The first column. The rule for that column is y = x * -4.
I'm pretty sure that it's k = -1
The answer would be 14/5.
First of all, get the denominators to be the same. The LCM is 5
×
7
=
3/5
So 1
/7
×
5/
5
=
5
/3/5
And 2/
5
×
7
/7
=
14
/35
Now we have 5
/35 and 14
/35
Then all you have to do is divide Joe's by Jane's to get the answer.
14
/35
÷
5
35
=14
/35
×
35/
5
=
14
/5
Meaning the answer is 14/5.
Hope I could help! :)
The answer:
the full question is if f(x) = 3 [ x - 2 ] , what is f(5.9)?
9
10
11
<span>12
</span>first, [x - 2 ] is called the integer part of x-2,
generally, to compute f(c) where c is a real number, it is sufficient to substitute the value of x by c.
so <span>f(5.9) = 3 [ 5.9 - 2 ] = 3 [ 3.9 ]
as we know that </span>[ 3.9 ]=3
<span>
therefore
</span>3 [ 3.9 ]<span>= 3x3 =9
the answer is 9</span>
