Line M with slope 6 is neither, line n with slope -6 is parallel because only lines with same slope are parallel, line p with slope 1/6 is neither. and line q with slope -1/6 is perpendicular because only the reciprocal of a slope is perpendicular, so reciprocal of 6= 1/6 reciprocal of -6=-1/6 reciprocal of 2= 1/2

we have

the slope of the given line is

m1=-6

we know that

If two lines are parallel , then their slopes are the same

so

m1=m2

if two lines are perpendicular, then the product of their slopes is equal to minus one

so

m1*m2=-1

we will proceed to verify each case to determine the solution

<u>case A) </u>line m with slope 6

Compare the slope of the line m of the case A) with the slope of the given line

m1=-6  -----> slope given line

m2=6 ----> slope line m case A)

m1\neq m2

m1*m2\neq-1

therefore

the line m case A) and the given line are neither parallel nor perpendicular

<u>case B) </u>line n with slope -6

Compare the slope of the line n of the case B) with the slope of the given line

m1=-6  -----> slope given line

m2=-6 ----> slope line n case B)

m1=m2 ------> the lines are parallel

<u>case C) </u>line p with slope \frac{1}{6}

Compare the slope of the line p of the case C) with the slope of the given line

m1=-6  -----> slope given line

m2=\frac{1}{6} ----> slope line p case C)

m1*m2=-6*\frac{1}{6}=-1 ------> the lines are perpendicular

<u>case D) </u>line q with slope -\frac{1}{6}

Compare the slope of the line q of the case D) with the slope of the given line

m1=-6  -----> slope given line

m2=-\frac{1}{6} ----> slope line q case D)

m1\neq m2    

m1*m2\neq-1

therefore

the line q case D) and the given line are neither parallel nor perpendicular

The number of members on an organization increases by an average of 125 members annually. There were 3,875 members in 1971. Choo
Lena [83]

Answer:

B.

Mn = Mn-1 + 125 for n > 1 ; M1 = 3,875

Step-by-step explanation:

Since they tell us after 1970, the first data would be that of 1971 and also that if we started since 1970, we do not know the data of 1969, therefore answer B is correct.

Replacing:

Let M1 = 1971 then Mn-1, that is M0 = 1970, we know that the population of 1970 the population is 3750, because it would be 125 less than the subsequent year, and in 1975 there are 3875. Therefore:

in n = 1

 M1 = M0 + 125

3875 = 3750 + 125

this gives an equality, thus fulfilling the equation.
