(x,y) -->(-x, -y) ....180 rotation either clockwise or counterclockwise

then from (x,y) _> (x, -y) ....reflect over x axis

Answer is the third option

ABC is congruent to A'B'C' because rules represent a rotation followed by a reflection which is a sequence of rigid motions

HELP!! PLEASE A carpenter is framing a window with wood trim where the length of the window is 9 and 1/3 feet. If the width of t

ohaa [14]

We need the perimeter of the window for framing

The window is in the shape of a rectangle with the height of $9 \frac{1}{3}$ feet and width of $6 \frac{3}{4}$ . The diagram of the shape is shown below

The perimeter of a shape is obtained by adding up the length of all the sides that form the shape.

The perimeter of the window is $9 \frac{1}{3}+9 \frac{1}{3}+6 \frac{3}{4}+6 \frac{3}{4}$ = $18 \frac{2}{3}+12 \frac{6}{4}$

We have two whole numbers 18 and 12 and two fractions $\frac{2}{3}$ and $\frac{6}{4}$

Adding the two fractions that have different denominator
$\frac{2}{3}+ \frac{6}{4} = \frac{8}{12}+ \frac{18}{12}= \frac{26}{12}$ , which is an improper fraction which we can change into a mixed number $2 \frac{1}{6}$

So the perimeter of the window is
$18+12+2 \frac{1}{6} =32 \frac{1}{6}$

and the length of wood needed for the frame is $32 \frac{1}{6}$ feet

two years ago the cats tim and tom were toghether 15 years old.Now tom is 13 years old.In how many years will tim be 9 years old

Norma-Jean [14]

Answer:

3 years

Step-by-step explanation:

As with many age problems, you can reason it without equations. If Tom is 13 now, 2 years ago he was 11. If the total age of the two cats at that time was 15, then Tim was 15 -11 = 4.

That means Tim is now 4+2 = 6, so will be 9 in 3 years.

Additional comment

If you want to write equations, there are several ways you can do it. We often like to use variables to represent the current age. We can assign ...

x = Tim's current age; y = Tom's current age.

The sum of their ages 2 years ago was ...

(x -2) +(y -2) = 15

Tom's current age is 13, so we have y=13. Using that in the equation gives ...

x -2 +13 -2 = 15

x = 6 . . . . . . . . . . subtract 9, collect terms

That's Tim's current age, so Tim will be 9 years old in 3 years.
