Answer:
the x-coordinates of the intersection point of the lines y = 3x + 5 and y = 2x – 7
Step-by-step explanation:
When you set two equations or functions equal to each other that is saying you want to know when the graphs intersect. So the y and x intercept don't matter, unless you combined the terms like this.
3x + 5 = 2x – 7
x + 12 = 0 then that terms x intercept woudl be the x coordinate of the intersection of the other two terms. But remember, this is onlyif you combines the two functions.
Of your options you just want the ones dealing with the intersection point. And of those two we are plugging in x, so we want the x coordinate.
Answer:
Never
Step-by-step explanation:
It is not possible for one out of two parallel lines to be cut by a transversal, because eventually it would have to intersect
Answer:
With 95% confidence, at least 1,794,000 were tested for HIV within the past 12 months
Step-by-step explanation:
The lower bound of the confidence interval is 29.9%.
So, with 95% confidence, we know that at least 29.9% of the New York population tested for HIV.
Out of 6 million, that is:
0.299*6000000 = 1,794,000
With 95% confidence, at least 1,794,000 were tested for HIV within the past 12 months
