5) = 10 - 4
f(5) = 6

Hope this helps!

What is the volume of the prism?

mezya [45]

Answer:

40 $\frac{5}{8}$ $cm^{3}$

Step-by-step explanation:

The figure is a rectangular prism, so the formula would be Volume = length x width x height.

length = 6 $\frac{1}{2}$ cm

width = 2 $\frac{1}{2}$ cm

height = 2 $\frac{1}{2}$ cm

If you plug everything you have in the problem into the volume equation, you would get : Volume = 6 $\frac{1}{2}$ cm x 2 $\frac{1}{2}$ cm x 2 $\frac{1}{2}$ cm.

Without a calculator, I would first turn the mixed numbers into improper fractions.
