Using substitution or elimination

9x+3y=-7
y=-3x+4

No solution

Step-by-step explanation:

If we substitute the y into the equation, we get 9x+3(-3x+4)=-7

If we distribute the 3, we get 9x-9x+12=-7

This then cancels out both 9x's and we are left with 12=-7, making it no solution.

No solution

Step-by-step explanation:

Plug in y=-3x+4 into 9x+3y=-7

9x+3(-3x+4)=-7 Distribute the 3

9x - 9x + 12 =-7 Combine like terms

12 =-7 This statement isn't true. Therefore this is system of has no solution. The lines do not intersect.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

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
