The answer is either x>-7 or x<-7 I think it is the first one but I haven’t done these in a while so I forget when to switch the signs
Answer:
$86 is she spending on the party.
Step-by-step explanation:
As per the statement: A company employee is planning a promotion party with her friends. She orders 6 pizzas for $7 each, 2 bowls of mixed salad for $12 each, and 4 cases of assorted soft drinks for $5 each.
⇒ 6 pizzas for $7 each
Total cost for 6 pizzas = 
2 bowls of mixed salad for $12 each.
Total cost for 2 bowls = 
and
4 cases of assorted soft drinks for $5 each.

She spending on party = Total cost for 6 pizzas + Total cost for 2 bowls + Total cost for 4 cases of assorted soft drinks
Substitute the values we get;
Total cost she spending on party = 
Step-by-step explanation:

F ( x ) = - x² + 5 x + 4
between x = 3 and x = 5:
f ( 3 ) = - 3² + 5 · 3 + 4 = - 9 + 15 + 4 = 10
f ( 5 ) = - 5² + 5 · 5 + 4 = - 25 + 25 + 4 = 4
Average rate of change:
( 4 - 10 ) / ( 5 - 3 ) = - 6 : 2 = - 3 feet / sec
