2(5-x)-15 is greater than 12(x+1)-10(x-3) w

x = - 9  is greater

Step-by-step explanation:

-2(5-x)-15 is greater than 12(x+1)-10(x-3)

-2(5-x)-15

-10 - 2x - 15

-2x -15 -10

-2x -25

x = -25/-2

x = - 12,5

12(x+1)-10(x-3)

12x + 12 - 10x -30

2x -18

x= -18/2

x = - 9

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
