Answer:
u = 150
Step-by-step explanation:
Number of vertices:
10
Find the sum of the interior angles:
180(n - 2)
180(10 - 2)
180(8)
1440
To find u:
u = 1440 - (130 + 145 + 160 + 150 + 130 + 150 + 125 + 155 + 145)
u = 1440 - (1290)
u = 150
Answer:
-28x-41
Step-by-step explanation:
6*5x-6*8
30x-48
2x+7-30x-48 = 2x-30x+7-48 = -28x+7-48 = -28x+(-41)= -28x-41
Y=ax+b
a... slope
b... interception on the line y
you get the equation y=-1/2 *x + 12
Just write them the on the other side the exact same way that they are on the Y coordinate hope this helps:)
