Step-by-step explanation:

f(x) = 5x - 4

You have to replace 9 to every position x is in.

f(9) = 5×9 - 4

f(9) = 45 - 4

f(9) = 41

Given that f(x) = x2 – 3x – 28 and g(x) = x - 7, find

gregori [183]

Answer:

$(f-g)(x)=x^2-4x-21$

Step-by-step explanation:

We are given the two functions:

$f(x)=x^2-3x-28\text{ and } g(x)=x-7$

And we want to find:

$(f-g)(x)$

This is equivalent to:

$=f(x)-g(x)$

Substitute:

$=(x^2-3x-28)-(x-7)$

Distribute:

$=x^2-3x-28-x+7$

Rearrange:

$=(x^2)+(-3x-x)+(-28+7)$

Hence:

$(f-g)(x)=x^2-4x-21$

Which represents a measure of volume? O 5 cm O 5 square cm 05 cm 05 cm

Elena-2011 [213]

Answer:

a) 5 $cm^{3}$

Step-by-step explanation:

Bodies have three dimensions (width, height and depth). Measuring volume is calculating the number of cubic units that can fit inside.

When raising to 3, these dimensions are included and therefore 5 $cm^{3}$ is a measure of volume.
