Answer:
c
Step-by-step explanation:
A perfect square trinomial is always in the form
(a+b)(a+b)= 
ie. (x+4)(x+4)= 
Answer:
below
Step-by-step explanation:
that is the procedure above
The correct answers are:
- The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true.
- The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.
Further explanation:
Given equations are:
2x-y = -5
x+3y = 22
We have to check whether the given statements are true or not. In order to find that we have to put the points in the equations
Putting the point in 2x-y = -5

Putting the point in x+3y=22

The point satisfies the first equation but doesn't satisfy the second. So,
1. The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true.
This statement is true as the point satisfies the first equation
2. The ordered pair (7, 19) is a solution to the second equation because it makes the second equation true.
This Statement is false.
3. The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.
This statement is true.
4. The ordered pair (7, 19) is a solution to the system because it makes both equations true.
This statement is false as the ordered pair doesn't satisfy both equations.

Step-by-step explanation:
m= (y-y1)/(x-x1)
Points are (-10, -20) and (1, -9)
m= (-20+9)/(-10-1)= (-11)/(-11)= 1
m=1 to replace ? mark
