Answer:
the domain is that x is a set of real numbers.
the range is y ≤ -3
Step-by-step explanation:
y = -|x + 3|
y is either positive or equal to zero.
Now, x is all real numbers because any value of x used will yield a valid value of y.
Thus, we can say that the domain is that x is a set of real numbers.
Now, for the range:
The minus sign in front of the absolute value indicates that the function has a maximum value.
Thus, the range is y ≤ -3

Answer:
x = 2/5
Step-by-step explanation:
5x=2
Divide each side by 5
5x/5 = 2/5
x = 2/5
5(6x+5)-2(4x-1) = 30x+25-8x+2 = 22x+27
