Answer:
The correct answer is 48, given by option c.
Step-by-step explanation:
This question can be solved by proportions, using a rule of three.
Positive correlation means that the variables are directly proportional, and thus, we apply cross multiplication.
If v is 24 when u is 10, which of these is most likely to be the value of v when u is 20?
24 - 10
x - 20
Applying cross multiplication:
Simplifying both sides by 10:
The correct answer is 48, given by option c.
Answer:
y-intercept: (0, 12/5) or (0, 2.4)
x-intercept: (12/7, 0) or (1.714, 0)
Step-by-step explanation:
The y-intercept is the point where the graph crosses the y-axis. That means, the point (0, yi). To find yi, we have to substitute x by 0 in the equation.
7x + 5y=12
7*0 + 5y = 12
y = 12/5 = 2.4
y-intercept: (0, 12/5) or (0, 2.4)
The x-intercept is the point where the graph crosses the x-axis. That means, the point (xi, 0). To find xi, we have to substitute y by 0 in the equation.
7x + 5y=12
7x + 5*0 = 12
x = 12/7 = 1.714
x-intercept: (12/7, 0) or (1.714, 0)
Finally, the graph is shown below.
