Answer:
the answer is d
x=2y^2
Step-by-step explanation:
The given function is
To the inverse, first we isolate
Then, we change variables
, this is the inverse of the given function.
Now, if you observe the choices, the last one is the inverse
, just move the number two, and it's the same result
Therefore, the right answer is the last choice.
<u>Answer</u>:
x = 7, y = 2
<u>Explanation</u>:
equations given:
x + 7y = 21
x + 4y = 15
make "x" the subject:
x = 21 - 7y .........equation 1
x = 15 - 4y .......equation 2
Solving both the equations simultaneously:
15 - 4y = 21 - 7y
-4y + 7y = 21 - 15
3y = 6
y = 6 ÷ 3
y = 2
If y is 2
Then x = 21 -7y;
x = 21 - 7(2)
x = 21 - 14
x = 7
