Write a equation of a line that is perpendicular to y = -2/7x+9and pass through point (4,-6)

nikitadnepr [17]

Answer:

y = 7/2x - 20.

Step-by-step explanation:

The slope of the given line is -2/7, therefore the slope of the line perpendicular to it is - 1/ -2/7 = 7/2.

When x = -4, y = -6 so we substitute x1 = 4, y1 = -6 and m ( the slope) = 7/2 in the point slope form of a line:

y - y1 = m(x - x1)

y - (-6) = 7/2(x - 4)

y + 6 = 7/2x - 14

y = 7/2x - 20.

Write a word problem with 1/2 as the dividend and 3 as the divisor. then find the quotient

lisabon 2012 [21]

Answer:

The word problem is described.

Each child will get $\frac{1}{6}\text{ kg}$ of wheat.

Step-by-step explanation:

Word Problem:

A woman have 0.5 kg of wheat. She need to distribute it equally among her three children. How much amount of wheat will each child get?

Solution:

Total weight of wheat =

$0.5\text{ kg} = \dfrac{1}{2}\text{ kg}$

Number of children = 3

Amount of wheat each child will get =

$=\dfrac{\text{Total amount of wheat}}{\text{Number of children}}\\\\=\dfrac{\frac{1}{2}}{3}\\\\(\text{Divident} = \dfrac{1}{2},\text{ Divisor} = 3)\\\\=\dfrac{1}{6}\text{ kg}\\\\=0.167\text{ kg}$

Thus, each child will get $\frac{1}{6}\text{ kg}$ of wheat.
