Solve the following nonlinear system algebraically.

x=-1,y=7

x=-3,y=3

Step-by-step explanation:

y=2x+9

5x^2+(2x+9)^2=54

0=(3x+9)(3x+3)

x=30

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
