The summary of directions of the parabola is:
a) Squared term is x
Parabola either opens up or down.
Positive coefficient means upward opening and negative coefficient means downward opening
b) Squared term is y
Parabola either opens right or left
Positive coefficient means rightwards opening and negative coefficient means leftwards opening
Since the coefficient is positive with squared x term, the parabola opens upward.
So the answer to this question is option D
–6x + 2y = 3/2
or, 2y= 6x + 3/2
or, y= (6x + 3/2)/2
or, y = 6x/2 + 3/4
or, y = 3x + 3/4
Therefore, –6x + 2y = 3/2 is Sandra's equation.
Answer and Step-by-step explanation:
The sides we have are 7, 
, and 
.
The square root of 80 is less than 9 but greater than 8 (because 
is 64, 
is 81, and 80 is in between those two values), and the square root of 31 is definitely less than the square root of 80.
So, is the longest side.
1) The square of is: 
2) The sum of the squares of the two shorter sides is:
3) Since the square of the longest side is equal to the sum of the squares of the two shorter sides, by the Pythagorean Theorem, the triangle is a right triangles.
Hope this helps!

Answer:
x=14
Step-by-step explanation:
1. 4x-24+2=6x-6 Break the parenthesis (distributive property)
2. 4x-22=6x-6 Combine like terms
3. 22=2x-6 Minus 4x to each side
4. 28=2x Add 6 to each side
5. 14=x Divide each side by 2
