1 answer:

3 0

If i=imaginary number=√-1 then
√-1 times 237
if you want to simplify as in make it a whole number without the complex part then square the number
(237√-1)^2=(237)^2 times (√-1)^2=56169 times -1=-56169

Write an equation for the line perpendicular to 4x - 12y = 2 and passing through point (10, -1)

MrMuchimi

Answer:

3x+y=-31

Step-by-step explanation:

$4x - 12y = 2\\12y = 4x-2\\y=\frac{x}{3}-\frac{1}{6}$

Slope of perpendicular line is -3.

$y=-3x+b$

Sub in the point (10, -1)

$-1=-3(10)+b\\-1=30+b\\b=-31\\y=-3x-31\\3x+y=-31$

What value of x makes this equation true 12x-15=6-3x

Alex

Answer:

x = 1.4 (or 21/15)

Step-by-step explanation:

12x - 15 = 6 - 3x

+3x +3x

-----------------------

15x - 15 = 6

+15 +15

-----------------------

15x = 21

/15 /15

----------------------

x = 21/15 or

x = 1.4

Which system of inequalities has a solution set that is a line?

Korolek [52]

We're going to solve each of the systems to determine the solution.

System $1$

$x+y \geq 3\\ x+y \leq 3$

using a graph tool

the solution is the line $x+y=3$

see the attached figure N $1$

System $2$

$x+y \geq -3\\ x+y \leq 3$

using a graph tool

the solution is the shaded area

see the attached figure N $2$

System $3$

$x+y > 3\\ x+y < 3$

using a graph tool

The system has no solution

see the attached figure N $3$

System $4$

$x+y > -3\\ x+y < 3$

using a graph tool

the solution is the shaded area

see the attached figure N $4$

therefore

the answer is

System $1$ 

$x+y \geq 3\\ x+y \leq 3$
