1. First transformation is rotation rotation of 180 about the origin. This transformation has a rule:

(x,y)→(-x,-y).

If points E(-2,-4), F(-1,-1), D(-2,-1) are vertices of triangle EFD, then

E(-2,-4)→E''(2,4),
F(-1,-1)→F''(1,1),
D(-2,-1)→D''(2,1).

2. Second transformation is translation 1 unit left with a rule

(x,y)→(x-1,y).

Then

E''(2,4)→E'(1,4),
F''(1,1)→F'(0,1),
D''(2,1)→D'(1,1).

Answer: 1st: rotation of 180 about the origin; 2nd: translation 1 unit left.

Answer:

a) $\frac{32}{21}$

b) -14

c) -3

d) -96

Step-by-step explanation:

a) The parenthesis indicate multiplication.

b) Minus and plus gives subtraction, and the sign you put behind the number is the sign of the largest number you have (in this case it's 21 since we ignore the -)

c) They already have common denominators, all that's left is to do $\frac{-7 -2}{3} = \frac{-9}{3} = -3$

d) The parenthesis indicate multiplication.

Good luck!

The first step is to define the system of equations.

Take x and y as the cost of a small box and a large box respectively.

$\begin{gathered} 2x+y=12 \\ 3x+y=16 \end{gathered}$

Solve the system.

$\begin{gathered} 2x+y=12 \\ y=12-2x \\ 3x+y=16 \\ y=16-3x \end{gathered}$ $\begin{gathered} 12-2x=16-3x \\ 3x-2x=16-12 \\ x=4 \end{gathered}$ $\begin{gathered} y=12-2x \\ y=12-2\cdot4 \\ y=12-8 \\ y=4 \end{gathered}$

A small box costs $4 and a large box costs $4 too.
