Hello :
f(x) = 4(x2 − 6x + 3² - 3²____) + 20 = 4((x2 − 6x + 3²) - 3²____) + 20<span>
= 4(x-3)² -36+20
</span>f(x) = 4(x-3)² -16 (vertex form)
Answer:
yes it's a refelction over the line f (C)
Step-by-step explanation:
so c is correct
Hey there!
1. 5(s-2) This is because s-2 is the length of each side, and there are 5 sides in a pentagon all of that length, so multiplying it by 5 like this shows its perimeter.
2. 5s-10 This can be found by distributing the first equation, multiplying both s and -2 by 5.
3. (s-2) + (s-2) + (s-2) + (s-2) + (s-2) Each grouping in the parenthesis represents each of the 5 sides, so adding them all together will get you the perimeter.
4. 5(s) + 5(-2) This one is most like the first one, except it's a little more spread out. Multiply the term s by the 5 sides in one grouping, and the integer -2 by 5 in the other.
Hope this helps!

Eliinate y's
multiply top eqatyion by -1 and add to 2nd
9x-2y=24
<u>-x+2y=8 +</u>
8x+0y=32
8x=32
divid both sides b y8
x=4
sub back
-x+2y=8
-4+2y=8
add 4 to both sides
2y=12
divide both sides by 2
y=6
(x,y)
(4,6)
