If I can write your number as a fraction with whole numbers
on top and bottom, then your number is rational.
1.313233 = 1,313,233 / 1,000,000 yay !
I did it ! Your number is rational.
Here's a hint that will give you the rational/irrational answer
to probably 95% of the examples you ever see:
Any number that you can write down on paper, completely,
using digits (and a decimal point or fraction bar if necessary)
is always rational.
Answer:
last answer:
h(x) = 1/4 x
Step-by-step explanation:
First, change f(x) to y.
f(x) = 4x
y = 4x
Then switch the x and y.
y = 4x
x = 4y
Last, solve for y.
x = 4y
x/4 = 4y/4
x/4 = y
y = x/4
This is the same as:
y = 1/4 x
h(x) = 1/4 x
Here's the answer, using the quadratic formula
B The perimeter is 6x the width.
2(2w)+2w
You would have to combine like terms.
2 times 2w is 4w, then add that to 2w.
4w plus 2w is 6w.
w=width
whole expression=perimeter (P)
P=6w
the perimeter is 6 times the width
srry if the explanation is bad
but its DEFINITELY B.
