Which statement can be modeled by 15 -2x < 3x + 10 ? A Sam has 15 water bottles and is throwing out 2 each day. David has 10 water bottles and is collecting 3 each day. When will Sam have fewer bottles than David? B Sam has 15 stamps and is collecting 2 a week. David has 10 stamps and is collecting 3 a week. When will Sam have less stamps? C Sam has 2 water bottles and is throwing out 15 each day. David has 3 water bottles and is collecting 10 each day. When will Sam have fewer bottles than David? D Sam has 2 stamps and is collecting 15 each day. David has 10 stamps and is collecting 3 each day. When will they have the same amount of stamps?

f

step-by-step explanation:

f

the answer is 62

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
