9x^2+24x+24x+64=
9x^2+48x+64
Answer:
Corresponding angle theorem, vertical angle theorem, and the transitive property of congruence.
Step-by-step explanation:
Considering a set of parallel lines cut by a transversal. (Refer the attached image).
Now that lines J and K are parallel, then by "corresponding angle theorem"
By "vertical angle theorem"
Using, "transitive property of congruence"
And that is our required proof. In this whole proof we have used "corresponding angle theorem", "vertical angle theorem", and the "transitive property of congruence".
Answer:
y = all real numbers
x = all real numbers
In set notation/interval notation;
y∈(-∞,∞)
x∈(-∞,∞)
Step-by-step explanation:
1. Background information
The process of elimination involves manipulating an equation such that when the equations in the system are added, one variable is eliminated. Then one can solve for the other variable, finally, one substitutes the answer back in to find the eliminated variable. Therefore solving the system of equations.
2. The given information
Given the system;
(1) 4x + 5y = 4
(2) 8x + 10y = 8
3. Solving
Multiply the first equation by (-2)
4x + 5x = 4
*-2 *-2
-8x - 10x = -8
Add the first and second equations.
-8x - 10y = -8
+ ( 8x + 10y = 8 )
_____________
0
This means that y can be any real number, and hence x can be any real number.
