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

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

it would open into a square depending on the type of envelope i’m not sure about the second part

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
