Identify the solution(s) of the system of equations, if any. -6x - 4y = 12 12y = -18x - 36

UkoKoshka [18]

$-6x - 4y = 12|\div 2\\
12y = -18x - 36|\div 6\\\\
-3x-2y=6\\
2y=-3x-6\\\\
-3x-2y=6\\
-3x-2y=6$

Both equations are equivalent, so there are infinitely many solutions.

A number n is no less than -3. what is the inequality

vazorg [7]

Answer:

n ≥ -3

Step-by-step explanation:

If n can be no less than -3... then we know that n has to be bigger than or equal to -3.

410.3ft^3. is correct

volume of the sphere with 3ft radius :
$\frac{4 \times \pi \times 3 \times 3 \times 3}{3} = 113$

volume of the sphere with 5ft radius:
$\frac{4 \times \pi \times 5 \times 5 \times 5}{3} = \frac{1570}{3} = 523.3$

difference
$523.3 - 113 = 410.3$

good luck
