Answer:
(a) 16-2x
(b)-x-2 or x+6
(c)
Step-by-step explanation:
(a)
|6-x|+|x-10|,
|4-x|=4-x,so x<4
|2-x|=x-2=-(2-x)
2-x<0
2<x
or x>2
2<x<4
so |6-x|=6-x,in 2<x<4
|x-10|=-(x-10),in 2<x<4
|6-x|+|x-10|=6-x-(x-10)=6-x-x+10=16-2x
(b)
2-|2-|x-2||,if x<-2
|x-2|=-(x-2) if x<-2
=2-|2-{-(x-2)}|
=2-|2+x+2|
x<-2
x+2<0
=2-|x+4|
=2-(x+4),if x>-4,or -4<x<-2
=2-x-4
=-x-2
if x<-4
then |x+4|=-(x+4)
2-|x+4|=2-{-(x+4)}
=2+x+4
=x+6
Answer:
all of those answers are rational numbers
Step-by-step explanation:
The length is 14 yd and the width is 7 yd because 7•2=14 and 14•7= 128 yd²
I'm going to be making the following assumptions
Assumption 1) The expression M^6+3/Y should be M^6 = 3/Y
Assumption 2) For the equation M^5 = Y^2/6, only the 2 is in the exponent. So it should be written as M^5 = (Y^2)/6
If any of those assumptions are incorrect, then please let me know
--------------------------------
Based on those assumptions, we can divide M^6 over M^5 to get...
(M^6)/(M^5) = M^(6-5) = M^1 = M
So in short, (M^6)/(M^5) = M
We can also say
(M^6)/(M^5) = (3/Y) divided by (Y^2)/6
(M^6)/(M^5) = (3/Y)*(6/(Y^2))
(M^6)/(M^5) = (3*6)/(Y*Y^2)
(M^6)/(M^5) = 18/(Y^3)
Therefore,
M = 18/(Y^3)
So the answer is choice A assuming choice A is saying 18 over Y^3
(again this all hinges on if the assumptions above are correct)
For question 1 it would be 10 hundreds and 2 tens for the second question it would be 13 hundreds
