Answer:
y=-1/3x-1
Step-by-step explanation:
Perpendicular lines have slope that are opposite sign and reciprocals
3x-y=12 has a slope of 3, therefore perpendicular line must have slope of -1/3
2=-9(-1/3)+b
2=3+b
b=-1
Answer:
1017.36 mm²
Step-by-step explanation:
d = 2r => r = d/2 = 36mm/2 = 18 mm
A = π·r²
= 3.14×(18mm)²
= 3.14×324mm²
= 1017.36 mm²
Answer:
18.
Step-by-step explanation:
Since 2/3 of the pizza has been eaten and 12 slices remain, that means 12 slices comprise one third of the pizza.
So,

Then just divide that by 2.
36/2 = 18

Answer:
146
Step-by-step explanation:
substitute x = 2, y = 3 into the expression
4(2)³ + 2(2)(3) - 2(3) + 3(2)²(3)²
= 4(8) + 12 - 6 + 3(4)(9)
= 32 + 12 - 6 + 108
= 38 + 108
= 146
