How do I graph y greater than equal to 5

Hatshy [7]

On your graph, draw a horizontal line at y=5. Basically a line over (-3,5) to (3,5) or whatever the greatest x's are. Since it is greater than or equal to, it is a solid line. Greater than, you shade above the line

Serena is building a bookcase she cuts two pieces of wood from one board one piece is 1 7/8 feey long and another is 3.5 ft long

Vladimir79 [104]

Answer:

$\frac{43}{8}$ feet

Step-by-step explanation:

The total change is the sum of the length of two boards she cut.

First board length is 1 7/8th feet. Let's change to improper fraction:

1 7/8 = 15/8 feet

Second board lengrh is 3.5 feet, or 3 1/2 feet. Let's change to improper fraction:

3 1/2 = 7/2 feet

Let's add the two:

$\frac{15}{8}+\frac{7}{2}\\=\frac{15+28}{8}\\=\frac{43}{8}$

The change in original board is 43/8 feet
