Answer:

<h3>The answer after performing the indicated operation is in descending powers of x is $5x^2-7x+15$ </h3>

Step-by-step explanation:

Given expression is $(6x^2-4x+11)+(4-x^2-3x)$

<h3>To perform the operation indicated, then place the answer in the proper location on the grid and also Write answer in descending powers of x:</h3>

Now solve the given expression as below ( that is perform the operation indicated)

$(6x^2-4x+11)+(4-x^2-3x)$

$=6x^2-4x+11+4-x^2-3x$

Adding the like terms we get

$=5x^2-7x+15$

$(6x^2-4x+11)+(4-x^2-3x)=5x^2-7x+15$

<h3>The answer after performing the indicated operation is in descending powers of x is $5x^2-7x+15$ </h3>

Solve the two-step equation. -9x + 0.4 = 4 Which operation must be performed to move all the constants to the right side of the

Alexandra [31]

Answer:

x = -0.4

Step-by-step explanation:

We have the equation:

-9x + 0.4 = 4

First, the operation to move all the constants to the right side is subtraction since we would have to subtract 0.4 from each side, let's see this:

$-9x+0.4=4\\-9x+0.4-0.4=4-0.4\\-9x=3.6$

Now, we have all the constants on the right side of the equation.

Now, the operation we need to perform to isolate the variable is division (since the x has a -9 that is being multiplied by x) we need to do the opposite operation:

$-9x=3.6\\\frac{-9x}{-9} =\frac{3.6}{-9} \\x=-0.4$
