Answer:
Step-by-step explanation:
A function and its inverse has the following properties
This implies that;
From the table,
This means that:
Note that: f(7) means the value of f(x) when x=7.
From the table f(x)=-6 when x=7.
That is why f(7)=-6.
Answer:
x=35
Step-by-step explanation:
180-147=33 (angles in a straight line)
33+3x+42=180 (angles in a triangle)
3x+42=147
147-42=105
105/3=35
3a =18
3a/3 = 18/3
a = 18/3
a = 6
Hope this helps
The correct answer would be (3x-1)(2x+3)
Answer:
x = 5.142
Step-by-step explanation:
<em>2=-74+14x</em>
if you want to make x the subject (work out its value), you need to single out x
1) the first thing that we can do is get rid of the -74
2) do this by adding it on to both sides of the equation. This is called the inverse
<em>2+-74=-72 -74+14x=14x</em>
<em>-72=14x</em>
3) to get x on its own, we now need to get rid of the 14
REMEMBER:<em> 14x = 14×x</em>
4) We do the inverse by dividing both sides by 14
<em>-72÷14=-5.142..</em>.
its surprising that its not an integer
<em>5.142=x</em>
<em>x=5.142 </em>
PLEASE LET ME KNOW IF THIS IS CORRECT
