Answer:

b. 3/1 c. -1/3

Step-by-step explanation:

When a line is parallel to another they don't intersect and instead go in the same direction. Therefore they have the same slope

b. 3/1

When a line is perpendicular it has to be the negative reciprocal. This means that it you have to flip the numbers in the fraction and make it negative (unless it is already negative, then it becomes positive)

c. -1/3

How to solve this problem

Eddi Din [679]

Answer:

Solving the radical $\pm\sqrt{-81}$ we get $\mathbf{\pm9 \ i}$

Step-by-step explanation:

We need to express the radical $\pm\sqrt{-81}$ using the imaginary unit i

Prime factors of 81 are: 3x3x3x3

and $\sqrt{-1}=i$

Solving:

$\pm\sqrt{-81}\\=\pm\sqrt{81}\sqrt{-1}\\=\pm\sqrt{3\times3\times3\times3}i\\ =\pm\sqrt{3^2\times3^2}i\\=\pm3\times3\ i\\=\pm9 \ i$

So, Solving the radical $\pm\sqrt{-81}$ we get $\mathbf{\pm9 \ i}$

Imani=i
Miguel=m

i=2m+3
i+m=87
i=-m+87
2i=m+90
i=(m+90)/2
2m+3=(m+90)/2
2m+3=m/2+45
4m+6=m+90
3m+6=90
3m=84
m=28

Hope this helps :)

Can someone please help me solve for x? i already have y

Scrat [10]

Step-by-step explanation:

$\frac{3}{9} = \frac{5}{y} = \frac{x}{12} \\ \frac{3}{9} = \frac{5}{y} \\ 3y = 45 \\ y = 15 \\ \\ \frac{3}{9} = \frac{x}{12} \\ 9x = 36 \\ x = 4$
