Answer:
1) congruent
2) corresponding angles
3) 3x+21 = 6x-60
4) x =9
Step-by-step explanation:
1) congruent becuase supplementary means that these 2 angles add up to make 180 degrees.
2) the file below
3) we know they are equal because the congruent correspoding angles.
4) 3x+21 = 6x-60
=> 21 = 9x-60
=> 81 = 9x
=> 9 = x

Answer:
5, 1 , -3 ,-7
Step-by-step explanation:
When x = -1
y = - 4 * (-1) + 1
= 4 + 1
= 5
When x = 0
y = - 4 * 0 + 1
= 0+ 1
= 1
When x = 1
y = - 4 *1 + 1
= - 4 + 1
= - 3
When x = 2
y = -4 * 2 + 1
= - 8 + 1
= - 7
