Answer:

none of the above. (Talk to your teacher about this question.)

Step-by-step explanation:

The differences between length and width are 4, 6, 12, so are not constant at either 4 or 6.

The ratio of width to length is 2/3, 2/3, 3/5, so is not constant at 2/3 or 3/2.

None of the answer choices (even after editing to add appropriate math symbols) describes the relation between length and width.

What is the solution to this system of equations?

murzikaleks [220]

Answer:

(5,1)

Step-by-step explanation:

You already have x isolated in the second one so you just fill that in for the first one and get y+4+y=6. Then you simplify and get that y=1 and because only one of the answer choices shows that, you just pick that choice which is (5,1).

The vertex of this parabola is at (-4, -1). When the y-value is 0, the x-value is 2. What is the coefficient of the squared term

satela [25.4K]

$\bf \qquad \textit{parabola vertex form}\\\\
\begin{array}{llll}
\boxed{y=a(x-{{ h}})^2+{{ k}}}\\\\
x=a(y-{{ k}})^2+{{ h}}
\end{array} \qquad\qquad vertex\ ({{ h}},{{ k}})\\\\
-------------------------------\\\\
y=a(x-(-4))^2-1\implies y=a(x+4)^2-1
\\\\\\
\textit{now, we also know that }
\begin{cases}
y=0\\
x=2
\end{cases}\implies \underline{0}=a(\underline{2}+4)^2-1$

solve for "a"
