Answer:
x must be 14/4 = 7/2
Step-by-step explanation:
The sum of the three interior angles of a triangle must be 180 degrees.
Thus, in this particular case,
82 + 64 + 4x + 20 = 180, or
146 + 4x = 160, or
4x = 160 - 146 = 14
Then 4x = 14, and x must be 14/4 = 7/2
Answer:
A = - 2 and B = - 8
Step-by-step explanation:
A = - 2 and B = - 8 will create infinitely many solutions for this system of equations
When you add both equations together and both sides are equal then the systems have infinitely many solutions
-2x - y = 8
2x + y = -8
--------------------Add
0 = 0
Both sides are equal 0
Infinitely many solutions
Answer:
1. B
Step-by-step explanation:
Answer:
A 2-column table with 3 rows. Column 1 is labeled x with entries 12, 18, 22. Column 2 is labeled y with entries 2, 3, 4.
Step-by-step explanation:
cv
A= (-4,2)
The x value (-4) stays the same when reflected over the x-axis, so only the y-value gets reflected and therefore changed.
The resultant coordinate is (-4,2)
