Answer:

First Step: separate x^2 from -16

Second Step: add -16/25 to the other side.

Step-by-step explanation:

x^2 - 16/25 = 0

^^ this might be easier if you separate x^2 and -16

First Step-

so rewrite the problem as x^2/25 -16/25 = 0

then...

Second Step-

add -16/25 to the other side. This makes it: x^2/25 = 16/25

Continuation-

Now, you can multiply 25 on both sides to cancel it out.

so you have x^2 = -16

Message me if you want to solve for x.

Step-by-step explanation:

$\sqrt[6]{5} \times \sqrt[2]{5}$

$= {5}^{ \frac{1}{6} } \times {5}^{ \frac{1}{2} }$

$= {5}^{ \frac{1}{6} + \frac{1}{2} }$

$= {5}^{ \frac{1 + 3}{6} }$

$= {5}^{ \frac{4}{6} }$

$= {5}^{ \frac{2}{3} }$

$= \sqrt[3]{ {5}^{2} } (ans)$

Two nonvertical lines have slopes m 1 and m 2, respectively. The lines are parallel if _______ and the _______ are unequal;

kondor19780726 [428]

we know that

If two lines are parallel, then their slopes are the same

m1=m2

and the y-intercept is unequal

If two lines are perpendicular, then the product of their slopes is equal to -1

m1*m2=-1 or m1=-1/m2

therefore

the answer is

Two non vertical lines have slopes m1 and m2, respectively. The lines are parallel if m1=m2 and the y-intercept are unequal; the lines are perpendicular if m1*m2=-1 or m1=-1/m2.
