A.
rotation 90° clockwise about the origin

B.
rotation 180° about the origin

C.
translation 10 units right

D.
reflection across the y-axis

Answer 1

what happens if you slide the left triangle to right by 10 units ?

Answer 2

oh...... im not awake this morning :/im so sorry that was in plain day there lol

Answer 3

could you help me with some more please :)

Answer 4

you figured out the present problem

Answer 5

yes i did

Answer 6

What is the solution to the equation?
\[4x^2-3=77\]

Answer 7

Choose all answers that are correct.
A. \[5\sqrt{2}\]
B. \[2\sqrt{5}\]
C. \[-2\sqrt{5}\]
D. \[-5\sqrt{2}\]

Answer 8

add 3 to both sides

Answer 9

that is a start

Answer 10

b?

Answer 11

4x^2 - 3 = 77

4x^2 = 80

x^2 = 20

x = +-sqrt(20)
= 2sqrt(5) or -2sqrt(5)

Answer 12

because b = the equation with 3 added to both sides

Answer 13

b and c then

Answer 14

yep

Answer 15

yay!!!

Answer 16

Answer 17

please explain how i would do this i forgot

Answer 18

use pythagoras theorem

leg^2 + leg^2 = hypotenuse^2

Answer 19

x^2 + 12^2 = 22^2

solve x

Answer 20

18.43?.......

Answer 21

rounding to nearest tenth you get

18.4

Answer 22

i suck at rounding even though its so easy for some people

Answer 23

it will be easy if u remember the positions

Answer 24

yeah.......

Answer 25

thank you <3 :)

Answer 26

np

Answer 27

umm i think one more for right now

Answer 28

Which set of side lengths defines a right triangle?

A.
6, 8, 11

B.
5, 12, 13

C.
7, 9, 13

D.
6, 9, 11

Answer 29

i honesty dont even know this

Answer 30

simply use pythagoras theorem

Answer 31

see which lengths satisfy below equation

leg^2 + leg^2 = hypotenuse^2

Answer 32

lets test first option

A.
6, 8, 11

is below true ?
6^2 + 8^2 = 11^2

Answer 33

okay....

Answer 34

umm no

Answer 35

so i find which one is true?

Answer 36

yes, eliminate first option
try second option

Answer 37

B.
5, 12, 13

is below true ?
5^2 + 12^2 = 13^2

Answer 38

that one is true

Answer 39

so thats the answer

Answer 40

awww :( i made a 60%

Answer 41

thats too low
which ones you got wrong

Answer 42

umm i missed #'s 1-4 and 7,8

Answer 43

of course the ones i did by myself :(

Answer 44

oh can u attempt again

Answer 45

no that was the semester final D'X
