Answer:
a)7/4= n/12
21=n
b) 8+4y=6
4y=-2
y=-1/2
Step-by-step explanation:
Answer:
Yes.
Step-by-step explanation:
In the Quadratic Equation, <em>y</em><em> </em><em>=</em><em> </em><em>Ax</em><em>²</em><em> </em><em>+</em><em> </em><em>Bx</em><em> </em><em>+</em><em> </em><em>C</em><em>,</em><em> </em>two things could happen with your <em>A</em>:
Opens down → Maximum Value [-A]
Opens up → Minimum Value [A]
We can identify the minimum or maximum value of a parabola by identifying the y-coordinate of the vertex. You can use a graph to identify the vertex or you can find the minimum or maximum value algebraically by using the formula x = ⁻ᵇ/₂ₐ. This formula will give you the x-coordinate of the vertex.
