Consider the following system of two linear equations:
harkovskaia [24]

Hello,

Answer:

The last graph (2;3)

Step-by-step explanation:

2x + 3y = 12

2x – 3y = 0

2x + 3y = 12

2x = 3y

3y + 3y = 12 ⇔ 6y = 12 ⇔ y = 12/6 = 2

2x + 3 × 2 = 12 ⇔ 2x + 6 = 12 ⇔ 2x = 6 ⇔ x = 6/2 = 3

Given two dice, what is the probability of rolling a four on the second die, given that you already rolled a four on the first d
Sholpan [36]

Answer:   1/6

Reason:

There's 1 side labeled "4" out of 6 sides total. So that's where the 1/6 comes from.

The "given that you already rolled a four on the first die" is unneeded info in my opinion, because each die is separate or independent from one another.

A group of hikers walks 3 miles east and then 1 mile north. After taking a break, they then hike 4 miles east to their final des
geniusboy [140]

Answer:

The vector that describes their hike from their starting position to their final destination is \vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi].

Step-by-step explanation:

In this problem we assume that orthogonal axes coincide with the north and east. We proceed to translate each sentence from statement into vectorial equations:

(i) <em>A group of hikers walks 3 miles east and then 1 mile north:</em>

\vec r_{A} = 3\,\hat{i}+1\,\hat{j}\,\,\,[mi]

(ii) <em>After taking a break, they then hike 4 miles east to their final destination:</em>

\vec r_{B} = 4\,\hat{i}\,\,\,[mi]

The vector that describes their hike from their starting position to their final destination is the sum of the vectors deducted above. That is:

\vec r = \vec r_{A}+\vec r_{B}  (1)

\vec r = (3\,\hat{i}+1\,\hat{j})+4\,\hat{i}\,\,\,[mi]

\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi]

The vector that describes their hike from their starting position to their final destination is \vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi].
