Equation 1) -4x + 7y = 1
Equation 2) 25 = 2x + 5y
For both equations, move the variables all onto one side, preferably the left side.
To do so, for equation 2, subtract 2x from both sides, as well as subtracting 5y from both sides, and then subtracting 25 from both sides.
2) -2x - 5y = -25
1) -4x + 7y = 1
Multiply all of equation 2 by 2.
2) 2(-2x - 5y = -25)
2) -4x - 10y = -50
1) -4x + 7y = 1
Subtract the equations from each other.
-17y = -51
Divide both sides by -17.
y = 51/17
y = 3
Plug in 3 for y in the first equation.
-4x + 7y = 1
-4x + 7(3) = 1
-4x + 21 = 1
-4x = 1 - 21
-4x = -25
x = -25/-4
x = 25/4
x = 6 1/4
(6 1/4, 3)

The cake could've been cut into 6 equal pieces instead of eight so everyone could have one slice each
hope this helps :)
Answer:
B is the correct option.
Step-by-step explanation:
We have to find the inverse of the logarithmic function
Below are the steps to find the inverse:-
Step 1:-
Set f(x) =y
Step 2:-
Interchange x and y
Step 3:-
Solve for y
We know the relation:-
If
Using this relation, we have
b=2
Step 3:-
The value of y is the inverse of the function.
B is the correct option.
