Question

What is 4 over -3 multiplied by 4 over 2?

Answer 1

\[\frac{4}{-3} \cdot \frac{4}{2}\]

Answer 2

Multiply the numerator and denominators respectively:\[\frac{16}{-6}\]

Answer 3

I worded that wrong the over should be exponents. So -3 and 2 are the exponents

Answer 4

\[4^{-3} \cdot 4^{2}\] When multiplying two like bases, you add the exponents.

Answer 5

So you will get \(4^{-1}\) = \(\frac{1}{4}\).

Answer 6

Okay last question. Which of the transformations will always produce a congruent figure?
A. a translation. And then a reflection across the x axis.
B.A dialation By a scale factor of two and then a translation
C. A reduction and then a 90° rotation about the origin
D. A reflection and then in enlargement

Answer 7

They must be the same size to be congruent, and only one of those options preserves size.

Answer 8

I don't know. I'm confused

Answer 9

An enlargement, dilation and reduction will all change the size.

Answer 10

Translation and reflection do not affect size.

Answer 11

So it would be A right?

Answer 12

Yeah.
