Answer: The correct option is (B) less than 2.
Step-by-step explanation: Given that Y varies directly with X and has a constant rate of change of 6.
We are to find the possible value of X when the value of Y is 11.
Since Y varies directly with X, so we can write
![Y\propto X\\\\\Rightarrow Y=kx~~~~~~~~~~~~~~~(i),~~~~~~~~~\textup{[where 'k' is the constant of variation]}](https://tex.z-dn.net/?f=Y%5Cpropto%20X%5C%5C%5C%5C%5CRightarrow%20Y%3Dkx~~~~~~~~~~~~~~~%28i%29%2C~~~~~~~~~%5Ctextup%7B%5Bwhere%20%27k%27%20is%20the%20constant%20of%20variation%5D%7D)
Since the rate of change is constant and is equal to 6, so we must have
So, from equation (i), we have
Now, when Y = 11, then from equation (ii), we get
Thus, the value of X is less than 2 when Y = 11.
Option (B) is CORRECT.
Answer:
The third one
Step-by-step explanation:
If you look at the graph you see that the relationship between the points is linear positive correlation
Therefore c is your answer :)
Answer:
The answer is 9(x-3).
Step-by-step explanation:
Slope intercept form: y = mx + b
m = slope
b = y-intercept.
We have m which is -2
y = -2x + b
We need to find the y-intercept so plug 6 for x and 7 for y (6,7)
7 = -2 * 6 + b
7 = -12 + b
19 = b
Now put b in the equation
y = -2x + 19
If you are taking the cm to km then it would be like this
4.5km*4.1cm= 18.45km
