X= 4y+4/3yz this is they solution
x = 8
Since x = 8, you can plug in/substitute 8 for "x" in the equation:



2.82842
2.83 You answer is the 4th option
x = 9
Plug in 9 for "x" in the equation



4 Your answer is the 1st option
Answer:
4c + 6a < = 120 ...4(20) + 6(6) = 116 <== correct
4c + 4a < = 100....4(20) + 4(6) = 104 <== incorrect
first answer choice
Step-by-step explanation:
questions 8, obviously the mid part of the parabola is 3, that is the axis of symmetry.
question 9, only one solution because you only have one parabola.
Answer:
if we are solving for x then it would be
x ≤ −
