Answer:

Step-by-step explanation:

Rotate counter-clockwise = from right towards left  

Rotate 90° about the origin = We can think that our rectangle is a flag and that we added a pole to it. The pole is rotated counter-clockwise about the origin until we have the 90°. Where is the flag now positioned?

(Draw a line from origin to one of the rectangle's points; draw another line from origin that is ⊥ to the previous one. You rotate that point 90° from right to left and will lend on the new line.)

1. K (-6, 3) L (-4, 5) M (-1, 2) N (-3, 0) → K' (-3,-6) L'(-5, -4) M'(-2, -1) N'(0, -3)

2. We notice that the rule for rotating 90° about the origin is (x, y)→(-y, x)

Answer:

See below ↓

Step-by-step explanation:

1)

  • On rotating KLMN by 90° counterclockwise,
  • the new coordinates are :
  • K' = (-3, -6)
  • L' = (-5, -4)
  • M' = (-2, -1)
  • N' = (0, -3)

2)

  • What do we notice here?
  • We notice that on rotating from Quadrant II to Quadrant III, we find that all the x and y values become negative (other than N' which changes intercepts from x to y)

Simply add the binomials together.

(3x - 2) + (2x +  1)

Combine like terms.

What is the first step in solving the following equation?<br> 28 = -12 - 4x
alexgriva [62]

Answer:

<h3>4x = - 12 - 28</h3>

Step-by-step explanation:

When we transpose - 4x to the LHS then it becomes positive i.e +4x

Now we transpose 28 to the RHS then it becomes negative i.e - 28

So the first step you have to is,

<em>4x = - 12 - 28</em>

Target sells 24 bottles of water for $3, and 36 bottles of water for $4. Which is the better buy and by how much?
pishuonlain [190]

Answer:

D) 36 bottles for $4 by 1.4¢ per bottle

Step-by-step explanation:

We calculate bottle per dollar for each option.

#A

Bottles/Dollar=\frac{24\ bottles}{\$3}=8 bottles/dollar

#Both B and C charges the same as A and will have bottle/dollar ration of 8:1

#D

=\frac{36}{4}\\\\=9

Hence, D is the better buy  as it gives you 9bottles per $1 spent as compared to the 8 bottles per $1 spent as in the other 3 options.

dem82 [27]

Chord AB is the diameter of circle O.

Step-by-step explanation:

The law of detachment states that if the following two statements are true;

(i) if p then q

(ii)p

Then the third true statement is;

(iii)q

In this case;

Let

(i) If a chord extends through the center of a circle---- p

 (ii)It is the diameter of the circle-----q

Then (i) and (ii) can be written as;

(i) If p then q

(ii) p

Here q is true, Chord AB is the diameter of circle O.
