Answer:
x≤0 ⇒|x-3|+5|x| = -6x + 3
0≤x≤3 ⇒ |x-3|+5|x| = 4x + 3
x≥3 ⇒ |x-3|+5|x| = 6x - 3
Step-by-step explanation:
Check the picture below.
A dotted line is not included in the solution so there is no equal sign.
The blue area is to the right of the dotted line so the solution is >
The line crosses the x axis at -2
The answer is : x-y > -2
Answer:
A
Step-by-step explanation:
The equation given in the question has two unknown variables in the form of "x" and "y". The exact value of "x" and "y" cannot be determined as two equations are needed to get to the exact values of "x" and "y". This equation can definitely be used to show the way for determining the values of "x" in terms of "y"and the value of "y" in terms of "x". Now let us check the equation given.
2x - 5y = - 15
2x = 5y - 15
2x = 5(y - 3)
x = [5(y - 3)]/2
Similarly the way the value of y can be determined in terms of "x" can also be shown.
2x - 5y = - 15
-5y = - 2x - 15
-5y = -(2x + 15)
5y = 2x + 15
y = (2x +15)/5
= (2x/5) + (15/5)
= (2x/5) + 3
So the final value of x is [5(y -3)]/2 and the value of y is (2x/5) + 3.
