Lelu [443]

We are given coordinates of the school located at a point (9,-1).

Library is located 5 blocks south and 4 blocks west .

According to coordinate axes, south is downward and west is on left side.

So, we need to move 5 units down of 9.

<em>5 units down of 9 would be 9-5 = 4.</em>

And then <em>4 blocks west that mean -1 -4 = -5.</em>

<h3>Therefore, coordinate of the library is located at the point (4,-5).</h3>

Solve for x: 3(x + 1) = −2(x − 1) − 4<br><br> 1<br><br> −1<br><br> −5<br><br> −25
LekaFEV [45]

Answer:

x = - 1

Step-by-step explanation:

3(x + 1) = - 2(x - 1) - 4 ←  distribute parenthesis on both sides

3x + 3 = - 2x + 2 - 4

3x + 3 = - 2x - 2 ( add 2x to both sides )

5x + 3 = - 2 ( subtract 3 from both sides )

5x = - 5 ( divide both sides by 5 )

x = - 1
