Answer:
-120-x
Step-by-step explanation:
Given:

This is the same as previous one. Recall modulus property:

Keep in mind that |x+a| and |a+x| are equal via addition property.
Since the question gives interval of x < -120:
Therefore, the expression is -120-x
Answer:
120 cubes are required.........
Answer:
(0,3) is the solution set for given system.
Step-by-step explanation:
Given that:
3x+4y=12 ------- eq1
2x-3y= -9 ------- eq2
Multiplying eq1 with 2 and eq2 with 3 we get:
6x + 8y = 24 --------- eq1
6x - 9y = -27 -------- eq2
Subtracting eq2 from 1 we get:
17y = 51
Dividing both sides by 17 we get:
y = 3
Putting value of 3 in eq1 we get:
3x + 4(3) = 12
3x + 12 = 12
3x = 0
Dividing both sides by 3
x = 0
So the solution set will be: (0,3)
i hope it will help you.
