Answer:y=0 So its A

Step-by-step explanation:3(-y+7)=3(y+5)+6

We move all terms to the left:

3(-y+7)-(3(y+5)+6)=0

We add all the numbers together, and all the variables

3(-1y+7)-(3(y+5)+6)=0

We multiply parentheses

-3y-(3(y+5)+6)+21=0

We calculate terms in parentheses: -(3(y+5)+6), so:

3(y+5)+6

We multiply parentheses

3y+15+6

We add all the numbers together, and all the variables

3y+21

Back to the equation:

-(3y+21)

We get rid of parentheses

-3y-3y-21+21=0

We add all the numbers together, and all the variables

-6y=0

y=0/-6

y=0

The image of C reflected across the line x = 3 would have the coordinates ________________.
kipiarov [429]

Using translation concepts, the image of C reflected across the line x = 3 would have the coordinates (4,-2).

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

The rule for a <u>reflection across the line x = 3</u> is given by:

(x,y) -> (3 + |x - 3| , y).

The coordinates of C are C(2,-2), hence:

(2,-2) -> (3 + |2 - 3| , -2) = (4,-2).

The image of C reflected across the line x = 3 would have the coordinates (4,-2).

Select the coordinates of two points that are on the line x=5
Dmitry_Shevchenko [17]
You can choose the coordinates of any two points on the vertical line where x=5.
So for the coordinates, you need a y value for both. Since the points have to be on that line, you already know that the x value has to be 5.

Using the digits 0, 3, 4, 5 and 6, and any mathematical signs, can you make an expression equal to 8?
Ahat [919]

Answer: 6 + 4 + 3 - 6 - 0

Step-by-step explanation: Add 6, 4, and 3 which gives you 13. Then subtract 5 which gives you 8, then to use all the numbers, subtract 0. There's probably other ways but this is a very simple way.
