Reflect across y axis means that you replace x with -x

f(-x)=2(-x)=-2x
g(x)=-2x
de graph is the one that passes through (0,0) and (1,-2) and -1,2)

For this case we have transformation of functions:

Reflection is the mirror image of a figure. It can also be defined as the turning of points and graphs around the axes.

So, we have:

To graph y = f (-x), the graph of y = f (x) is reflected on the y-axis. (Horizontal reflection)

If f (x) = 2x, to obtain g (x) as a horizontal reflection, we evaluate

g (x) = f (-x)

Thus:

g (x) = f (-x) = 2 (-x)g (x) = - 2x

Answer:

g (x) = - 2x

Check if given set of numbers 6,8,10 forms pythagorean triplet or not?​
kipiarov [429]

\LARGE{ \underline{ \tt{Required \: answer:}}}

We know that,

  • Pythagoras theoram is given by : p² + b² = h²

  • In a Pythagoras triplet, the longest side represents the hypotenuse of the triangle.

Then,

We should check that, whether the sum of squares of the smaller sides will be equal to the square of the third side or not. Then, we can determine the above easily.

Sum of squares of smaller sides:

= 6² + 8²

= 36 + 64

= 100

Square of longer side:

= 10²

= 100

Sum of squares of smaller sides = Square of longer side. Hence, 6,8,10 are Pythagorean triplets.

And we are done! :D

Help with 8 please ASAP
asambeis [7]
Use the equation 459/x=85/100. then you cross multiply 459 and 100 to get 45900. after that you divide 45900 by 85 to get x=540

The perimeter of a stop sign is 96
Fittoniya [83]

Answer:

x = 44

Step-by-step explanation:

4+4+2x+2x= 96

-(add like terms)

8+4x=96

-(subtract 8 from both sides)

4x=88

-(divide by 4 on both sides to get you x alone)

x=44

If y = 8 when x<br> 8 when x = 3, find y when x = 45.
Zarrin [17]

Answer:

y = 120

Step-by-step explanation:

y = kx ur finding k

8 = k 3 get k alone by dividing both sides by 3 --> 8/3 = k

k = 8/3

Y = 8/3 45 now your finding Y when x is 45

Y = 120

to make sure do 120 = 8/3 45 should equal the same
