I think the perimeter is 11x-1y+7, after combining like terms. Not sure about the area though.
Answer:
(3,6)
Step-by-step explanation:
2x-3y = -12
x+y=9. Solve for either y or x
-x. -x
y = -x + 9. Substitute this for the y
2x-3(-x+9)= -12
2x +3x-27 = -12. Add like terms
5x -27 = -12
+27. +27. Inverse operations
5x = 15
÷5. ÷5
x = 3
x + y = 9
3 + y = 9. Substitute 3 for x
-3. -3. Inverse operations
y = 6
-1/3 is the slope of the line perpendicular to k
Answer:
75.7
Step-by-step explanation:
Area of the sector,
17²×π×30/360
= 289π/12
= 75.7 (rounded to the nearest tenth)

568 miles ÷ 21 miles = 27 (fill ups)
$1.02 ÷ 1000 mL = $0.00102 (per mL)
$0.00102 x 3790mL = $3.83 per gallon
$3.83 per gallon x 27 fill ups = $103.40 (rounded) $103.41
