1) Given dy / dx = x^2 + 4 = y is the function whose derivative is x^2 + 4.
2) y = x^3 / 3 + 4x + constant
Prove d y / dx = 3x^2 / 3 + 4 + 0 = x^2 + 4
Answer: x^3 / 3 + 4x + C
Answer: a=-6; b=1
Explanation:
This is the same thing as saying -6+1i. Therefore for the general form a+bi, a equals -6 and b equals 1
168.5 / 33.7 = 5
so Tom weighs 5 times as much as Nicholas
Answer:
y = 4x + 5
Step-by-step explanation:
4 times the number of shirts, which is unknown, +$5 no matter how many.
Kaia found a common dividend (if thats the right word), a common factor that both could be divided by, and then did the distributive property backwards pretty much, taking out that common factor from each. You can't use it on that last one because eleven is a prime number (unable to be divided by anything other than one and itself), so the two numbers won't have a common dividor number thingy.
