The right parenthesis has 4 + 5.
This can be simplified as: 
So, we have:
The left parenthesis has y + 7.
This cannot be simplified because y is a variable and 7 is a number.
<em>Hence, Sierra is correct.</em>
Answer:
A: You plot these points (-3,4) (-3,6) (-5,6) (-7,4)
B: The transformation would be described as a reflection over the y axis
C: The transformation does result in a congruent figure because the shape doesn't change in size or shape and in length or width
Step-by-step explanation:
So our plots from the figure are: (3,4) (3,6) (5,6) (7,4)
So using the rule (x, y) → (-x, y) are new points would be:
(-3,4)
(-3,6)
(-5,6)
(-7,4)
This rule (x, y) → (-x, y) is used for the type of transformation that is a reflection but over the y axis.
Cost of the compact disc player = 50 pounds
Percentage of VAT = 17 1/2%
= 35/2%
Then
Amount of VAT that needs to be given = (35/2)% * 50
= (35/200) * 50
= 1750/200
= 8.75
So the amount of VAT that has to be given is 8.75 pound
Amount that needs to be paid for the compact disc = (50 + 8.75) pound
= 58.75 pound.
So the total amount that needs to be paid for the compact
disc is 58.75 pounds
Answer:
Step-by-step explanation:
(a)
The domain of a function denotes the upper and lower limits of the x co-ordinate values, over which the function is defined.
Here, the x co-ordinates over which the function is defined are from -9 to 7.
Hence ,the domain is: -9 ≤ x ≤ 7
(b)
The range of a function denotes the upper and lower limits of the y co-ordinate values, which the function gives.
Here, the y co-ordinates over which the function gives are from -6 to 4.
Hence ,the domain is: -6 ≤ y ≤ 4
