Linear
Answers that could justify:
the rate of change is constant
The y values decrease by the same amount
As x values increase by 1 the y values decrease by 15
Answer:
Area of 9 cm circle = PI*radius^2 = 254.47
Area of 9 cm sircle = PI*4*4 = 50.27
Are of shaded region = 254.47 -50.27 = 204 sq cm
Answer is the bottom one on the list.
Step-by-step explanation:
Answer:
x = -3±i sqrt(2)
Step-by-step explanation:
x^2+6x + 11 =0
Subtract 11 from each side
x^2+6x + 11-11 =0-11
x^2+6x =-11
Take the coefficient of the x terms
6
Divide by 2
6/2 =3
Square it
3^2 =9
Add it to each side
x^2+6x + 9 =-11+9
x^2 + 6x+9 = -2
The left hand side becomes (x+ (6/2) )^2
(x+3)^2 = -2
Take the square root of each side
sqrt((x+3)^2) = ±sqrt(-2)
x+3 = ±sqrt(-2)
x+3= ±i sqrt(2)
Subtract 3 from each side
x+3-3 = -3±i sqrt(2)
x = -3±i sqrt(2)
