elixir [45]

Answer:

Part 41) The solutions are 3 and 1

Part 42) The solution is 2 only

Step-by-step explanation:

Part 41) we have

$\left|5x-9\right|=x+3$

step 1

Find the first solution (case positive)

$+(5x-9)=x+3$

$5x-x=3+9$

$4x=12$

$x=3$

step 2

Find the second solution (case negative)

$-(5x-9)=x+3$

$-5x+9=x+3$

$5x+x=9-3$

$6x=6$

$x=1$

therefore

The negative case was resolved incorrectly

The solutions are 3 and 1

Part 42) we have

$\left|n-7\right|=3n-1$

step 1

Find the first solution (case positive)

$+(n-7)=3n-1$

$3n-n=-7+1$

$2n=-6$

$n=-3$

<em>Verify</em>

For n=-3

substitute

$\left|-3-7\right|=3(-3)-1$

$\left|-10\right|=-9-1$

$10=-10$ ------> is not true

therefore

$n=-3$ -------> is not a solution

step 2

Find the second solution (case negative)

$-(n-7)=3n-1$

$-n+7=3n-1$

$3n+n=7+1$

$4n=8$

$n=2$

therefore

The solution is 2

Directions: for questions 1 through 4, find the diagonal length of each solid figure.

Alex787 [66]

$\text{The length of the diagonal is }11.2\text{ mm}$

Here, we want to find the diagonal of the given solid

To do this, we need the appropriate triangle

Firstly, we need the diagonal of the base

To get this, we use Pythagoras' theorem for the base

The other measures are 6 mm and 8 mm

According ro Pythagoras' ; the square of the hypotenuse equals the sum of the squares of the two other sides

Let us have the diagonal as l

Mathematically;

$\begin{gathered} l^2=6^2+8^2 \\ l^2\text{ = 36 + 64} \\ l^2\text{ =100} \\ l\text{ = }\sqrt[]{100} \\ l\text{ = 10 mm} \end{gathered}$

Now, to get the diagonal, we use the triangle with height 5 mm and the base being the hypotenuse we calculated above

Thus, we calculate this using the Pytthagoras' theorem as follows;

$\begin{gathered} d^2=5^2+10^2 \\ d^2\text{ = 25 + 100} \\ d^2\text{ = 125} \\ d\text{ = }\sqrt[]{125} \\ d\text{ = }11.2\text{ mm} \end{gathered}$
