<span>The final step in this inequality is to make x the subject. To do this, we divide both sides of the inequality by -2. Whenever we mulitply or divide by a negative number in an inequality, we must swtich the sign. So the inequality becomes -6/-2 > -2x/-2 which simplifies to x < 3. The third option is correct.Hope this helps. Let me know if you need additional help!</span>
3yx-1
i think (the -1 is an exponent)
Answer:
3
divide 100 by 30 then take the answer will be 3.3333 since the repeating number isn't 5 or over 5 then u can keep it at 3
Answer:
121
Step-by-step explanation:
dP/dt is propotional to P^½
dP/dt = k(P^½)
When P=100, dP/dt=+20
20 = k(100^½)
20 = 10k
k = 2
dP/dt = 2(P^½)
Reciprocate both sides:
dt/dP = 1/[2(P^½)]
dt/dP = ½[P^(-½)]
Integrate wrt P.
t = ½ [(P^½) ÷ ½] + c
t = P^½ + c
Using t = 0, P =100.. find c
0 = 100^½ + c
0 = 10 + c
c = -10
t = P^½ - 10
Find P when t=1
1 = P^½ - 10
P^½ = 11
P = 121
