<span>Solving for y
</span>
y - 5 = 3(x - 1)<span>
Add 5 to both sides
</span>y - 5 + 5 = 3x - 3 + 5
y = 3x + 2
Your answer: y = 3x + 2<span>

Answer:81
Step-by-step explanation:
9x9=81
Answer:
given that and .
(If these weren't your functions and you understand neither way, please let me know. Thank you kindly. Have a nice day.)
Step-by-step explanation:
.
So here we want to start with the inside first.
That is, start with .
Let then
We need to solve for .
f(c)=2
8c+6=2
Subtract 6 on both sides:
8c=2-6
8c=-4
Divide both sides by 8:
c=-4/8
c=-1/2
Since then .
So now we need to find .
Let then .
So we need to solve for .
Subtract 7 on both sides:
Multiply both sides by 3:
So we have .
----------------Another way!--------------------------
We could actually find the functions that are inverses of the given functions.
The basic idea is that we need to swap x and y:
Now we need to remake y the subject.
Subtract 6 on both sides:
Divide both sides by 8:
is the inverse of .
Again the basic idea to find inverse is to swap x and y:
Now solve for y.
Subtract 7 on both sides:
Multiply both sides by 3:
is the inverse of .
Now let's find:
Answer:
Step-by-step explanation:
Given: In a parallelogram ABCD, diagonals intersect at O and ar(ABCD) is .
We need to find the area of triangle AOB.
We know that each diagonal divide the parallelogram in two equal parts and diagonals bisect each other.
It means both diagonals divide the parallelogram in 4 equal parts.
Hence, the values of ar(AOB) is .
