Answer:

  • Mix A is 2 units
  • Mix B is 1 unit
  • Mix C is 3 units

Step-by-step explanation:

Let amount of Mix A is a, Mix B is b, Mix C is c.

<u>With the given details, we get the following system</u>

  • 5a + 6b + 4c = 28
  • 4a + 2b + c = 13
  • 3a + 4b + 4c = 22

Find the value of c (the easiest one) for substitution

  • c = 13 - 4a - b

Substitute c into the first equation

  • 5a + 6b + 4(13 - 4a - 2b) = 28
  • 5a + 6b + 52 - 16a - 8b = 28
  • - 11a - 2b = 28 - 52
  • 11a + 2b = 24      (5)

Substitute c into the third equation

  • 3a + 4b + 4(13 - 4a - 2b) = 22
  • 3a + 4b + 52 - 16a - 8b = 22
  • - 13a - 4b = 22 - 52
  • 13a + 4b = 30       (6)

Double the equation (5) and subtract (6), find the value of a

  • 2(11a + 2b) - 13a - 4b = 2(24) - 30
  • 22a - 13a = 48 - 30
  • 9a = 18
  • a = 2

Find b

  • 11*2 + 2b = 24
  • 22 + 2b = 24
  • 2b = 2
  • b = 1

Now find c

  • c = 13 - 4*2 - 2*1
  • c = 13 - 8 - 2
  • c = 3

F(x) = x2+ x–1 and g(x) = x+ 3, what is f o g(x)
Naddika [18.5K]

Answer:

Step-by-step explanation:

f(x) = x^2 + x - 1\\g(x) = x +3\\\\\\(f\:o\:g)(x) = f(g(x))

we input the function g(x) into every x in f(x)

f(g(x)) = (x+3)^2 + (x + 3) - 1\\f(g(x)) = x^2 + 6x + 9 + x + 3 - 1\\f(g(x)) = x^2 + 7x + 11
