Answer:
1.728 × 106 pounds of vegetation
Step-by-step explanation:
From the question, each elephant eats 2.16 × 105 pounds of vegetation per year.
Since there are eight elephants, it will cost a total of 8× 2.16 × 105 pounds of vegetation per year = 1.728 × 106 pounds of vegetation
Move a2 to the left side of the equation so you have c2-a2. then divide by 2 to get b by itself. you are left with c2-a2 all over 2. the 2s will cancel and you'll be left with c-a=b
A week = 7 days
6 inches = 7 days
x = 24 days
cross multiply -> 6 x 24 divide by 7
X - Intercept: 3x + 5y = -15
3x + 5(0) = -15
3x + 0 = -15
3x = -15
3 3
x = -5
(x, y) = (-5, 0)
Y - Intercept: 3x + 5y = -15
3(0) + 5y = -15
0 + 5y = -15
5y = -15
5 5
y = -3
(x, y) = (0, -3)
