Use the distance formula for the 2 points and then halve the answer
a
7
because 4a + 7 - 7
35 - 7
equals 4a
28
and 4a/4
28/4
equals a
7
60/150 = 40%
Hope this helps :D
The increase in miles would be 11 miles
Answer:
-1
Step-by-step explanation:
2x² - 5x + 7 is subtracted <em>from </em>x² + 2x - 11, so
(x² + 2x - 11) - (2x² - 5x + 7)
x² + 2x - 11 - 2x² + 5x -7 (Distribute the negative)
-x² + 7x - 18 (Combine like terms)
The leading coefficient is the coefficient of the first term, so it is -1.
