Answer:
is an irrational number.
is a rational number.
Step-by-step explanation:
Answer: x=5, y=-5, z=6
Step-by-step explanation:
x+y+z=6 -> 2x+2y+2z=12
subtract 2x+4y+2z=2 from this, and you get -2y=10 -> y=-5
So, x+z=11 and -x-3z=-23
x+z=11
-x-3z=23
---------
-2z=-12
z=-6
Meaning x=5.
D:= Driving is difficult
W:= The weather is stormy
The sentence means:
W ==> D
Read as "W implies D"
Which basically just means:
Whenever we have W, we have D, too! Always. We can't have W without also having D.
In this case, we are given W (the weather is stormy). So, we must also have D! (Driving is difficult)
The answer is C.
2x+6 <u>></u> -4
trate it as a temporary equals sign
2x+6=-4
subtract 6 rom both sdies
2x=-10
divide both sides by 2
x=-5
put it back
x <u>></u> -5
so the answer is C
I think is D , hope i answer fast enough haha :D
