Answer: k=9/4
Step-by-step explanation: We can do this by finding a number that adds up to 3 when multiplied by 2. The best way to do this is to use ((b^2)/4) which can usually find you the number for a perfect square based on b, which we have. So, 3^2 / 4 =9/4, meaning k=9/4. We can check:
>x^2 +3x +9/4
> (x+3/2)(x+3/2)
Perfect square.
The value of x is 105 when y=42
Step-by-step explanation:
A direct proportion means that the change in one quantity will also cause the change in other quantity
Given
y varies directly with x
x ∝ y
when the proportionality symbol is removed a proportionality constant is introduced
The value of x is 105 when y=42

Mm im not 100% sure but im pretty sure if you take 10 + 28 and get 38 and then 760 - 38 should be the answer
Soo i think the answer should be 722 meters or whatever
An arithmetic sequence is a sequence where you could add or subtract as the patter stays the same. So, the answer would be (C.) or I and IV because if you take a look at them, for I you add 4 each time and for IV, you add 7 each time. FYI, II is NOT an arithmetic sequence and rather a geometric because every time, the constant is multiplied and not added or subtracted.
