Answer:
square the number in the middle to solve
it's easier than calculating the roots
1) true
2) true
3) false (obviously)
4) false (3² = 9, not less than 9)
5) true
6) true
Answer:
2n+4≤12. n for the number
Step-by-step explanation:
Answer:
All you have to do is divide both sides by 2.5 to find your answer.
2.5x / 2.5 = 35 / 2.5
x = 14
The answer is X = 14.

Answer:
e║f.
Step-by-step explanation:
1) the pointed vectors of the given lines are:
for line e: (3-10;5-8)=(-7;-3);
for line f: (10-3;4-1)=(7;3);
2) -7/7=-3/3=-1, it means the lines are parallel.
The formula for point slope form is (y-y1) = m(x - x1)
In this formula m will always be the slope. So, you can substitute 3 in for m
(y-y1) = 3(x-x1)
y1 is the y-coordinate and x1 is the x-coordinate. So, you can substitute them in and you will be done.
(y - 1) = 3(x - (-2))
But since it is minus a negative it changes to a positive so it would be:
(y -1) = 3(x + 2)
Hope this helps!
