Answer:

D. 0.925x + 0.88y = 0.91(x + y)  

Step-by-step explanation:

The important point to remember is that the total mass of pure silver is the same on each side of the equation.

0.925x = mass of pure silver in first alloy

0.88  y = mass of pure silver in second alloy

The final alloy has a mass of (x + y) g and is 91 % pure silver, so

0.925x + 0.88y = 0.91(x + y)

What is the end behavior of the function f(x)= -3x^7+4x^5-14?
adoni [48]

Answer:

  • f(-∞) → ∞
  • f(∞) → -∞

Step-by-step explanation:

The degree of the function is odd, so the ends tend in opposite directions. The leading coefficient is negative, so the right end (as x gets large) will tend toward -∞. Then the left end tends toward +∞.

_____

If the degree is even, both ends tend in the same direction. That direction matches the sign of the leading coefficient.

Please HELP!!!!!!! i dont understand this
weqwewe [10]

Answer:

The answer is A, -4.

Step-by-step explanation:

For solving the parenthesis, 2/3 + 2 = 8/3, Since 2 is equivalent to 6/3.

-4 + 8/3 = -4/3. n = 1/3, so the equation would be -4/3 divided by 1/3. that would equal to -4.
