]This problem is for my math class<br> Solve the inequality below<br> 6x - 5 &lt; 55
trasher [3.6K]

Answer: x < 10

Step-by-step explanation: Just like any of your two-step equations, in this inequality, start by isolating the x term which in this case is 6x by adding 5 to both sides.

That leaves you with 6x < 60 and now just divide both sides by 2 and x < 10.

Notice that because we divide both sides of the inequality

by a positive number, not a negative, we did not change the

direction of the inequality sign.

Finally, put your answer in set notation, {x: x < 10}.

Unlike an equation which normally has one solution, the answer to an inequality must be stated as a solution set because an entire set of answers will work. In this problem, it's any number less than 10.

Which option below best describes why the domain of g(x) = 5–x is all real numbers but the range of g is not all real numbers?
Bezzdna [24]
The reason why the domain of g(x)=5⁻ˣ has a domain of all real numbers while the range is not is because, every real number value of x makes perfect sense as an exponent, that means there no restrictions because there are divisions by zero or the square root of the negative number.
The reason why the range is not all real number is because of the negative exponent. This will limit the range to positive real numbers only.
