Answer:
SAS Postulate
Step-by-step explanation:
In EDG & ADC ,
1) AD = ED ( given )
2)angle( EDG ) = angle ( ADC )................ [ Vertical Opposite Angles are equal ]
3) GD = CD ( D is the mid - point of CG )
So triangles EDG & ADC are congruent by SAS postulate....
On a graph, find the point of intersection of two lines; the first line has y-intercept = 5 and slope = −3, and the second line has y-intercept = 2 and slope = 1. Option A is correct.
Given that,
y = −3x + 5 ,
y = x + 2
Which of the following statements best explains the steps to solve the pair of equations graphically is to be determined.
<h3>What is the equation?</h3>
The equation is the relationship between variables and is represented as y = mx + c is an example of a polynomial equation.
Here,
Intersection point of two lines on the graph is system of solution for the pair of the equation,
Thus, On a graph, find the point of intersection of two lines; the first line has y-intercept = 5 and slope = −3, and the second line has y-intercept = 2 and slope = 1. Option A is correct.

When we are given a system of 3 linear equations, with 3 variables, we proceed as follows:
We consider 2 pairs or equations, for example (1, 2) and (2, 3), and eliminate one of the variables in each pair, creating a system of 2 linear equations with 2 unknowns.
Note that the third equation contains -2y which can be used to eliminate easily -6y in the second equation, and -4y in the fourth.
i) consider equations 1 and 3:
-3x-4y-3z=-7
5x-2y+5z=9
multiply the second equation by -2:
-3x-4y-3z=-7
-10x+4y-10z=-18
adding the 2 equations we have -13x-13z=-25
ii) consider equations 2 and 3. Multiply the third equation by -3:
2x-6y+2z=3
-15x+6y-15z=-27
adding the 2 equations we have -13x-13z=-24
So we got -13x-13z is -25, but also -24. this means the system is inconsistent, so it has no solution.
Answer: the system has no solutions
N = x/y because its in the middle
Answer:
its B -15 - 10 = -25
