Without more info you cannot answer this question numerically. What is the given value of x?
Let's write y = 5x + 7 as a function: f(x) = 5x + 7.
Now if x=1, f(1) = 5(1) + 7 = 12
If x= -10, f( -10) = 5(-10) + 7 = -50 + 7 = -43
and so on.
The given function is represented by the straight line graph through (0, 7) with slope of 5.
The answer
to do the calculus, the method is
taking off the paranthesis
adding the term with a similar degree
summing constant terms
(3x^2+3x+5) + (7x^2-9x+8) =
= 3x^2+3x+5 + 7x^2-9x+8
= 3x^2 + 7x^2 + 3x+5 - 9x+8
= 10x² + 3x - 9x +5 +8
= 10x² - 6x + 13
the answer is
(3x^2+3x+5) + (7x^2-9x+8) =10x² - 6x + 13
the error that Lucia did make 3x - 9x = -12x, instead of 3x - 9x = -6x
