Answer:
Step-by-step explanation:
哇，我喜歡吃很多食物，因為我喜歡並喜歡它。
Wa, wǒ xǐhuān chī hěnduō shíwù, yīnwèi wǒ xǐhuān bìng xǐhuān tā.
Usually when you are using the pi term then your round and just use 3.14.
The answer to your question is x is not equal to -3
f(g(x)) = 1/(x-2+5)
= 1/(x+3)
set denominator = 0
x + 3 = 0
x = -3
1 kg of chocolate cookies would cost $5.
Let C be the price of chocolate cookies and A be the cost of almond cookies. The equation for Kay's cookies would be
1C + 2A = 11.
The equation for Zach's cookies would be
3C+1A = 18.
Using Kay's equation, we will get C by itself:
1C+2A = 11
C+2A = 11
Subtract 2A from each side:
C+2A-2A = 11-2A
C=11-2A
Substitute this for C in Zach's equation:
3C+1A = 18
3(11-2A)+1A = 18
Use the distributive property:
3*11 - 3*2A + 1A = 18
33 - 6A + 1A = 18
Combine like terms:
33 - 5A = 18
Subtract 33 from each side:
33 - 5A - 33 = 18 - 33
-5A = -15
Divide both sides by -5:
-5A/-5 = -15/-5
A = 3
Substitute this into Kay's equation:
C+2A = 11
C+2*3 = 11
C+6 = 11
Subtract 6 from both sides:
C+6-6 = 11-6
C=5
