- Write the expression you can substitute
for x in 4x + 2y = 3 to solve the system
below.
4x +2y =3
x=4-6y

4(4-6y) + 2y = 3

Step-by-step explanation: Just substitute x into 4-6y multiplied by 4 since x is by itself in the second equation.

y= 13/22

Step-by-step explanation:

x=4-6y

equation: 4x + 2y=3

4(4-6y) +2y = 3

use distributive property

16 - 24y + 2y = 3

Combine and collect like terms:

16 -22y = 3

-22y = 3 - 16

-22y = -13

y= -13/-22

y= 13/22

Hope this helps :)

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

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.
