Answer:
£9.6
Step-by-step explanation:
x = the original price of a CD
£x = 100% of the original price
The price of a CD was decreased by 20% to £7.68.
This means:
£7.68 = 100% - 20%
£7.68 = 80% of the original price
From this, we will find 1% of the original price.
£7.68 ÷ 80 = 1%
£0.096 = 1%
Since the original price ( x ) = 100% of the original price, we will find 100% of the original price.
£0.096 × 100 = 100%
£9.6 = 100%
Therefore, the original price of a CD = £9.6
Answer:
approximately 8.5
Step-by-step explanation:
So you can use the distance formula:
which is derived from the Pythagorean theorem because normally x2-x1 would kind of give the distance length between x2 and x1 except sometimes it would be negative which wouldn't make much sense right? but it doesn't matter because it's being squared so the value ultimately becomes positive, and the same thing goes for the y-value. the distance between x2 - x1 really represents the base and y2-y1 represents the height and then adding them together gives the hypotenuse squared which is why you take the square root over the entire thing to find the distance, since the hypotenuse is the shortest distance between two points
Now all you have to do is plug the values in to get

Answer:
-⅖
Step-by-step explanation:
We need to simplify the given equation and find out the value of a , as ,
=> 3(a-1)+31-11a = 4(2a+3)
=> 3a -3+31-11a = 8a + 12
=> -8a -28 = 8a + 12
=> 16a = -28-12
=> 16a = -40
=> a = -2/5
<h3>
• Hence the value of a is -⅖ .</h3>
Answer:
Option D. The circumference
Step-by-step explanation:
A). Area 'y' of square with side 'x' will be represented by
y = (Side)²
y = x²
Since the degree of this polynomial function is 2, It's a quadratic equation.
B). Area of the circle = πr²
y = π(x)²
Since the degree of this polynomial function is 2, It's a quadratic equation.
C). Volume of a cube = (Side)³
y = x³
Since the degree of this polynomial function is 3, It's not a linear function.
D). Circumference of the circle = 2πr
y = 2π(x)
Since the degree of this polynomial function is 1, it's a linear function.
