If g(x) = x+1/ x-2 and h (x) =4 - x , what is the value of ( g*h) (-3)?
Lapatulllka [165]

<u>Answer:</u>

g (h (x) ) = 5/8

<u>Step-by-step explanation:</u>

We are given the following two functions and we are to find the value of g ( h ( - 3 ) ):

g ( x ) = \frac { x + 1 } { x + 2 }

h ( x ) = 4 - x

Firstly, we need to find the function :

g ( h ( x ) ) = \frac { ( 4 - x + 1 ) } { ( 4 - x - 2 ) } = \frac { 5 - x } { 2 - x }

Now substituting the value x=-3 in it:

g ( h ( x ) ) = \frac { 5 - (-3) } { 2 - (-3) }

g (h (x) ) = 5/8

How do you calculate the x-intercept of a line written in Standard Form?
serious [3.7K]
To calculate the x-intercept of a line written in standard form you simply remove the "y" and solve for x. And you remove the "x" when solving for y.

y=0 , solve for x
x=0 , solve for y


Here is an example: (solving for x)

2x + 3y = 6
2x + 3(0) = 6
2x = 6
2x/2 = 6/2
x = 3

Here is an example: (solving for y)

2x + 3y = 6
2(0) + 3y = 6
3y = 6
3y/3 = 6/3
y = 2

Find the slope of the line through the given points.(-4,7) and (-1,-3)Is the slope increasing or decreasing?
galina1969 [7]

• The following formula can be used to find the slope of a line:

m=\frac{y_2-y_1}{x_2-x_1}

These points are on the line:

(x_1,y_1);(x_2,y_2)

Given the following points:

\mleft(-4,7\mright);(-1,-3)

Then, you can set up that:

\begin{gathered} y_2=-3_{} \\ y_1=7 \\ x_2=-1 \\ x_1=-4 \end{gathered}

Therefore, substituting values into the formula and evaluating, you get:

\begin{gathered} m=\frac{-3-7}{-1-(-4)} \\  \\ m=\frac{-10}{-1+4} \\  \\ m=-\frac{10}{3} \end{gathered}

• As you can notice, the slope is negative. Therefore, you can determine that it is decreasing.

Therefore, the answers are:

• Slope of the line:

m=-\frac{10}{3}

• It is decreasing.

Find the area of the figure.
skelet666 [1.2K]

Answer:

132 cm^2

Step-by-step explanation:

7x4 is 28 for the top rectangle.

Bottom left triangle is bh/2 which here is 8x6/2 which is 24.

The same goes for the bottom right triangle.

Lastly the middle triangle is 7*8 which is 56.

Hence, 56+28+24+24=132!

Hope it helped!
