Answer: x^2 + 3x - 1.

Step-by-step explanation: We need to divide x^3 + 5x^2 +5x-2 by x+2. This is dividing polynomials. Divide each number by x and multiply the quotient by 2 and subtract the answer.

Get the equation of the line containing PQ using the point-slope formula:

<em>y</em> - (-2) = 3/2 (<em>x</em> - (-6))

Solve for <em>y</em> to get it in slope-intercept form:

<em>y</em> = 3/2 <em>x</em> + 7

so the <em>y</em>-intercept is (0, 7).

The line containing QR is then

<em>y</em> - 7 = -3/4 (<em>x</em> - 0)

or

<em>y</em> = -3/4 <em>x</em> + 7

The point R is on the <em>x</em>-axis, so its <em>y</em>-coordinate is 0. Plug in <em>y</em> = 0 and solve for <em>x</em> to get the other coordinate:

0 = -3/4 <em>x</em> + 7

3/4 <em>x</em> = 7

<em>x</em> = 4/3×7 = 28/3

So the point R has coordinates (28/3, 0).

What property is illustrated by 6*1=6?
KatRina [158]
For this case we have the following expression:
 6 * 1 = 6
 We observe that we have two numbers that multiplied give as a result the value of one of the numbers.
 The name of this property is called identity property.
 In matrices there is also the identity matrix. It is a matrix whose diagonal is formed by the number one.
 Answer:
 
A property that is illustrated by 6 * 1 = 6 is:
 
identity
