Commercial jet's speed = 2x-162 (plug this in the equation below)
Private jet's speed = x
Equation:
10(x) = 8(2x-162)
10x = 16x - 1296
6x = 1296
x = 216 (Private jet's speed)
Take the first equation and plug x value in;
2x-162
2(216) - 162 = 270 ( Commercial jet's speed)

The total number of coins in Lucy's coin collection is equal to 80 coins.
- Let the total number of coins be C.
<u>Given the following data:</u>
- Percentage of quarters = 15%
- Total number of quarters = 12 quarters
To the total number of coins in Lucy's coin collection:
Since the percentage of the quarters in Lucy's coin collection is equal to fifteen percent (15%) of the total number of coins. Thus, we would multiply the total number of coins by 15% and equate it to 12 quarters.
<u>Total number</u><u> of </u><u>coins</u><u>:</u>

C = 80 coins.

Answer:

Step-by-step explanation:
The given function is
If a function reflected over the x-axis, then x-coordinate remains same but the sign of y-coordinate is changed.

If function f(x) is a reflection over the x-axis to get the of g(x), then the resultant function is
Substituting the value of function f(x), we get
Therefore, the required function is
