1. Solve the following linear equation and state the value/s of x. Round to the

2(x - 5) + 4 = 2(x-3)

Answers

Answer:

No Solution

Step-by-step explanation:

2(x - 5) = 2(x - 3)

2x -10 = 2x -6  When we subtract 2x from both sides we are left with a false statement.

Which graph represents the function g(x) = 3/(x+2) -4?

Answers

Answer:

x=-2, y=-4

Step-by-step explanation:I took the test on k12

The required graph of the given function g(x) = 3/(x+2) -4 is given in the image attached below,

Given that,
The graph for the function g(x) = 3/(x +2) - 4 is to be determined.

What is a graph?

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
g(x) = 3/(x+2) - 4
Since the function has an inverse operator as 1 / (x + 2) the graph for the given function shown in the graph,

Thus, the required graph of the given function g(x) = 3/(x+2) -4 is given in the image attached below,

What’s the value of x?

Answers

14 sorry if I’m wrong

Answer:

6*15 = 5(x+5)

90 = 5x + 25

65 = 5x

x = 13

Step-by-step explanation:

I've gone ahead and labeled some points.

There is a formula that says PA*PB = PC*PD, this is what you use.  If you would like me to show why this works I would be happy to.

So what we have is PA = 6, PB = 9+6 = 15, PC = 5 PD = 5+x so let;s writ ethe formula with these values

6*15 = 5(x+5)

90 = 5x + 25

65 = 5x

x = 13

EDIT: Here is the explanation for the formula

If you form triangles PCB and PAD you can find angle D and angle B are the same, because they are inscribed angles that intersect the same arc of the circle.  Also angle P is the same on both triangles since they are the same angle, so this means both triangles are similar.

This means DA is similar to BC, AP is similar to CP and PD is similar to PB. Similar sides means if you can multiply one side by a number to get to its similar side, then you can multiply all sides by that value to get all sides of that similar triangle.  

This also means if you divide one side by its similar side you get the scale value, so this means if you do it to two different sets of similar sides you get the same number

[tex]\frac{PA}{PC}=\frac{PD}{PB}\\PA*PB = PC*PD[/tex]
