Triangle XYZ is reflected across the line mc013-1.jpg, and X’ = (2, –15). What are the coordinates of X?

Answers

Answer 1

Answer: The image is not provided, therefore for your understanding, I will assume that the image has been reflected across y-axis (condition taken from a similar question).
There are certain reflection rules across whatever you want to reflect. In this case, we want to reflect the shape across the y-axis.
When you reflect a point across the y-axis, y coordinate remains the same, but the x-coordinate is transformed into its opposite, means the sign of the x coordinate will be changed from positive to negative or negative to positive.
Thus,
(x , y)→(-x , y)

X’ = (2, –15) is the point given to you, which is the reflected point. To find the pre-image, consider the rule described above.

X’ = (2, –15) → X = (-2 , -15)

In case, the question says it is reflected over x-axis then we would use another rule which says When you reflect a point across the x-axis, the x-coordinate remains the same, but y-coordinate is transformed into its opposite, means the sign of the x coordinate will be changed from positive to negative or negative to positive.
Then,
X’ = (2, –15) → X = (2 , 15)

A television cost $375 it is on sale for 25% off and there a 6.5% sales tax

Answers

25% of $375 is:
$375* (25/100)= $93.75.

The cost of the television after sale off and before the sales tax is:
$375- $93.75= $281.25

The sales tax is:
$281.25* (6.5/100)= $18.28

The price of the television including everything is:
$281.25+ $18.28= $299.53

Hope this helps~

A television costs 375 dollars.It is on sale for 25% and there’s a sales tax of 6.5%Let’s calculate to get the answer.Original Price = 375 dollarsLet’s add the 6.5% sales tax=> 6.5% = 6.5 / 100 = 0.065=> 375 * 0.065 = 24.375=> 375 + 27.375 = 399.375Let’s subtract the 25% discount=> 25% = 25 / 100 = .25=> 399.375 * .25 = 99.84375=> 399.375 - 99.84375 = 299.53.Thus the new price of the television is 299.53 with the sales tax and discount.

What is the solution of the system of equations shown below? y = –x + 3
y = 4x – 2

A. (0, 3)
B. (1, 2)
C. (2, 1)
D. (0, −2)

Answers

Answer:

B. (1,2)

Step-by-step explanation:

y = –x + 3.......(1)

y = 4x – 2.......(2)

Putting (1) into (2)

-x + 3 = 4x - 2

4x + x = 3 + 2

5x = 5

x = 5/5

x = 1

And putting x = 1 in (1)

y = -x + 3

y = -1 + 3

y = 2

Answer:

B. (1, 2)

Step-by-step explanation:

YEP!! YOUR ANSWER IS B (1, 2)

Putting (1) into (2)

-x + 3 = 4x - 24x + x = 3 + 2

5x = 5

x = 5/5

x = 1

And putting x = 1 in (1)

y = -x + 3

y = -1 + 3

y = 2
