Answer:
k = -3 or 5
Step-by-step explanation:
The given parameters are;
The line extends from points (-1, 1) to point (2, k)
The length of the line = 5 units
The formula for the length, l, of a line given its coordinates can be found by the following formula;

Therefore, we have;

Which, by squaring both sides, gives;
25 = (k - 1)² + (2 - (-1))² = (k - 1)² + (2 + 1)² = (k - 1)² + 3²
25 = (k - 1)² + 3² = k² - 2·k + 1 + 9
25 - 25 = 0 = k² - 2·k + 1 + 9 - 25 = k² - 2·k - 15
0 = k² - 2·k - 15
0 = (k +3) × (k - 5)
Therefore, k = -3 or 5
When k - -3, we have;

When k = 5, we have;

So basically you start with $25 and then you can multiply 5✖️12 because there is 12 months in a year so then you take the product and multiply it again by 2 and finally you add it to $25.I’m not really good at math but I hope this helps :)
Answer:
He drives at 54 mph. He will get 108 miles if he drives at that rate for 2 hours.
Step-by-step explanation:
9 miles in 1/6 of an hour
9x6=driving speed of 54mph
54x2 is 108 miles
I cant see all the choices but its a quadratic function#
