What is the image of (0,6)(0,6) after a reflection over the y-axis?
kramer

The image of (0,6) after a reflection over the y-axis is (0, 6)

<h3>How to determine the image of (0,6) after a reflection over the y-axis?</h3>

The point is given as:

(0, 6)

The rule of reflection is given as:

Reflection over the y-axis

The rule of reflection over the y-axis is represented as:

(x, y) = (-x, y)

So, we have:

(0, 6) = (-0, 6)

Evaluate the expression

(0, 6) = (0, 6)

Hence, the image of (0,6) after a reflection over the y-axis is (0, 6)

Solve the equation 2.7 + x = 17
olga55 [171]
Hello!

To solve this equation, we need to isolate the variable on one side of the equation to see what it equals. 

As you can see, 2.7 is added. To get it onto the other side and cancel it from the one side, you will subtract it from both sides as shown below. Note that because of the commutative property, we can switch the places of 2.7 and x.

x+2.7-2.7=17-2.7  (Note that 2.7=2.7 is 0 in this equation.
x=14.3

Our solution is x=14.3

I hope this helped you learn how to solve equations a bit better!

Solve each equation for 0≤x≤360<br> cos(x+45°)+cos(x-45°)= √2
andreev551 [17]

Answer:

0°

360°

Step-by-step explanation:

We want to solve the equation,

\cos(x + 45)  +  \cos(x  - 45)  =  \sqrt{2}

We expand using trigonometric identities to get;

\cos(x) \cos( 45)   -  \sin(x)  \sin(45) +  \cos(x) \cos( 45)    +  \sin(x)  \sin(45)  =  \sqrt{2}

\frac{ \sqrt{2} }{2}  \cos(x)   -   \frac{ \sqrt{2} }{2} \sin(x) +  \frac{ \sqrt{2} }{2}  \cos(x)    +  \frac{ \sqrt{2} }{2} \sin(x)   =  \sqrt{2}

Simplify;

\cos(x)   -  \sin(x) + \cos(x)    +  \sin(x)   =  2

Simplify;

\cos(x)  + \cos(x)  =  2

Add

2\cos(x)  =  2

Divide by 2

\cos(x)  = 1

Take cosine inverse;

In the

x =  \cos^{ - 1} ( 1) =0\degree

Also in the 3rd quadrant cosine ratio is positive.

x = 360-0= 360 \degree
