Y= x + 4 2x+3y= -13

What is the solution to the system of equations?

A. (-6, -2)

B. (-5, -1)

C. (1,5)

D. (2,6)

Step-by-step explanation:

Simplifying

2x + 4y = 13

Solving

2x + 4y = 13

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4y' to each side of the equation.

2x + 4y + -4y = 13 + -4y

Combine like terms: 4y + -4y = 0

2x + 0 = 13 + -4y

2x = 13 + -4y

Divide each side by '2'.

x = 6.5 + -2y

Simplifying

x = 6.5 + -2y

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.
