The answer would be multiplicative by -2 because every x value can be multiplied by -2 to get the y value

-8z+(4.5)+3.5z+7y-1.5

bogdanovich [222]

Answer:

$\boxed{\sf{7y+3-4.5z}}$

Step-by-step explanation:

In order to combine like terms, you have to isolate x and y from one side of the equation.

$\sf{-8z+\left(4.5\right)+3.5z+7y-1.5}$

<u>First, thing you do is remove parentheses.</u>

$\Longrightarrow: \sf{-8z+4.5+3.5z+7y-1.5}$

<u>Solve.</u>

<u>Then, you combine like terms.</u>

$\Longrightarrow:\sf{-8z+3.5z+7y+4.5-1.5}$

<u>Add/subtract the numbers from left to right.</u>

-8z+3.5z=-4.5z

<u>Rewrite the problem down.</u>

$\Longrightarrow: \sf{-4.5z+7y+4.5-1.5}$

<u>Solve.</u>

4.5-1.5=3

$\Longrightarrow: \boxed{\sf{7y+3-4.5z}}$

<u>Therefore, the correct answer is 7y+3-4.5z.</u>

I hope this helps, let me know if you have any questions.

Find all the roots of the equation x4 - 2x3 + 14x2 - 18x + 45 = 0 given that 1 + 2i is one of its roots.

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}.
