Set up a proportion:
3/4 = x/12
Cross multiply:
36 = 4x
Divide 4 to both sides:
x = 9
To find the inverse of a function, we swap x and y then solve for y
So with this, we take y = 3x + 4 and make it x = 3y + 4. Now we solve for y
x = 3y + 4
Subtract 4 from both sides
x - 4 = 3y
Divide both sides by 3
The answer may be 9 if I’m correct
Answer:
Step-by-step explanation:it is infinite solution because 15 is equal to 15 if it was like 15=13 it is no solution
I think it’s 3885
Because 6216 divided by 8 is 777, 777x5 is 3885.
I hope that’s right and answers your question
