Question

20 points!! please show me how to do this for d + 4 < 7

Answer 1

Step-by-step explanation:

$d+4$

Solve for d, by subtracting 4 from both sides.

$d+4-4$

$d$

To graph the solution, draw a number line, make a hollow circle on 3 and draw an arrow pointing left towards negative numbers. The circle has to be hollow because the solution does not include 3.

To check your work, substitude d for any number less than 3. In this case, let's try with 2.

$d+4$

This is true. 7 is greater than 6.
