Answer:

(1/4)w - 1

Step-by-step explanation:

I think you meant, "Subtract (1/4)w + 4 from (1/2)w + 3."

Write (1/2)w + 3 first, with (1/4)w + 4 on the next line; then subtract:

(1/2)w + 3

-[(1/4)w + 4]

-----------------

(1/4)w - 1 (answer)

Find the distance from point A(−1, 7) to the line y=3x. Round your answer to the nearest tenth.

bearhunter [10]

Answer:

The distance from the point to the line is approximately 3.2 units

Step-by-step explanation:

Distance From a Point to a Line

Is the shortest distance from a given point to any point on an infinite straight line. The shortest distance occurs when the segment from the point and the line are perpendiculars.

If the line is given by the equation ax + by + c = 0, where a, b and c are real constants, the distance from the line to a point (x0,y0) is

$\displaystyle d= \frac{|ax_0+by_0+c|}{\sqrt{a^2+b^2}}$

The line is given by the equation:

y=3x. We need to transform it into the specified form.

Subtracting 3x:

y - 3x = 0

Comparing with the general form of the line, we have

a=-3, b=1, c=0

The point (xo,yo) is (-1,7), thus:

$\displaystyle d= \frac{|-3\cdot (-1)+1\cdot 7+0|}{\sqrt{(-3)^2+1^2}}$

$\displaystyle d= \frac{|3+7|}{\sqrt{9+1}}$

$\displaystyle d= \frac{|10|}{\sqrt{10}}$

$\displaystyle d= \frac{10}{\sqrt{10}}$

$d\approx 3.2$

The distance from the point to the line is approximately 3.2 units

MilA has a bag filled with marbles in which situations would the probability of mila drawing a blue marbles from the bag be 1-3

Kamila [148]

Since there were no situation given, I can only provide you with some guidance so you can select the correct answer.

If the probability is 1/3, that means that one out of every three options will need to be blue.

If it is a bag of marbles, you could have 1 blue marble out of a total of 3 marbles. Or any other fraction that reduces to one third.

Here are some examples:

2/6 3/9 4/12 5/15 6/18 7/21 8/24 .....

A. 3 + (-6) B. -3 + (-6) C. 3 + 6 D. -3 + 6

Mashcka [7]

Answer:

D. -3 + 6

Step-by-step explanation:

Starting from zero, we move 3 units to the left. This gives -3.

We now change direction and move to the right 6 units. This gives +6.

Putting the two movements together gives

$- 3 + 6$

The correct choice is D.

Note that moving to the left is considered to be negative while moving to the right is considered positive.
