Answer:

$\boxed{x=-\frac{5}{2}}\\$

Step-by-step explanation:

To begin, get the variable on one side of the equation - preferably the left for standard solution notation (for this equation, it is easier to place it on the right side to avoid negative values). Do this by subtracting 2x from both sides of the equation. Then, subtract 11. Finally, divide by 4 and get the answer in terms of x.

1 + 2x = 6x + 11

1 = 4x + 11

-10 = 4x

$\boxed{x=-\frac{5}{2}}$

Answer:

x = -5/2

Step-by-step explanation:

1+2x=6x+11

Subtract 2x from each side

1+2x-2x=6x-2x+11

1 = 4x+11

Subtract 11 from each side

1-11 = 4x

-10 =4x

Divide by 4

-10/4 = 4x/4

-5/2 =x

A car company is testing how well its cars handle skidding to a complete stop after hitting the brakes while going at different

Masja [62]

Answer:

D SD= sqrt(22.5D) Average Rate of Change

47 32.52

50 33.5 0.34

56 35.50 0.33

60 36.74 0.31

62 37.35 0.305

65 38.24 0.3

In the context of this problem, the average rate of change is the rate at which the car decelerates as it skids. As the distance that the car skids increases, the rate at which the car decelerates decreases at a gradual rate.

What is the hexadecimal conversion of the decimal number 224?

Anton [14]

Answer:

This is a little confusing to me this question but I think its "E0"

Step-by-step explanation:

a) Divide 224 by 16 and then separate what is on the left and right side of the decimal point.

b) Multiply the right side of the decimal point by 16 (and convert to hex if neccessary) and keep that number to the side.

c) Divide the left side of the decimal point by 16 and separate what is on the left and right side of the decimal point.

d) Repeat step b and c above until the value on the left side is 0.

e) Then simply enter the numbers you got in step b in reverse order to get the answer.

Following the instructions above, your math should look like this:

224 / 16 = 14

0 x 16 = 0

14 / 16 = 0.875

0.875 x 16 = E

Thus, 224 decimal converted to hex is as follows:

E0

The point (6, 6) is on the graph y = f(x) . Find the corresponding coordinates of this point on the graph y = 4f[1/3x +9] -7

miss Akunina [59]

Answer:

Correct answer is:

<em>a. (-9,17)</em>

Step-by-step explanation:

We are given that a point (6, 6) lies on the graph of $y =f(x)$ .

Putting the values from the given point:

$6 =f(6)$

That means we are given that $f(6) =6$ ..... (1)

And we have to find the corresponding coordinates of this point on the graph of $y = 4f[\frac{1}3x +9] -7$

From equation (1), we know the value of $f(6)$ .

so, let us convert $f[\frac{1}3x +9]$ to a form such that it becomes equal to $f(6)$

$\Rightarrow \dfrac{1}{3}x +9 =6\\\Rightarrow \dfrac{1}{3}x=-3\\\Rightarrow x = -9$

So, let us put $x = -9$ in the given function:

$4f[\frac{1}3\times (-9) +9] -7\\\Rightarrow 4f[-3 +9] -7\\\Rightarrow 4f(6) -7$

Now, using equation <em>(1)</em>, putting $f(6)=6$

$\Rightarrow 4\times 6 -7\\\Rightarrow 24-7 \\\Rightarrow y = 17$

Therefore, the point the corresponding point is:

<em>a. (-9,17)</em>
