Alicia is writing the program for a video game. For one part of the game, she uses the rule
(x, y)→(x−7,y+2)
to move points on the screen.

What output does the rule give when the input is
(−4,−6)
? Show your work.

What output does the rule give when the input is
(2,−9)
? Show your work.

(-11,-4) and (-5,-7)

Step-by-step explanation:

the rule (x,y)→(x−7,y+2) means the x-value of the coordinate decreases by 7, and the y-value of the coordinate increases by two.

Apply the rule to the 1st question by plugging in the coordinates:

(x,y)→(x−7,y+2)

(−4,−6)→((-4)−7,(-6)+2)

(−4,−6)→(-11,-4)

Let's use the same process for the 2nd question:

(x,y)→(x−7,y+2)

(2,−9)→((2)−7,(-9)+2)

(2,−9)→(-5,-7)

why can't you?

step-by-step explanation:

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
