x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

x = \frac{-b+/-\sqrt{b^2-4ac} }{2a}     (+/- is this ±)

plug in the numbers into the variables

x = \frac{-3+/-\sqrt{3^2-4(1)(7)} }{2(1)}

x=\frac{-3+/-\sqrt{9-28} }{2}

x=\frac{-3+/-\sqrt{-19} }{2}

your answer is a

What is the solution to this equation? x^2+3x+7=0

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
