Answer:

If the slopes of the lines are both zero, the lines are horizontal and are parallel by definition. Since the slopes of vertical lines are undefined and not considered equal, vertical lines will not be considered.

I hope this helps you :)

What are the coordinates of the point in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the r

boyakko [2]

Answer:

The coordinates of the point X:

(x, y) = (-1, -7)

Step-by-step explanation:

Let X be the point.

As the point X is in the directed line segment from (-2,-8) to (5,-1) into the ratio of 1 to 6

i.e.

$\left(x_1,\:y_1\right)\:=\:\left(-2,-8\right)$

$\left(x_2,\:y_2\right)=\left(5,-1\right)$

Rise = y₂ - y₁

$= -1 - (-8)$

$= -1 + 8$

$= 7$

Run = x₂ - x₁

$= 5 - (-2)$

$= 5 + 2$

$= 7$

1 : 6 ratio means the point X lies at

$\frac{1}{6+1}=\frac{1}{7}=14\%$

Thus,

rise for X $=\:7\:\times \:14\%=1$

run for X $=\:7\:\times \:14\%=1$

Thus, coordinates of X will be:

$x = -2 + 1 = -1$

$y = -8 + 1 = -7$

Therefore, we conclude that:

The coordinates of the point X:

(x, y) = (-1, -7)

Solve -5(3n + 4) = 40. <br> -4<br> -3<br> 3<br> 4

Nuetrik [128]

Our current equation is:
-5(3n + 4) = 40

To solve for this, we need to use the Distributive Property. The Distributive Property allows any number/variable outside of the parenthesis to be multiplied by all numbers/variables inside of the parenthesis.

For example, 3(2 + 3) would be:
3(2) + 3(3)
6 + 9
15.

Now that we've defined our terms and provided an example, I think we're ready to solve.

-5(3n + 4) = 40
-5(3n) + -5(4) (multiplying a positive by a negative makes a negative)
-15n -20 = 40
Add 20 to both sides to get -15n by itself.
-20 + 20 = 0
40 + 20 = 60

We now have:
-15n = 60

Divide both sides by -15 to solve for n.
-15n / -15 = n
60 / -15 = -4

N = -4.

Your answer is A.) -4.

I hope this helps!
