Answer:
X=-2
Step-by-step explanation:
The axis of symmetry for any parabola is the x value of the vertex. Dividing the parabola along the vertex will always yield two symmetric halves.
K = ln(ending amt/bgng amount)/6 years
k = ln(99,000,000/94,000,000) / 6 years
k = ln(

Answer:
a∈(-∝;-17)∩(11;+∝).
Step-by-step explanation:
|a+3|>14; ⇔ 14<a+3<-14; ⇔ 11<a<-17;
Answer:
£480
Step-by-step explanation:
x = the original price of a computer
£x = 100% of the original price
The price of a computer was decreased by 30% to £336.
This means:
£336 = 100% - 30%
£336 = 70% of the original price
From this, we will find 1% of the original price.
£336 ÷ 70 = 1%
£4.8 = 1%
Since the original price ( x ) = 100% of the original price, we will find 100% of the original price.
£4.8 × 100 = 100%
£480 = 100%
Therefore, the original price of a computer = £480
