Solve for the first variable in one of the equations, then substitute the result into the other equation. (4,2) or x=4 y=2
Answer:
Step-by-step explanation:
#Using the method of substitution and replacement of unknown values.
Given that
Express eqtn (ii) in terms of x
Replacing for x in eqtn (i)
Substitute y value in eqtn(ii) to obtain x
We have to identify the statement about the plane which is not true.
1. Consider the first statement,
" A plane can be thought of as flat". It is true as plane is a flat surface.
2. Consider the second statement,
"The surface of a plane is made up of points". It is true as plane is a flat surface which is made up of points.
3. Consider the third statement,
"A plane can be seen". It is not true as plane is a flat surface which can not be seen.
4. Consider the fourth statement,
"A plane extends infinitely in all directions". It is true as plane is a flat surface that extends infinitely along its edges.
