Subtract -6x^4-3x^2y^2+5y^4−6x

Gnoma [55]

Answer:

$8x^4-5x^2y^2-6y^4+6x$

Step-by-step explanation:

We are required to subtract $-6x^4-3x^2y^2+5y^4-6x \:from \: 2x^4-8x^2y^2-y^4$ .

$[2x^4-8x^2y^2-y^4]-[-6x^4-3x^2y^2+5y^4-6x]$

Step 1: Open the bracket, Take note of the signs

$[2x^4-8x^2y^2-y^4]-[-6x^4-3x^2y^2+5y^4-6x]\\2x^4-8x^2y^2-y^4+6x^4+3x^2y^2-5y^4+6x$

Step 2: Collect like terms

$2x^4+6x^4-8x^2y^2+3x^2y^2-y^4-5y^4+6x$

Step 3: Simplify

$8x^4-5x^2y^2-6y^4+6x$

Emily designed a robot that could climb down steps. She drew a graph to show the results from a test of her new robot. The graph

Artist 52 [7]

The generic equation of the line is:

$y = mx + b$

Where,

m: slope of the line.

b: cutting point with vertical axis.

The slope of the line is given by:

$m =\frac{y2-y1}{x2-x1}$

$m =\frac{14-15}{10-0}$

$m =-\frac{1}{10}$

The cutting point with the vertical axis is:

$b=15$

Therefore, the equation of the line is:

$y =-\frac{1}{10}x + 15$

Answer:

the equation that represents Emily’s situation is:

$y =-\frac{1}{10}x + 15$
