Move from left to right to find the domain.

Domain: -4 to 2 which is [-4,2]

*For domain and range, brackets are used to indicate that values like -4 and 2 are included in the solution set.

Move from bottom to top to find the range.

Range: -3 to 3 which is [-3,3]

10 - d = -34 - 5d show the work

Naddika [18.5K]

Answer:

d = 11

Step-by-step explanation:

10 - d = -34 - 5d

10 (- d + d) = -34 (- 5d + d)

10 = -34 - 4d

10 + 34 = (-34 + 34) - 4d

44 = 4d

44/4 = 4d/4

d = 11

Zepler [3.9K]

Answer:

<u>The number is 296.</u>

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.
