\dfrac{4}{5}n-\dfrac{3}{5}=\dfrac{1}{5}n\ \ \ \ \ |multiply\ both\ sides\ by\ 5\\\\4n-3=n\ \ \ \ |add\ 3\ to\ both\ sides\\\\4n=n+3\ \ \ \ |subtract\ n\ from\ both\ sides\\\\3n=3\ \ \ \ |divide\ both\ sides\ by\ 3\\\\\boxed{n=1}

Answer:

The correct result would be n = 1.

Step-by-step explanation:

4/5n - 3/5 = 1/5n     /*5n

4 - 3/5 * 5n = 1

4 - 3n = 1

4 - 1 = 3n

3 = 3n

n = 1

Find the inequality represented by the graph.
iris [78.8K]

Answer:

<h2>x \geqslant  \frac{y + 4}{3}</h2>

Explanation;

Associated line with this equation is:

y=mx+c

when,

X=0

y=-4

so, c=-4

X=1

y=-1

- 1 = m- 4 \\  - m =  - 4 + 1 \\  - m =  - 3 \\ m =3 \\

y = 3x - 4 \\ or \: y + 4 = 3x \\ or \:  \frac{y + 4}{3}  = x

Inequality representated by graph:

x \geqslant  \frac{y + 4}{3}

Hope this helps...

Good luck on your assignment...
