Answer:
Option (D)
Step-by-step explanation:
If a function f(x) is represented on a graph and we follow the transformation as,
f(x) → 
1). If k ≥ 1, graph of the parent function f(x) will be stretched vertically by a factor k.
That means the transformed graph will be narrower.
2). If 0 < k < 1, graph will be vertically compressed or the transformed function will show a wider graph.
Following this rule,
f(x) →
shows k =
[Since 0 <
< 1]
Therefore, transformed form will be wider.
Option (D) will be the answer.
All you have to look at is the word "dropped" and you know it's a subtraction problem. In this case, it would be 8 - 15.
8 - 15 = -7
It would be -7<span>°C at midnight. I hoped this helped! :)</span>
Solve for a.
y=2x/a+2b
Multiply both sides by a.
ay=2ab+2x
Add -2ab to both sides.
ay+−2ab=2ab+2x+−2ab
−2ab+ay=2x
Factor out variable a.
a(−2b+y)=2x
Divide both sides by -2b+y.
a(−2b+y) / −2b+y = 2x / −2b+y
a = 2x / −2b+y
