Solve the linear equation
9x-2x+6=4x+3x+11-5

0

Step-by-step explanation:

Combine the like terms 9x-2x = 7x

Subtract the numbers 11-5 = 6

Combine the like terms again 4x+3x = 7x

Subtract 6 from both sides of the equation 6-6 = 0 6-6 = 0

Simplify 7x = 7x

Result 0

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest

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.
