Okay, I would multiply 4 times 12 since there is 12 inches in a foot and then divide it by 3.  which the answer would be 16 inches.

4 feet
each friend gets 1/3 foot
if you wante to do \frac{4}{ \frac{1}{3} }
try to make bottom number=1
1/3 times 3/1=3/3=1
multiply the whole thing by \frac{ \frac{3}{1} }{ \frac{3}{1} }

\frac{4*3}{ \frac{3}{3} }
\frac{12}{ 1}

Consider the line y = - 4x +8.
Damm [24]

Answer:

The equation for the parallel line is: y = -4x - 20

The equation for the perpendicular line is: y = 1/4x + 11/2

Step-by-step explanation:

The given point is: (-6, 4)

The given equation is:

y = -4x + 8, note the slope m = -4.

A parallel line has the same slope. Use the point slope and substitute:

y - y1 = m(x - x1)

y - 4 = -4(x - (-6))

y - 4 = -4(x + 6)

y - 4 = -4x - 24

y = -4x - 20

Proof - find f(x) when x = -6:

f(x) = -4x - 20

f(-6) = -4(-6) - 20

f(-6) = 24 - 20 = 4, so the point is (-6, 4)

A perpendicular line has a slope that is negative and inverted so m = 1/4.

y - y1 = m(x - x1)

y - 4 = 1/4(x - (-6))

y - 4 = 1/4(x + 6)

y - 4 = 1/4x + 6/4

y - 4 = 1/4x + 3/2

y = 1/4x + 3/2 + 4

y = 1/4x + 3/2 + 8/2

y = 1/4x + 11/2

Proof - find f(x) when x = -6:

f(x) = 1/4x + 11/2

f(-6) = 1/4(-6) + 11/2

= -6/4 + 11/2

= -3/2 + 11/2

= 8/2 = 4, giving the point (-6, 4)

Factor −6 out of −18a−30
fgiga [73]

Remark

This is like using the distributive principle only you are going backwards. Instead of trying to remove brackets, you are trying to create them.

Solution

Since you want to take - 6 outside the brackets you should divide both terms by - 6

<em><u>- 18a</u></em>: - 18a/- 6 = 3a  which is left inside the brackets.

<em><u>-30:</u></em> - 30/-6 = 5

- 6(3a + 5)

Answer

-6(3a + 5)
