3. what is the equation of the line shown in the graph below?
(1) y = 2x+4
(3) y=-x-2
(2) y = 2x-2
(4) y = x + 4

Combine like terms to make a simpler expression 3z+z

Atransformation t : (x,y) (x-5,y +3) the image of a(2,-1) is

Without any equipment, you can see stars that are 2{,}800{,}0002,800,0002, comma, 800, comma, 000 light-years away. by looking through a small telescope, you can see stars that are 3{,}112{,}000{,}0003,112,000,0003, comma, 112, comma, 000, comma, 000 light-years away. approximately how many times as far can you see using a small telescope as without any equipment?
