a. x=0
b. y=0
c. y=x
d. y=-x

In The Figure Shown, Triangle RST Undergoes Reflections Across Two Line. R''S''T Is The Final Image Of

Answers

Answer 1
Answer: D.  y = -x

======================================================

Explanation:

Point T is at (-2,1)

When we reflect it over the line x = 0, aka the y axis, we use the rule [tex](x,y) \to (-x,y)[/tex] so T(-2,1) becomes T ' (2, 1). The x coordinate flipped in sign, while the y coordinate stays the same.

Then the final transformation is reflecting over y = -x using the rule [tex](x,y) \to (-y, -x)[/tex]. Therefore, the point (2,1) moves to (-1, -2) which is where T'' is located in the diagram.

You apply the same two transformations for the points R and S to get R'' and S'' respectively.

Note: A composition of two reflections, where the lines of reflection aren't parallel, form a rotation. In this case, we have a 90 degree counterclockwise rotation when going from triangle RST to triangle R''S''T''.

The expression (3+i)(1+2i) can be written Jim the form a +bi, where a and b are integers. What are the values of a and b?

Answers

Answer:

a = 1

Students are auditioning for a school play. Only 18 of the 45 students
auditioning will get a part in the play. What percent of the students
who audition will be in the play?

Answers

it should be 40%, you convert 18/45 to a decimal then multiply by 100

The students who audition will be in the play is 40%

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given that Students are auditioning for a school play

Only 18 of the 45 students auditioning will get a part in the play.

We need to find the percent of the students who audition will be in the play.

45x=18

Divide both sides bby 45

x=18/45

x=0.4

Now multiply with 100 as it is hundredth part

0.4×100=40%

Hence, the students who audition will be in the play is 40%

A linear function is a function that creates a straight line when graphed. The difference between this graph and others is that this function is constant instead of curved. I’d like to see an example of this in the real world as a relationship between profit and merchandise.A quadratic function is a function that has multiple variables allowing the graph to curve. The difference between this function and the others is that this function is squared allowing for a greater curve that looks like a U.
