What is the greatest common factor (gcf) of the numerator and denominator in the rational expression below? 7x+14/2x^2+x-6

1 answer:

4 0

The answer is C. The numerator 7x+14 can be factored as 7(x+2). The denominator 2x^2+2x-6 can be factored as (x+2)(2x-3). The greatest common divisor of 7(x+2) and (x+2)(2x-3) is obviously x+2, which is contained in both of the two expressions.

Write an absolute value inequality that describes the acceptable weights, w, of a 20-ounce bottle of sports drink.

Shtirlitz [24]

Answer: $0\leq w\leq 20$

Step-by-step explanation:

Since, Here w represents the weight of the bottle.

And, According to the question, he acceptable weights, w, of a 20-ounce bottle of sports drink.

That is, weight of the bottle can not be higher than 20 or the it can be atleast 20.

Therefore, $w\leq 20$

And, the weight can not be negative.

Therefore, $0\leq w$

Thus, the required inequality is,

$0\leq w\leq 20$

Find the equation of the line<br> That is perpendicular to y=-2x+1 and contains the point (8,2)

skelet666 [1.2K]

Answer:

y=.5x-2

Step-by-step explanation:

If one line is perpendicular to another that means that their slopes are negative reciprocals

which means that the slope (or m in y=mx+b) is .5

so far we have

y=.5x+b

to solve for b we plug in (8,2)

2=.5(8)+b

2=4+b

-2=b

therefore our equation is

y=.5x-2
