X IS PARTLY CONSTANT AND VARIES PARTLY AS Y WHEN Y IS 10 X IS 24 AND WHEN Y=14, X=36 FIND X WHEN Y=5
x = a + by
so
24 = a+10b
36 = a+14b
subtract and you get
4b = 12
b = 3
now you can find a, and then answer the question.
Can you explain the calculation to me
It's variation.. Then when you are done with the first part... You will have to do simultaneous equation to get the answer ans subtract and substitute in the second part to get x and subtract and you are done
To find the value of X when Y is equal to 5, we need to analyze the relationship between X and Y given the information provided.
From the given information, we know that X is partly constant and varies partly as Y. This means that X is influenced by both a constant value and the variable Y.
Let's first determine the constant value of X. When Y is equal to 10, X is 24. This indicates that when Y increases or decreases from this value, X will also change accordingly. Since the value of X is constant at Y = 10, we can say that the constant value of X is 24.
Next, we need to determine how X varies with Y. We are given that when Y is equal to 10, X is 24, and when Y is equal to 14, X is 36. We can observe that as Y increases by 4 (from 10 to 14), X increases by 12 (from 24 to 36).
To determine the change in X for a change in Y of 1, we can divide 12 by 4. This gives us a change in X of 3 for a change in Y of 1.
Now that we know the constant value of X is 24 and the change in X for a change in Y of 1 is 3, we can find the value of X when Y is equal to 5.
To determine this, we need to calculate the change in X for a change in Y of 5 from the constant Y value of 10. Since the change in X for a change in Y of 1 is 3, we can multiply 3 by 5 to get a change in X of 15.
Finally, to find X when Y is equal to 5, we need to subtract the change in X (15) from the constant value of X (24).
X (when Y = 5) = 24 - 15 = 9.
Therefore, when Y is equal to 5, X is equal to 9.
