5y - 3x = -47
y = -3x - 13
5(-3x - 13) - 3x = -47
-15x - 65 - 3x = -47
-15x - 3x - 65 = -47
-18x - 65 = -47
<u> + 65 + 65</u>
<u>-18x</u> = <u>18</u>
-18 -18
x = -1
y = -3(-1) - 13
y = 3 - 13
y = -10
(x, y) = (-1, -10)

Answer:
Correct option: C.
Step-by-step explanation:
(Assuming the correct function is R(x) = 2x^2 + 3x + 5)
To find the input value that gives the value of R(x) = 19, we just need to use this output value (R(x) = 19) in the equation and then find the value of x:
Solving this quadratic function using the Bhaskara's formula (a = 2, b = 3 and c = -14), we have:
So looking at the options, the input to the function is x = 2
Correct option: C.
