What combination of transformations is shown below?
ozzi

the sequence is:

Translation, then reflection.

The correct option is the second one.

<h3>What combination of transformations is shown?</h3>

We start with figure 1.

In the image, we can see that the image is shifted 4 units up and 4 units left to make figure 2.

Then you can see that the image is reflected across a horizontal line to make figure 3, you can see that because now the "L" is facing upwards.

Then the sequence is:

Translation, then reflection.

The correct option is the second one.

Line equations from point/slope
babunello [35]

Answer:

The answer is

y =  \frac{1}{4} x + 3

Step-by-step explanation:

Plug in and solve the equation. We are trying to find the y-intercept:

y=  \frac{1}{4}x  + b \\  2 =  \frac{1}{4} ( - 4) + b \\ 2 =  - 1 + b \\  \frac{ + 1 =  + 1  \:  \:  \:  \:  \:  \:  \:  \: }{3 = b}

We found the y-intercept, so now we plug it in it's right full spot in the formula.

y =  \frac{1}{4} x + 3

Prove that 1=2 with well arranged steps and justify each step
Shtirlitz [24]
<span>Justification Step 1: Let a = b. Step 2: Then a^2 = ab , Step 3: a^2 + a^2 = a^2 + ab , Step 4: 2a^2=a^2 + ab, Step 5: 2a^2 - 2ab = a^2 + ab - 2ab, Step 6: and 2a^2 - 2a^b = a^2 + ab - 2ab . Step 7: This can be written as 2(a^2 - ab) = 1(a^2 - ab) , Step 8: and cancelling the (a^2 - ab) from both sides gives 1 = 2.</span>
