Answer:
Step-by-step explanation:
Two negative signs equate to a positive sign, so we can write as just :
Add up similar terms:
Add 21 to both sides:
Subtract x from both sides:
Divide both sides by 4:
Answer:y intercept 5
Slope: -3
Step-by-step explanation:
Area of sector =
inches
Answer has been been rounded off to 3 significant figures.
Find slope: (y2-y1)/(x2-x1)
(6-3)/(-5-0) = 3/-5 = -3/5
Equation: y = -3/5x + b
Plug in a point
3 = -3/5(0) + b, b = 3
Solution: y = -3/5x + 3
