9514 1404 393

Answer:

  C. Division: (x^2-5x+3)÷(x-2)=x-3+-3/x-2

Step-by-step explanation:

The set of polynomials is closed under all basic arithmetic operations except division. The reciprocal of a (non-constant) polynomial is not a polynomial.

The division example shown in choice C illustrates the set is not closed under division.

AB contains points (2, 1) and (-1, -8). What is the equation of the line parallel to AB that contains point (0, 2)?
Iteru [2.4K]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have two points that belong to the AB line:

(x_ {1}, y_ {1}) :( 2,1)\\(x_ {2}, y_ {2}): (- 1, -8)

We can find the slope:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-8-1} {- 1-2} = \frac {-9} {- 3} = 3

By definition, if two lines are parallel then their slopes are equal. Thus, a line parallel to AB will have slope m = 3, then the equation will be of the form:

y = 3x + b

We substitute the given point and find b:

(x, y) :( 0,2)\\2 = 3 (0) + b\\2 = b

Finally, the equation is:

y = 3x + 2

Answer:

y = 3x + 2

If AABC ~ AEDC, find the value of x.<br> a. 32<br> 5.8<br> C. 40<br> d. 15
alukav5142 [94]

Answer:

x = 15

Step-by-step explanation:

If ABC similar to EDC then we can use the similarity ratio to find the value of x

32/(3x-5) = 56/(5x-5) cross multiply the fractions

160x - 160 = 168x - 280 export like terms to the same side of the equation

280 - 160 = 168x - 160x

120 = 8x divide both sides by 8

15 = x
