Knowing the power rule:
dx*n*x^(n-1) all you'd need to do is bring the 7 down and multiply it by -3, then subtract 1 from 7. Because dx is 1 you don't need to worry about it (you'll use chain rule for that)
So your final answer should be dy/dx= -21x^6
Answer: 12 years old
Step-by-step explanation:
10,11,12,12,13,13,14
The middle in these numbers is 12
Answer:
12,500,000. You simply move the decimal point over to the right 7 times.
<span>4(2x - 5) = 4
8x - 20 = 4
8x = 4 + 20
8x = 24
x = </span>

x = 3
Part A:This equation has only one solution. {Working shown above}
Part B:The solution is x = 3. {Working shown above}
0.3 that is bc 3 is not high enough to make it a 4. Hope this helps.
