Answer:

g(x) - h(x) =  { - x}^{4}  - 11x

Step-by-step explanation:

g(x) =  {6x}^{2}  - 4x +  {3x}^{4}

h(x) =  {6x}^{2}  + 4 {x}^{4}  + 7x

g(x) - h(x)

({6x}^{2}  - 4x +  {3x}^{4})  - ( {6x}^{2}  + 4 {x}^{4}  + 7x)

{6x}^{2}  - 4x +  {3x}^{4}   - {6x}^{2}   -  4 {x}^{4}   -  7x

( {3x}^{4}  -  {4x}^{4}) +  ( {6x}^{2}  - 6x {}^{2} ) + ( - 4x - 7x)

{ - x}^{4}  - 11x

A bolt has 16-1/2 turns per inch. How many bolts would be in 2-1/2 inches?
ohaa [14]

Answer:

41 1/4

Step-by-step explanation:

Change 16  1/2 to a mixed number

16 1/2 = (2*16+1)/2 = 33/2

Change 2 1/2 to a mixed number = (2*2+1)/2 = 5/2

Multiply the turns per inch by the inches

33/2 * 5/2 =165/4

Change this back to a mixed number

4 goes into 165 41 times

41*4 = 164   there is 1 left over

41 1/4

Kate and Melisa both went to the same store to buy eggs and bread for their families. Kate bought 3 cartons of eggs and 5 loaves
VMariaS [17]
Write an equation system based on the problem
For an instance, e stands for the price of a carton of eggs, and b stands for the price of a loaf of bread

"Kate bought 3 cartons of eggs and 5 loaves of bread for $30.07" could be written as 3e + 5b = 30.07 (first equation)
"Melissa bought 2 cartons of eggs and 2 loaves of bread for $14.74" could be written as 2e + 2b = 14.74 (second equation)

Solve the equation system using elimination method
Eliminate b to find e. To eliminate b, we should equalize the coefficient of b.
3e + 5b = 30.07 (multiplied by 2)
2e + 2b = 14.74 (multiplied by 5)
-------------------------------------------
  6e + 10b = 60.14
10e + 10b = 73.70
------------------------- - (substract)
-4e            = -13.56
   e            = -13.56/-4
   e            = 3.39

The price for a carton of eggs is $3.39
