How long must $542 be invested at a rate of 7% to earn $303.52 in interest? in a easier way

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 9 + 12x + 4x^2

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
