The red graph is the result of a vertical translation, 4 units down, of the black graph.
This means that, whenever the black graph associates

The red graph must associate 4 less to the same input:

So, the equation for the red graph is

or, equivalently,

Answer:
a = 5
Step-by-step explanation:
a +a+4 + 2a-3 = 21
4a +1 =21
4a = 20
a = 5
Answer:
4pi r
Step-by-step explanation:
4 7/8 = 4 14/16 = 78/16
2 7/16 = 39/16
39/16 + 39/16 + 39/16 + 39/16 = 156/16
78/16 + 78/16 = 156/16
156/16 + 156/16 = 312/16 = 19 8/16 = 19 1/2
Answer: 19 1/2 inches
