Answer:
d < 3
Step-by-step explanation:
Step 1: subtract 4 from both sides
d + 4 < 7 d < 3
Step 2: to plot, make sure the circle is NOT filled because there isn't a line under the sign "<". make sure the arrow is pointing to the left and there is your line :)
Step 3: plug in "3" for "d"
d + 4 < 7 3 + 4 < 7
