Doug's bar is 50 km away from Ben's bar. let me know if I need to explain.
Step-by-step explanation:
....................
Substitution: n² = t
1 ) t² - 10 t + 24 = t² - 6 t - 4 t + 24 =
= t ( t - 6 ) - 4 ( t - 6 ) = ( t - 6 ) ( t - 4 ) =
= ( n² - 6 ) ( n² - 4 )
2 ) t² - 9 t + 18 = t² - 6 t - 3 t + 18 =
= t ( t - 6 ) - 3 ( t - 6 ) = ( t - 6 ) ( t - 3 ) =
= ( n² - 6 ) ( n² - 3 )
The restrictions: n² ≠ 6, n² ≠ 3, n ≠ +/- √6, n≠ +/-√3
Simplification:
Answer:
D. Angles 4 and 7
Step-by-step explanation:
General equation of line
y = mx + c
Since this line is parallel to y=7x-8
m=7
y = 7x + c
If point (5,-2) is in that line,
-2 = (7*5) + c
-2 = 35 + c
c = -37
so the equation is
y = 7x + -37
