Answer:
So for the first one the first ting u have to do is FLIP the equation so---> X-12=y
Then you have to add 12 to BOTH sides----> x-12+12=y+12
<u><em>So your answer for X ----> x=y+12</em></u>
<u><em>For Y on the first equation it is--->y=x-12</em></u> (Just flipped and the sign changed)
For the second equation we are gonna solve for Y first.
The first thing u want to do is divide both sides by -3 so it will look like this
-3y/-3 = 2x/+36/-3
<u><em>So Y will equal-----> -2/3x- 12</em></u>
Now we are going to do the X part
So fist FLIP the equation----> 2x+36= -3y
The add -36 to both sides-----> 2x+36+-36=-3y+-36
Last step you have to divide both sides by 2
So that would be----> 2x/2= -3y-3
<u><em>Your final result will be----> x=-3/2y-18</em></u>

Answer:
33.33%
Step-by-step explanation:
The formula for percent change is:
(new - old)/old x 100
= (24 - 36)/36 x 100
= -33.33
There's a -33.33% change, and a 33.33% decrease.
I hope this helped!
Answer:
Step-by-step explanation:
look at each picture to see what they are stating is the same in each of the triangles... the marks thur the lines means they are the same length, or the double or triple arcs in the angles means those are the same. so if there are two sides that are the same... you can say SSS , if there are two angles that are the same you can say ASA . the one where there is one side and one angle the same you can say SAS .... hmmm kinda get it?
Answer:
A.
Step-by-step explanation:
Diameter = 6 cm
SO,
Radius = 3 cm
Now
Slant Height = 5 cm
for Finding the height , We'll use Pythagorean Theorem
c² = a²+b²
5² = 3² + b²
b² = 5²-3²
b² = 25-9
b² = 16
Taking sqrt on both sides
b = 4
So
Height = 4
Now Finding the volume of cone
V = 1/3(πr²h)
V = 1/3(π)(3)²(4)
V = 12π cm³
(8x100)+(8x18)
=800+144
=944
