4s + 20 is the correct distribution of the 4.
0.27 because if you put it like a whole fraction it would be 3/11 and as a decimal it is 0.27
The correct answer is h = 9 and k = -8.
While this may seem like a much more complicated problem, the fact is that the vertex of the equation is aways expressed in terms of (h, k). So, since this vertex is already given, we know that the values are simply the values of h and k are simply the x and y values of the vertex. No math is really needed to solve this.
Answer:
see below
Step-by-step explanation:
yes it matters, if you don't know how to write a repeating decimal as a fraction you can use this trick
let's say we don't know what it is
0.33333333...
so we see that there's only one repeating digit
so the answer is
(the repeating digit)/(9)=3/9
and that simplyfies to 1/3
let's try another one
0.67676767...
as you can see know the repeating is 67
so the answer is
(the thing that repeats)/(99)=67/99
do you see a pattern?
when we have a number x of repeating decimals
the denominator of the fraction (the thing that's down) is 9999..99 in there must be x 9's
let me explain
if you have 3 repeating decimals
the denominator will be 999
you see 3 nines
and so on.
First, isolate the x:
5x-2x= 2-3
Then solve!
3x= -1
x= -1/3
Hope this helps!
