Answer:
<h2>f(x - k) = (x - k)²⇒ k = 5</h2>
Step-by-step explanation:
f(x) + n - shift the graph n units up
f(x) - n - shift the graph n units down
f(x - n) - shift the graph n units to the right
f(x + n) - shift the graph n units to the left
==============================================
Look at the picture.
The graph has been shifted 5 units to the right.
Therefore we have f(x - 5).
Answer: Yes -40 is the answer
Explanation:
-12 = u/8 - 7
8(-12)/8 = u/8 - 8(7)/8
-96/8 = u/8 - 56/8
-96 = u - 56
-u = -56 + 96
-u = 40
u = -40
Always when division with fractions, always move the decimal to the left.
So if she still has $27.12, then during her call, she used a total of $2.88.
$2.88 = 288 cents.
Therefore 288 divided by 6 = 48
Therefore the answer is 48 minutes.
