To get the inverse of a function interchange
the x's with the y'x and solve for y, as follows:
y=5x-7
Interchange to get:
x=5y-7
Solve for y to get:
y=(1/5)x+(7/5)
so I think it might be c
Answer:
pizza parlor to ferris wheel
pizza parlor to bumper cars
Step-by-step explanation:
First set up the equation (sum of the angles is 180)
2x + 2(x-1) + (5x +2) = 180
distribute:
2x + 2x -2 + 5x +2 = 180
combine like terms:
9x = 180
solve for x:
x = 20
SO:
2x° = 2(20) = 40 degrees
2(x-1)° = 2(20) - 2 = 40 - 2 = 38 degrees
5x + 2°= 5(20) + 2 = 100 + 2=102 degrees
check: 40 + 38 + 102 = 180
<h2>727</h2>
Step-by-step explanation:
Let us denote the three digit number by 
, where 
is the hundreds digit, 
is the tens digit and 
is the ones digit.
Hundreds digit = = Ones digit =
Sum of digits = 
So, 
On exchanging tens and ones digit, value increases by 45. So 
is 45 greater than .
∴ Required number is 727
