Answer:

y=13+3x

Step-by-step explanation:

If this is the only equation given, you would want to isolate the y by itself.

y - 3x = 13

+3x +3x

Add the 3x because you are doing the opposite operation.

y=13+3x

It took my question down twice here's a real math question I guess

aliina [53]

Answer:

$n-3$

Interval notation: $(-\infty, -10)\cup(-3,\infty)$

Step-by-step explanation:

First inequality:

$n+8$

Therefore, this inequality restricts:

$n \in \mathrm{R};\: n$

Second inequality:

$< 8+n-3$

Therefore, this inequality restricts:

$n \in \mathrm{R};\: n>-3$

Therefore, with both of these restrictions together, we have:

$\fbox{$n \in \mathrm{R}; n-3$}\\\mathrm{or\:}\fbox{$n-3$}\\\mathrm{or\:}\fbox{$(-\infty, -10)\cup(-3,\infty)$}$ .

PLEASE HELP What is the radical form of the expression 423 ? 43−−√ 34−−√ 42−−√3 24−−√3

ira [324]

For this case we must express the number "423" in a radical way.

We have to, we can rewrite it as:

$423 = 9 * 47 = 3 ^ 2 * 47$

So, we have to:

$423 = \sqrt {3 ^ 2 * 47}$

By definition of properties of powers and roots we have:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

So:

$423 = \sqrt {3 ^ 2 * 47} = 3 \sqrt {47}$

Answer:

$3 \sqrt {47}$
