AysviL [449]3 years ago
3 0

Answer:

<h2>y = 9</h2>

Step-by-step explanation:

Put x = 5 to the equation -6x - 3y = -57

(-6)(5) - 3y = -57

-30 - 3y = -57            <em>add 30 to both sides</em>

-3y = -27           <em>divide both sides by (-3)</em>

y = 9

Sholpan [36]

Answer:

12 times 5=60 not 70

Step-by-step explanation:

12(5+2y)=4y-(5-9y

60+24y=4y-5-9y

60+24y=-5y-5

29y+60=-5

29y=-65

y=-65/29 or y= about -2.38

Find all the roots of the equation x4 - 2x3 + 14x2 - 18x + 45 = 0 given that 1 + 2i is one of its roots.
patriot [66]
Asked and answered elsewhere.
brainly.com/question/10192511


Knowing that 1+2i is a root, you also know that 1-2i is a root, so one quadratic factor is
   (x -1)² -(2i)² = x^2 -2x +5

Long division of the given polynomial by this quadratic gives a quotient of 
  x² +9
which has roots ±3i.

Then all the roots are {-3i, 3i, 1-2i, 1+2i}.
