I’m sorry if that not correct but if it is for you please mark me brainiest.
Answer: So to begin, subtract 4 from both sides of the equation. That makes the equations now -28 + 4y. Divide both sides by 4 to get -7 = y or y = -7
Hope this helps you
Step-by-step explanation:
The first one is x^2 -9x +20
The second one is x^2 -12x +20
The third one is x^2 +x -20
The fourth one is x^2 - 8x -20
Answer:
6. (2,1) 7. (2,2)
Step-by-step explanation:
Number 6, Since it is a dilation of .5 you divide the x and y coordinate by 2 to get (2,1). X - 4/2=2, Y - 2/2=1
Number 7, Since it's rotating 90 degrees counterclockwise you switch the x and y coordinates. So from (x,y) to (y,x) and also when going counterclockwise you have to make the y coordinate becomes negative, so the counterclockwise equation is (-y,x) plug in your numbers and you get (2,2) as your 90 degree counterclockwise rotated coordinates.
