Answer:
I think exactly two coz you can decide to use mitric method or elimination method ( I think)
For the answer to the two questions above,
3x + 2y = 36.50 (I)
2x + 5y = 50 (II)
Eliminating x from the two equations by subtraction:
first we multiply equation I by 2 and equation II by 3
6x + 4y = 73
6x + 15y = 150
Subtracting the two,
-11y = -77
y = 7
He earns $7 at the coffee cart
Substituting y into equation I,
3x + 14 = 36.5
x = $7.50
So we can conclude that, he earns a greater wage of $7.50 at the library,
If the function f(x) = 5x – 3, then its inverse function g(x) will be (x + 3) / 5. Then the correct option is C.
<h3>What is
inverse of a function?</h3>
Suppose that the given function is
f:X → Y
Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is
f⁻¹: Y → X
such that:

(and vice versa).
It simply means, inverse of 'f' is undo operator, that takes back the effect of 'f'.
If the f(x) = 5x - 3, then the inverse function of the f(x) will be
g(x) = f⁻¹(x)
Then we have
5g(x) - 3 = x
5g(x) = x + 3
g(x) = (x + 3) / 5
Then the correct option is C.
