Answer:
-17/2 =x
Step-by-step explanation:
9–5(x+4)=3(2–x)
Distribute
9 - 5x - 20 = 6 -3x
Combine like terms
-5x-11 = 6-3x
Add 5x to each side
-5x-11 +5x = 6-3x+5x
-11 = 6+2x
Subtract 6 from each side
-11-6 = 6+2x-6
-17 = 2x
Divide by 2
-17/2 = 2x/2
-17/2 =x
36 and 12
36+12=48 and 36-12=24
Michelle's result shows f(2) = -13, selection C.
Answer:
negatively charged
Step-by-step explanation:
Beck add like terms so you get
4x^2 -4x-15
lucy factor our negative so you left with -4x^2 +5x -10 +8x^2 -9x -5
simplify 4x^2 -4x -15
therefore both students answers simplify to 4x^2 -4x -15
