What is the domain of the function y=-4x-1 when the range is -25

Alborosie

y = -4x - 1

It is a linear function different from the constant function. Therefore, if the range is only one number, then the domain is only one number too.

Let's calculate it:

y = -25 → -4x - 1 = -25 |add 1 to both sides

-4x = -24 |divide both sides by (-4)

x = 6

Answer: The domain = {6}.

5 more than the quotient of a number and 8 is 42

Zepler [3.9K]

Answer:

The number is 296.

Step-by-step explanation:

Let's call "x" to the number we are looking for.

Now, the problem states that "5 more than the quotient of a number and 8 is 42". This means that this number is being divided by 8, it's also being additioned 5 and the final result is 42. Therefore, the expression of this operations on this number is the following:

$\frac{x}{8}+5=42$ . Let's solve the equation to find x.

1. Write the expression.

$\frac{x}{8}+5=42$

2. Substract 5 from both sides and simplify.

$\frac{x}{8}+5-5=42-5\\\\\frac{x}{8}=37\\\\$

3. Multiply 8 on both sides and simplify.

$8*\frac{x}{8}=37*8\\\\x=296$

We have found our number, it's 296!
