Equation to solve: (72+97+82+p)/4 = 82
72+97+82+p = 82*4 = 328 => p = 328-72-97-82 = 77
3/8=2/4c+10
Multiply all terms by c and cancel:
3c/8=24+10c
(Simplify both sides of the equation)
3/8c=10c+24
(Subtract 10c from both sides)
3/8c−10c=10c+24−10c
−77/8c=24
(Multiply both sides by 8/(-77))
(8/−77)*(−77/8c)=(8/−77)*(24)
c=−192/77
To graph y-3x>-2, find the boundary line. (y > -2 + 3x is your answer)
1. Find the equation of the boundary line.
2. Choose a point (x, y) on the shaded side on the line.
3. Plug x and y, in the boundary to identity the inequality sign.
Answer:
A
Step-by-step explanation:
2x^2-6x+2x-6=2x(x-3)+2(x-3)=(2x+2)(x-3).
