Answer:
50 muffins
Step-by-step explanation:
20 : 40%
y : 100%
y · 40 = 20 · 100
40y = 2000
40y ÷ 40 = 2000 ÷ 40
y = 50
Answer:
<u>The correct answer is D. h(x) = 7x – 4x2 – 11x – 17</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
f(x) = 7x – 8x – 2
g(x) = 4x2 + 3x + 15
2. Which of the following answers shows the difference in the amounts of water released, h(x) = f(x) – g(x)?
h(x) = f(x) - g(x)
h(x) = 7x – 8x – 2 - (4x2 + 3x + 15)
h(x) = 7x – 8x – 2 - 4x2 - 3x - 15
h(x) = 7x – 11x – 17 - 4x2
<u>The correct answer is D. h(x) = 7x – 4x2 – 11x – 17</u>
Your post would be clearer if you'd please put each function on its own line:
f(x) = (x + 4)2 + 4
f(x) = –(x + 4)2 + 4
f(x) = (x – 4)2 – 4
f(x) = –(x – 4)2 – 4
Also, use "^2" to denote "squaring." x2 has no meaning.
f(x) = (x + 4)^2 + 4 has a parabolic graph with vertex (-4,4). It increases steadily once x is greater than -4. Reject this choice.
f(x) = –(x + 4)^2 + 4 has a parab. graph with vertex (-4,4) also. It decreases steadily once x is greaster than -4. This is the answer.
Analyze the other 2 possible answers in the same way, please.
