Hello! The answer to this question is: A = -2
X always equals 90 in a rhombus and y is 47
Answer:
Step-by-step explanation:
If you plot these points on a coordinate plane, you see that they are on the same horizontal line, y = 7, with the focus 1 unit to the right of the vertex. This means that the parabola is a sideways opening parabola, to the right, to be more specific. That means that it has the basic vertex form

where p is the distance in units from the vertex to the focus, h is the first coordinate in the vertex, and k is the second coordinate in the vertex. For us, p = 1, h = 6, and k = 7. Now we will just fill the vertex form of the equation in with our values:

We will solve this for x now by dividing each side by 4 and adding over the 6:

Answer:
(x, y) = (8, 2)
Step-by-step explanation:
substitute x = 4y into the other equation
2(4y) + 4y = 24
8y + 4y = 24
12y = 24 ( divide both sides by 12 )
y = 2
substitute y = 2 into x = 4y
x = 4 × 2 = 8
solution is (8, 2 )
