Answer:
x=y^2-2
Step-by-step explanation:
This graph, is a parabola that opens to the right.
To answer this question, we just use the vertex form of a sideways parabola- x=a(y-k)^2+h.
In this case, the vertex is (-2, 0), and our value of a is 1, since it opens to the right.
This gives us: x=1(y-0)^2+(-2)
Which simplifies to: x=y^2-2.
Also, the answer to the previous two questions are wrong.
The D value (Domain) is actually [2, ∞)
The R value (Range) is actually "All real numbers" (-∞, ∞)
Let me know if this helps!

Answer:
4:3
Step-by-step explanation:
The computation of the ratio of females to males is shown below
Since it is mentioned that there is 28 students in the class out of which 12 are boys
So, the females are
= 28 - 12
= 16
SO, the ratio of females to males is
16:12
4:3
The right answer is Option C.
Step-by-step explanation:
Given word problem is;
Two more than three times a number is at least eight
Let,
n be the number.
Times a number = 3n
Two more means addition;
Two more than three times a number = 3n+2
At least eight means that it can either be 8 or more.
Therefore,
3n+2≥8 is the solution set.
The right answer is Option c.
