Algebra is the devil's arithmetic. I had to repeat it twice bc my teachers were either too lazy to teach it or humilated me.
Answer:
x = 1
Step-by-step explanation:
6(x+4)=30 (divide both sides by 6)
(x+4) = 30/6
x+4 = 5 (subtract 4 from both sides)
x = 5 - 4
x = 1
Answer:
x=-2
Step-by-step explanation:
4(1+3x)=5(x-2)
4+12x=5x-10
12x-5x=-10-4
7x= -14 (after divide 7 on both sides)
7x/7 = -14/7
x= -2
Answer:
see below
Step-by-step explanation:
90 degree clockwise will change x, y coordinates to y, -x
point D 1,3 becomes 3,-1
point E 4, 4 becomes 4,-4
point F 4, -2 becomes -2,-4
point G 1,-1 becomes -1, -1
