Could two lines with negative slope be perpendicular? Explain.

1 answer:

3 0

No. For two lines to be perpendicular their slope must be the negative reciprocals of one another, mathematically:

m1*m2=-1

So if the slope of one line is negative, the line perpendicular to this must be positive by definition.

REY [17]

Answer:

A total of 720 elk are likely to be infected

Step-by-step explanation:

we shall be using the proportion by survey to estimate the number of infections

From the survey 8 out of 50 are infected. Thus the likelihood of infection is 8/50

We have 4,500 elk to consider. The number of elk likely to be infected will be 8/50 * 4500 = 720

A company can manufacture x hundred items for a total cost of C=300+1200x-100x. Find x if the total cost is 3,000

Scilla [17]

C=300+1200x-100x. Find x if the total cost is 3,000
3,000 = 300 + 1200x -100x
3000 = 300 + 1100x
2700 = 1100x
2700÷1100=x
x=27/11
x = 2 5/11 Round to 3
