Answer:
x = 14
A = 38
B = 71
C = 71
Step-by-step explanation:
3x-4 + 5x + 1 + 7x-27 = 180
15x-30 = 180
15x = 180 + 30
15x = 210
x = 210/15
x = 14
A = 3x-4 = 3(14) - 4 = 38
B = 5x + 1 = 5(14) + 1 = 70 + 1 = 71
C = 7x - 27 = 7(14) - 27 = 98-27 = 71
Answer: -3/2
Step-by-step explanation: the slope is calculated by the formula:
(y2 - y1)/(x2-x1)
So, (-1-8)/(-3-(-9)) = -9/6 = -3/2
