Bob's bagels offers pre-paid cards and has the specials shown. carol has a $50 card she uses to buy coffee and a bagel each week. diego has a $60 card he uses to buy tea and a breakfast sandwich each week. write and solve an inequality to find the number of weeks in which the balance on carol's card will be greater than the balance on diego's card.

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

answer: 1.06 km per sec

step-by-step explanation:

39.6 m=63.72 km

60 min in an hour so 63.72/60=1.06
