Pedro made mistake in step 3.
He supposed to plug in y = 12 into the y in the equation to solve for x
Should be:
-14x - 2(2)=24
-14x - 4 = 24
-14x = 28
x = -2
Answer:
volume before reducing is 8 times the volume after reducing
Step-by-step explanation:
volume before reducing=
V=4/3πr³=
V=4/3π(9)³=972π cm³
diameter reduced to half=18/2=9 cm
radius=d/2=9/2=4.5 cm
volume of sphere when diameter reduced by 1/2=
V=4/3πr³
v=4/3 (π)(4.5)³=121.5π
<h2>
volume before reducing is <u>
8</u>
times the volume after reducing</h2>
The answer would c & d in this case
$10.18 Add all the numbers then divide by the amount in this case 5
Answer with Explanation:
If a polygon has symmetry, then it has reflective portion over the line of symmetry.
Note that a rectangle doesn't have the diagonal lines of symmetry since its portion doesn't overlap another.
The simplest symmetry is Reflection Symmetry (sometimes called Line Symmetry or Mirror Symmetry). It is easy to see, because one half is the reflection of the other half.
I hope it will help you.
