The coordinates of the point N after the transformation is (-7,-4)

Explanation:

Given that the coordinates of the point N is (7,4)

The point is rotated 180° counterclockwise about the origin.

We need to determine the coordinates of the point N after the rotation 180° counterclockwise about the origin.

Coordinates of the image:

The transformation rule to rotate the point 180° counterclockwise about the origin is given by

$(x, y) \rightarrow(-x,-y)$

Substituting the point (7,4), we get,

$(7,4)\implies(-7,-4)$

Thus, the coordinates of the point N after the transformation is (-7,-4)

How to solve 4/7y-2 = 3/7 + 3/14

lisabon 2012 [21]

Solution

1) Simplify $\frac{4}{7y}$ to $\frac{4y}{7}$
$\frac{4y}{7}$ −2= $\frac{3}{7}$ + $\frac{3}{14}$

2) Simplify $\frac{3}{7}$ + $\frac{3}{14}$ to 914
 $\frac{4y}{7}$ −2= $\frac{9}{14}$

3) Add 2 to both sides
 $\frac{4y}{7}$ = $\frac{9}{14}$ +2

4) Simplify $\frac{9}{14
}$ +2 to $\frac{37}{14}$
$\frac{4y}{7}$ = $\frac{37}{14}$

5) Multiply both sides by 7
4y= $\frac{37}{14}$ ×7

6) Simplify $\frac{37}{14}$ ×7 to $\frac{259}{14}$
$\frac{4y}{7}$ = $\frac{259}{14}$

7) Simplify $\frac{259}{14}$ to $\frac{37}{2}$
$\frac{4y}{7}$ = $\frac{37}{2}$

8) Divide both sides by 4
y= $\frac{37}{2}$ ×4

9) Simplify 2×4 to 8
y= $\frac{37}{8}$

Hope this helps

Given that every week, Bob plays the guitar for three hours, and his grade on each psych test is 75 percent.

Last week, after playing for three hours, Bob considered playing for an additional hour.

He decided to play for another hour and cut his study time by one hour, but last week his psych grade was 55 percent.

Bob's opportunity cost of the fourth hour of playing the guitar
