I can do my best to help, but I am only taking geometry right now so I might not know all the answers
Answer:
the common factor is: X - 4.
Step-by-step explanation:
( x-4 ) is what the numerator and the denominator have in common.
Answer:
(-2,-3) and (3,2)
Step-by-step explanation:
sub in x-1 into y
x^2 + (x-1)^2 = 13
x^2 + (x-1)(x-1)=13
x^2 + x^2 -2x +1 = 13
2x^2 -2x-12=0
solve for x by factoring (quadratic formula, product sum etc..)
x= -2 and 3
plug in those values into y=x-1 and solve for y
Answer:
High velocity train will take 36.73 hours to travel from Paris and Naples.
Explanation:
Average speed = Distance traveled / Time taken
Time taken = Distance traveled / Average speed.
Distance traveled = 7346 km
Average speed = 200 km/hr.
Time taken = 7346 / 200 = 36.73 hour.
So, high velocity train will take 36.73 hours to travel from Paris and Naples.
-3+2x = -6 (negative and negative changes to positive (+))
2x = -6+3
2x = -3
x = -3/2
