Answer:
b 12
Step-by-step explanation:
Answer:
I = 
Step-by-step explanation:
Given
E = 9RI ( isolate I by dividing both sides by 9R )
= I
Answer:
y = 148°
Step-by-step explanation:
4x - 18 = 2x + 12 (alternate exterior angles are congruent)
Collect like terms
4x - 18 = 2x + 12
4x - 2x = 18 + 12
2x = 20
Divide both sides by 2
x = 10
y = 180 - (2x + 12) (linear pair theorem)
Plug in the value of x
y = 180 - (2(10) + 12)
y = 180 - (20 + 12)
y = 148°
The slope is
(difference in y-values) / (difference in x-values)
= (-4) / (-5)
= 0.8
