Solve for x. 7x/3 + 2 = -15<br><br><br>A. -119/3<br>B. -91/3<br>C. -51/7<br>D. -39/7​
Dennis_Churaev [7]

Answer:

<h3>C. -51/7=-7.28</h3>

Step-by-step explanation:

Isolate x on one side of the equation.

7x/3+2=-15

7x/3+2-2=-15-2 (First, subtract 2 from both sides.)

-15-2 (Solve.)

-15-2=-17

7x/3=-17

3*7x/3=3(-17) (Next, multiply 3 from both sides.)

3(-17) (Solve.)

3(-17)=-51

7x=-51

7x/7=-51/7 (Then, divide by 7 from both sides.)

-51/7 (Solve.)

-51/7=-7.28

x=-51/7=-7.28

So, the final answer is (C.) x=-51/7=-7.28.

Write the coordinates of the vertices after a reflection over the line y=3?​
ehidna [41]

Answer:

L(4,-3)  -> L'(4,9)

M(4,3)  -> M'(4,3)

N(-4,3) -> N'(-4,3)

K(-4,-3) -> K'(-4,9)

Step-by-step explanation:

Reflection of an object means to flip that object on a line called the axis of reflection or line of reflection or mirror line.

Line of reflection here is y = 3

So, after a reflection over the line y = 3

Co ordinates

L' =  (4,9)

M' = (4,3)

N' = (-4,3)

K' = (-4,9)
