Hey there! How are you today?

First, let's understand what we're doing.
We are dealing with subtracting functions.
Always be sure to know what you're subtracting by what - you don't want to misinterpret the situation and mess up over a minor error.

Now, let's get to the problem.

f(x) = 4x + 1
g(x) = x^2 - 5

Find (f - g)(x).

By "Find (f - g)(x)", we mean to subtract f(x) by g(x).

Remember what f(x) is and what g(x) is.

So, let's set up our equation.

4x + 1 (Remember to subtract like-terms)
-x^2 + 5
——————
-x^2 + 4x + 6 is your solution.

Answer choice "D.)" matches our solution.

I hope this helps!

Answer:

$\dfrac{x}{3}+\dfrac{3}{y}$

Step-by-step explanation:

<u>Given fraction</u>:

$\dfrac{xy+9}{3y}$

$\textsf{Apply the fraction rule} \quad \dfrac{a+b}{c}=\dfrac{a}{c}+\dfrac{b}{c}:$

$\implies \dfrac{xy}{3y}+\dfrac{9}{3y}$

Rewrite 9 as 3 · 3:

$\implies \dfrac{xy}{3y}+\dfrac{3 \cdot 3}{3y}$

Cancel the common factor y in the first fraction and the common factor 3 in the second fraction:

$\implies \dfrac{x\diagup\!\!\!\!y}{3\diagup\!\!\!\!y}+\dfrac{\diagup\!\!\!\!3 \cdot 3}{\diagup\!\!\!\!3y}$

$\implies \dfrac{x}{3}+\dfrac{3}{y}$

A rectangle is placed around a semi circle as shown below. The width of the rectangle is 7yd. find the area of the shaded region

Nady [450]

Answer:

21.07 yd^2

Step-by-step explanation:

The width of the rectangle is also the radius of the semicircle. The length of the rectangle is 2 radii, or 14 yd.

The area of the shaded region is the same as the area of the semicircle subtracted from the area of the rectangle.

area of shaded region = area of rectangle - area of semicircle

A = LW - (1/2)(pi)r^2

A = 14 yd * 7 yd - (1/2)(3.14)(7 yd)^2

A = 98 yd^2 - (1.57)(49 yd^2)

A = 98 yd^2 - 76.93 yd^2

A = 21.07 yd^2
