Evaluate the following: f(5) = -4x2 + 5x - 1

Step-by-step explanation:

f(5) = -4x2 + 5x - 1

= -4(5)^2 +5(5) -1

= -4(25) +25 -1

= -100 +25 -1

= -76

f(5)=-8 +5×5-1

f(5)=-8+25-1

f(5)=16

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
