Answer:

The number is 57

Step-by-step explanation:

\frac{(n + 6) }{3} = 21\\

3(\frac{(n + 6) }{3}) = 21\\

n + 6 = 63

  - 6    - 6

n = 57

Hope that helps!

Pleaseeee I need help ASAP!!!

Answer:

6 times.

Explanation:

Since she served 3 salads that contain 2/3 cup of blueberries each, and her measuring cup only holds 1/3 cup, she'll have to measure the blueberries 6 times in total, doing 2 measurements per salad (2 x 1/3 = 2/3). Since 2 x 1/3 cup is 2/3 cup, and there are 3 salads in total (multiply 2 measurements by 3 salads), this means she measures the blueberries 6 times.

The graph of y = f(x) is shown. <br> a) Find f(0) <br> 4- <br> 3. <br> b) Give the roots of f(x) = 0
Amanda [17]

The value of f(0) is 1

and

The roots of f(x) = 0 are -2 and -1

<h3>Graph of a function</h3>

From the question, we are to determine the value of f(0) and the roots of f(x) = 0

The value of f(0) is the value of f(x) or the value of y when x = 0

In the given graph, we can observe that the value of y when x = 0 is 2

∴ f(0) = 2

The roots of f(x) = 0 correspond to the values of x when f(x) = 0 or when y = 0

In the graph, we can observe that the values of x when f(x) = 0 are -2 and -1

∴ The roots of f(x) = 0 are -2 and -1

Hence, the value of f(0) is 1

and

The roots of f(x) = 0 are -2 and -1
