Which graph shows the solution set of x-9/7x+2<=0
S_A_V [24]
For this case we have the following inequality:
 \frac{x-9}{7x+2}  \leq 0
 Solving for the numerator we have:
 x-9 \leq 0
 x  \leq 9
 Solving for the denominator we have:
 7x+2\ \textgreater \ 0
 7x\ \textgreater \ -2
 x \ \textgreater \   \frac{-2}{7}
 Therefore, the solution is given by:
 \frac{-2}{7} \ \textless \  x  \leq 9
 The graph that shows this solution is the graphic number 3.

Can anyone help me with the answer to this please?
stiks02 [169]

Answer:

Step-by-step explanation:

To find the inverse function switch variables out and solve for y

If

y=(x+3)/x swap variables to get

(y+3)/y=x then solve for y

y+3=yx

y-yx+3=0

y-yx=-3

y(1-x)=-3

y=-3/(1-x)

y=3/(x-1)

Find the vertex of the function h(x) = x2 – 4x – 21
lakkis [162]

Answer: (2, -25)

Step-by-step explanation:

The x coordinate of the vertex is x=-\frac{-4}{2(1)}=2.

When x=2, h(2)=2^2 - 4(2)-21=-25.

So, the vertex is (2, -25).

Let us consider the image on the left that is the image in which 1 and 2 , 3 and 4 are connected as image 1 and the other as image 2.

1. All Vertices are connected by the least amount of edges. True

2. Vertex 1 and 2 are not connected. This is false for image

1 and true for image 2

3.  Vertex 3 and 4 are not connected. This is false for image

1 and true for image 2

4. You can get to Vertex 1 from Vertex 4 by going through Vertex 3. This is true for image 1
