The answer is 45 muffins
Tasya [4]3 years ago
5 0

Answer:

You started out with 45 muffins

Step-by-step explanation:

If 4/9 is 20, all we have to do if subtract 5 from 20 which would be 3/9. Since 3 is 1/3 of 9, all we have to do now is multiply 15 by 3.

15 × 3 = 45

If f(x) =-2+8 and g(x) = square root of x+9 which statement is true
lidiya [134]

The statement that -6 is in the domain of f(g(x)) is true

<h3>Complete question</h3>

If f(x) = -2x + 8 and g(x) = \sqrt{x + 9, which statement is true?

  • -6 is in the domain of f(g(x))
  • -6 is not in the domain of f(g(x))

<h3>How to determine the true statement?</h3>

We have:

f(x) = -2x + 8

g(x) = \sqrt{x + 9

Start by calculating the function f(g(x)) using:

f(g(x)) = -2g(x) + 8

Substitute g(x) = \sqrt{x + 9

f(g(x)) = -2\sqrt{x + 9} + 8

Set the radicand to at least 0

x + 9 \ge 0

Subtract 9 from both sides

x \ge -9

This means that the domain of f(g(x)) are real numbers greater than or equal to -9. i.e. -9, -8, -7, -6, ...........

Hence, the statement that -6 is in the domain of f(g(x)) is true

Ira Lisetskai [31]

Answer:

   6250

Step-by-step explanation:

Fill in the given number and solve for x. The answer is 1000x, rounded.

  C=\sqrt{0.2x+1}\\\\1.5=\sqrt{0.2x+1} \quad\text{use given value for C}\\\\2.25=0.2x+1 \quad\text{square both sides}\\\\1.25=0.2x \quad\text{subtract 1}\\\\6.25=x \quad\text{multiply by 5}

x is in thousands, so 6.25×1000 = 6,250 passengers flew in June.
