I do believe that it is the second one I’m not 100% sure but I’m pretty sure it is
Answer:
Step-by-step explanation:
This is a positive parabola so it opens upwards. The equation for the directrix of this parabola is y = k - p. k is the second number in the vertex of the parabola which is (0, 0), but we need to solve for p.
The form that the parabola is currently in is
so that means that
. We can use that to solve for p in the formula
so
which simplifies to
which gives us that
p = 2. Now to find the directrix:
y = k - p becomes
y = 0 - 2 so
y = -2, choice A.
Answer:
In order to out a fraction in lowest terms, you must divide by the Greatest Common Factor, or GCM, of the numerator and denominator in the fraction. Let's say we have the fraction 25/100. We know that the greastest common factor of 25 and 100 is 25, as 25 ÷ 25 = 1 and 100 ÷ 25 = 4 so 25/100 in lowest terms is 1/4:
25 25 1
___ ÷ ___ = ___
100 25 4
If the GCM of a fraction equals 1, the fraction is simplified. Because the only common factor of 1 and 4 is 1, we know this fraction is simplified.
1 1 1
__ ÷ ___ = ___
4 1 4

Answer:
<h3>NO SOLUTIONS</h3>
Step-by-step explanation:
To solve this problem, first, you have to isolate x on one side of the equation.
3x/2-2>7
3x/2-2-7>7-7 (First, subtract 7 from both sides.)
7-7 (Solve.)
7-7=0
3x/2-2-7>0
3x/2-2*0-7*0>0*0 (Then, multiply 0 from both sides.)
0*0 (Solve & simplify.)
0*0=0 (undefined & no solutions)
In conclusion, there are no solutions.
