Step-by-step explanation:
-3x² + 7x + 2 + x³ - x² -9
= x³ -3x² -x² + 7x +2 -9
= x³ -4x² + 7x -7
Answer;
-2.5x-5
Step-by-step explanation:
first multiply whats in the () so -0.5 times 7z = -3.5z + -2 + 1z - -3
then combine like terms -3.5z + 1z = -2.5z
-2+-3= -5 so -2.5z - 5
(-8,1) it being reflected to the other side so just move the points
Note that a:b = c:d is the same as a/b = c/d
y:1.5=0.2:0.75 same as y/1.5 = 0.2/0.75
y = 0.4
x: 1 2/3=y:3 1/3 same as x/1 2/3 = y / 3 1/3
x = y/2 = 0.2
