Answer:
48 cubic feet of mulch
Step-by-step explanation:
12 feet long x 4 feet wide x 1 foot deep of mulch= 48 cubic feet of mulch
-3n < 81...divide both sides by -3, change the inequality sign
n > -81/3
n > - 27 <==
** in an inequality, when dividing/multiplying by a negative number, the inequality sign changes
Part a: 30 gallons (i think)
part b: 220
Answer:
y = -3(x + 1)² + 9
Step-by-step explanation:
y = a(x - h)² + k, where (h, k) is the vertex
The vertex of the quadratic function is (-1, 9)
The only equation listed that has a vertex at (-1, 9) is:
y = -3(x + 1)² + 9
