Which is a solution of the inequality 5≤−4x−65≤−4x−6?

1 answer:

4 0

Step 1: Add 65 to all sides

Step 2: Add 4x to all sides

Step 3: subtract 70 to all sides

Step 4: divide by 4 to all sides

Ending: x is greater than or equal to -17.5

You will end up with it saying -17.5 is greater than or equal to -2.75 but since -17.5 is not greater than -2.75 the answer to this problem is ...

No solution because the inequality that you end up with won't make sense and therefore does not work in the problem

Answer: NO SOLUTION (yayayyayay).

Which inequality is represented by the accompanying graph?<br> Thank you!!!

yan [13]

Answer:

y<3

Step-by-step explanation:

It is y<3 because all areas below y=3 are shaded.

In addition, the line y=3 is dotted, which means it is not part of the inequality (i.e. strict inequality).

If it had been a full line, then it would be y<=3.

Three houses A B and Clie on the same line on a map. House Blies exactly in the middle of house A and house C The point (3,6) on

Svetlanka [38]

Answer:

(-13, -12)

Step-by-step explanation:

The midpoint (x,y) between two points ( $x_1,y_1$ ) and ( $x_2,y_2$ ) on the coordinate plane is given by:

$x=\frac{x_1+x_2}{2};\\\\y=\frac{y_1+y_2}{2}$

Hence given that house A is at (3, 6) and house B is at (-5, -3). Since house B is placed at the middle of house A and house B, let the coordinates of house C be ( $x_2,y_2$ ). Hence:

$-5=\frac{3+x_2}{2\\} \\3+x_2=-10\\\\x_2=-10-3\\\\x_2=-13$

$-3=\frac{6+y_2}{2\\} \\6+y_2=-6\\\\y_2=-6-6\\\\y_2=-12$

Therefore house C is at (-13, -12)
