Sal is making bracelets for a fundraiser.he uses 6 inches of yarn per bracelets how many bracelets can sal make with 5 feet of y

kodGreya [7K]

Answer:-Sal can make 10 bracelets with 5 feet of yarn.

Explanation:-

We know that 1 foot = 12 inches

⇒1 inch= $\frac{1}{12}\ foot$

Yarn used for 1 bracelet = 6 inches $=\frac{6}{12}\ feet=0.5 foot$

Number of bracelets made in 5 feet $=\frac{5}{0.5}=10$

therefore, Sal can make 10 bracelets with 5 feet of yarn.

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
