Answer: (x) =
Step-by-step explanation:
f(x) = 9x - 8 , to find the inverse of f(x) , replace f(x) with y , then the equation becomes
y = 9x - 8 , then make x , the subject of the formula ,
9x = y + 8
x =
Finally , replace x , with (x) and y with x , so we have
(x) =
(4,6) :)
As it goes over the X axis, you pretty much just mirror it, over that axis.
3+4x=15
4x=15-3
4x=12
x=12/4
x=3
The check is:
<span>If x=3 then, </span>
3+ (4 X 3)=15
<span>3+12=15</span>
Answer:
The equation is:
f(x) = Ix + 3I - 2
Step-by-step explanation:
For a function like:
f(x) = Ix - kI + c
k is the x-value where the vertex is, and c is the y-value where the vertex is.
In the graph we can see that the vertex is in the point (-3, -2)
then:
x-value = -3 = k
y-value = -2 = c
Replacing those in the equation for the function:
f(x) = Ix - (-3)I - 2
f(x) = Ix + 3I - 2
Answer:
OR 5g : 8g
Step-by-step explanation:
Also a ratio can also be represented by a fraction;
So to make the ratio to the simplest form we have to divide by a number that can divide both number.
40g : 64g
We can start dividing by 2 which will give us;
20g : 32g
Now we can divide by 2 again since it can divide both numbers which will give us;
10g : 16g
We can still divide by 2 since it can divide both numbers which will give us;
5g : 8g
Since no numbers can divide 5 and 8 equally that is our answer.
