SCORPION-xisa [38]3 years ago
7 0

Step-by-step explanation:

We need to find thr range if

\frac{1}{ (|x|  - x)}

The absoulte value of something is positive.

So

\frac{1}{x - x}  =  \frac{1}{0}

This function isn't possible so no range exist.

Change the subject of the equation v = u + at to a.
emmasim [6.3K]
<h3>Answer ↓</h3>

<h3>Calculations ↓</h3>

In order to make a the subject of this equation , we need to get a by itself .

The current equation is :

v = u + at

Subtract u on both sides :

v-u=at

Now, divide by t on both sides :

v-u/t=a

<h3>So the formula looks like ↓</h3>

\boxed{\\\begin{minipage}{3cm}Equation \\ a=$\displaystyle\frac{v-u}{t} $ \\ \end{minipage}}

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

24.

<u>Statement</u>                    <u>Reason</u>

1. BD = CA                    1. Given

2. AB = CD                  2. Given

3. AD = AD                  3. Reflexive Property

4. ΔABD = ΔDCA        4. SSS Congruency Theorem

<em>We have no information about the angles so cannot use SAS Theorem.</em>

26.  G H F

      E H D

Line up the letters to find the congruent sides:

⇒  GH = EH

    HF = HD

Juliette [100K]

Answer:

9 days.

hope it helps

Step-by-step explanation:

As per given data

1/x=1/(x+27)+1/(x+3)

1/x=(x+3+x+27)/(x+27)(x+3)

X^2+30x+81=2x^2+30x

X^2=81

X=9

so A&B can together do the work in 9 days
