Answer:
The number of tile for which the cost is same route to nearest tile is 49 .
Step-by-step explanation:
Given as :
The cost which Joshua will pay for tile at one store = $ 0.99 per tile + $ 25 for tile saw
The cost which Joshua will pay for tile at another store = $ 1.50 per tile only
Let The number of tile for which the cost is same route to nearest tile = n
So, According to question
$ 0.99 × number of tile + $ 25 = $ 1.50 × number of tile
or, $ 0.99 × n + $ 25 = $ 1.50 × n
or, $ 1.50 × n - $ 0.99 × n = $ 25
I.e 0.51 × n = $ 25
∴ n =
I.e n = 49.01 ≈ 49
So, The number of tile for which the cost is same route to nearest tile = n = 49
Hence The number of tile for which the cost is same route to nearest tile is 49 . Answer
The answer is option A the points are (-6, -2) and
(-6, -5).
Step-by-step explanation:
Step 1:
To understand reflection across an axis we need to be able to know which quadrant the shape is already in and in which quadrant it will be in after reflection.
The given shape is currently in the second quadrant where the points in it will have a negative x coordinate and a positive y coordinate. So assume the values are in the format of (-x, y).
Step 2:
Due to reflection across the x-axis, the shape will be reflected on to the third quadrant. In this, the x and y coordinates both have a negative value.
So due to reflection, the x value remains constant and the y value remains the same but both have the opposite symbol i.e. negative.
Step 3:
So (-x, y) becomes (-x, -y).
A (-6, 2) becomes (-6, -2),
B (-6, 5) becomes (-6, -5),
C (-3, 4) becomes (-3, -4),
D (-2.5, 2) becomes (-2.5, 2).
So the points are (-6, -2) and
(-6, -5). This is option A.
