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:
x = 7
Step-by-step explanation:
I think there may be other ways to do this ... but this is one I guess....
one angle= 90 ( given)
the other = 45 (given)
the third = 90 + 45 + a = 180
(all angles of triangles is 180 [angle sum property])
a = 180 - 135
= 45
The base angles are equal so that means it is a isoscles triangle. In isoscles triangle, two sides are equal , so
if one side is 7
the x is 7 too
(as it cant be the hypothenus)
I think this is right
Answer:
6y² - 24
Step-by-step explanation:
Expand. Follow FOIL method. FOIL =
First
Outside
Inside
Last.
First, multiply the first term of each parenthesis:
2y * 3y = 6y²
Next, multiply the outside terms from both parenthesis:
2y * 6 = 12y
Then, multiply the inside terms from both parenthesis:
-4 * 3y = -12y
Finally, multiply the last terms of each parenthesis:
-4 * 6 = -24
Combine like terms:
6y² + 12y - 12y - 24
6y² + (12y - 12y) - 24
6y² - 24
6y² - 24 is your answer.
