Answer:
Hi there I was just working on this question on UsaTestPrep and idk if the answer is really correct but here: C: reflection then rotation.
Step-by-step explanation:
Extra Info:
Dilation is when the shape changes in size, which doesn't happen.
Translation is when it just moves across. It may look like that is happening here, but I'll explain.
The triangle is first reflected along the line . Imaging putting a mirror on the x=0 line (the y axis, basically), and you'd see 1 to 2.
Then, it is rotated around the point . Get a bit of tracing paper, draw over 2, and then, holding the tracing paper down at (works well with a pencil), rotate it round and you will find it fits perfectly over 3.
Also is this the diagram?
For x = 4
7 x 4 + 49 = 77
Answer Is 77
Answer:
r = 46
Step-by-step explanation:
To solve the equation, solve for r by isolating the variable. Whatever you do to one side, do to the other.
1) First, simplify the right side by combining like terms. Subtract the coefficients of the terms with the same variables. Subtract 5r by 4r.
2) Now, finally isolate r by subtracting both sides by 14.

So, r = 46.
