Answer:

x = 9

y = 6

Step-by-step explanation:

  1. Divide 15 by 2: 15 ÷ 2 = 7.5
  2. Subtract 0.5 from 7.5 (this will later be added back): 7.5 - 0.5 = 7
  3. Subtract 1 from 7 (she wants to buy at least 2 more children books): 7 - 1 = 6
  4. Subtract 6 from 15 (6 being the number of puzzle books, 15 being the total number of items): 15 - 6 = 9 (number of children books)

3x-9 when x=3<br> Solve this
Citrus2011 [14]

Answer:

0

Step-by-step explanation:

3x - 9 if x = 3

Substitute:

3(3) - 9 =

9 - 9 = 0

This can be written as a function: f(x) = 3x - 9

f(3) = 3x - 9

f(3) = 3(3) - 9

f(3) = 9 - 9

f(3) = 0

Let g be the piecewise defined function shown.
gogolik [260]
For this case we have the following function:
 g(x) =  \left \{ {{x+4} \atop {2-x}} \right.
 For each of the domains we will choose a value.
 We have then:

 For −5 ≤ x ≤ −1
 Let's choose the value of x = -3 
 Evaluating the function we have:
 g(x) = x+4&#10;&#10; g(-3) = -3+4&#10;&#10; g(-3) = 1
 Answer:
 
g(-3) = 1
 
 For −1 < x ≤ 5:
 
Let's choose the value of x = 0
 Evaluating the function we have:
 g(x) = 2-x&#10;&#10; g(0) = 2-0&#10;&#10; g(0) = 2
 Answer:
 
g(0) = 2

How to write  9/18 into a equivalent fraction
scoundrel [369]
There are many ways. \frac{9}{18} is actually the same as \frac{1}{2} so anything you do just has to have a numerator exactly half as the denominator. So one that would work is \frac{18}{36} I just doubled both numbers. Other ones would be \frac{5}{10}  and  \frac{6}{12} all of which the numerator is exactly half the denominator.
