What is a parallel line to y= -2/3x+3

Natali5045456 [20]

Answer:

-2/3

Step-by-step explanation:

because this is in slope intercept form, m is the slope, so in this case -2/3 is the slope

parallel lines always have the same slope and different y-intercepts

a parallel line could be y=-2/3 +15

which expression represents purely real numbers and which expression represents non-real complex number?

Lyrx [107]

Answer:

Step-by-step explanation:

Complex numbers are the numbers represented by the expression = a + bi

Here a = real part of the number

bi = imaginary part

a and b are the real numbers.

$i^9=(i^2)^4.(i)$

$=(-1)^{4}.i$ [Since, $i^2=-1$ ]

$=i$

Therefore, its a non real complex number.

2 - $\sqrt{-49}$ = $2-\sqrt{(-1)(7)^2}$

= $2-7\sqrt{-1}$

= $2-7i$

This number is a Non real complex number.

$\sqrt{(-18)^2}=18\sqrt{-1}$

= 18i

It's a non real complex number.

3 + 2i

It's a non real complex number.

-289

It's a purely real number.

$4-32i^2=4-32(-1)$

= 4 + 32

= 36

It's a purely real number.
