1) function 2) not a function
the first one is a function because its y values are the same number (3), which means it is a horizontal line and horizontal lines are functions.
the second one is not a function because the coordinates cannot have different inputs but different outputs. each input must have only one output.
the coordinates for the second one are:
(2,5); (1,1); (1,2); (3,2)
and <u>a function cannot have two same x-coordinates</u>. it must pass the vertical line test which is a way to tell if something is a function or not. since the second graph does not pass the vertical line test, it is not a function
hope this helps :)
Good.
She wants to pay 20% down:
= 20 / 100 * 840 = 168.
The remainder = 840 - 168 = 672
She wants to pay the remainder in six equal payments = 672 / 6 = 112.
= $112 (B).
Answer:
b- 13 weeks
Step-by-step explanation:
She makes $550 a week but spends $200 on merchandise so her total weekly is technically $350 in order to earn profit she has to get more than $4500
divide $4500 by $350 which you will get 12.6 but you round it to 13 meaning it would take her a maximum of 13 weeks to receive profit
Area = Area of Rectangle + Area of Triangle
Area = (bh) + (1/2bh)
Area = (9 * 2) + (1/2 * 9 * 6)
Area = 18 + 27
Area = 45 units squared
