A) When x is made negative, it gets reflected over the x-axis.

B) When x and y is made negative, it gets reflected over the x-axis and y-axis.

C) Every y-value from the equation would be multiplied by 2, thus changing the shape of the graph. The slope is divided by 2.

D) Every x-value from the equation would be multiplied by 2/3, thus changing the shape of the graph. The slope is divided by 2/3.

E) x-values are divided by 2 and y-values are multiplied by 1.5.

So if talking about points on a graph then
a. x is made negative or opposite of what it is
basically, the x point would go x units from the zero line in the other way it is currently ie. reflected across the x axis

b. both x and y are positive,
basically the figure would be reflected across the x axis then reflected across the y axis (or y axis then x, doesn't matter)

c. y times 2
y is 2 times as high (gets bigger)

d. 2/3 times x
x is 2/3 as much as it was before (gets smaller)

e. 1/2 x and 1.5 y
x get's half smaller and y gets 1.5 bigger (x gets smaller, y gets bigger)

Is ΔFGH~ΔJKL? If so, identify the similarity postulate or theorem that applies.
Aleks [24]

Answer:

Correct choice is  C. Similar AA.

Step-by-step explanation:

We have been given a picutre of the triangles. Using those information we need to find the correct choice.

Consider triangle FGH and triangle JKL.

∠F≅∠J  {Both are equal to 30°}

∠H≅∠L  {Both are equal to 50°}

Then triangle  FGH is similar to the triangle JKL by AA - similarity of the triangle. Because we are getting two congruent angle pairs.

Hence correct choice is  C. Similar AA.

Let a_n be the n th digit after the decimal point in
WITCHER [35]
I believe this should just be equal to<span>
9π+5e−<span>(<span>⌊9π+5e⌋</span>)</span>=9π+5e−41</span>
The first element in your sum should be the first digit after the decimal point times .1, so you have
.8
The next element in the sum is the second digit after the decimal place times .01, so you get<span>
.8+.06=.86

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
