Will Mark Brainlest help pleaseeeeee

Masja [62]

Answer:

h(2) = 7/4

h(-3) = -2

h(-2) = 11/(-8)

h(-3) - h(-2) = -(5/8)

Step-by-step explanation:

h(x) = (2x^2-x+1) / (3x-2)

h(2) = (2*2^2 - 2 + 1) / (3*2 - 2)

= (8 - 2 + 1) / (6 - 2)

= 7/4

h(-3) = {2*(-3)^2 - (-3) + 1} / {3*(-3) - 2}

= (18 + 3 + 1) / (-9 - 2)

= 22/(-11)

= -2

h(-2) = {2*(-2)^2 - (-2) + 1} / {3*(-2) - 2}

= (8 + 2 + 1) / (-6 - 2)

= 11/(-8)

h(-3) - h(-2) = (-2) - {11/(-8)}

= -(5/8)

Hope this will help. Please give me brainliest.

Dustin has only nickels and quarters in his piggy bank. He has 49 coins total for a combination value of $8.85. How many of each

stepan [7]

Answer: he has 32 quarters and 17 nickels.

Step-by-step explanation:

The worth of a quarter is 25 cents. Converting to dollars, it becomes

25/100 = $0.25

The worth of a nickel is 5 cents. Converting to dollars, it becomes

5/100 = $0.05

Let x represent the number of quarters that he has in her wallet.

Let y represent the number of nickels that she has in her wallet.

He has 49 coins total. This means that

x + y = 49

the total value of the coins is $8.85. This means that

0.25x + 0.05y = 8.85 - - - - - - - - - - 1

Substituting x = 49 - y into equation 1, it becomes

0.25(49 - y) + 0.05y = 8.85

12.25 - 0.25y + 0.05y = 8.85

- 0.25y + 0.05y = 8.85 - 12.25

0.2y = 3.4

y = 3.4/0.2

y = 17

x = 49 - y = 49 - 17

x = 32
