Which product is modeled by the number line below?
Gnoma [55]

Answer:

(B)(negative 2) (4)

Step-by-step explanation:

The arrow on the number line ended at negative 8 (-8).

Given the options:

(A) (negative 3) (4) =(-3)(4)=-12

(B)(negative 2) (4) =(-2)(4)=-8

(C) (2)(4)=8

(D)(3)(4)=12

The expected product is -8 since that is where the arrow ended. Therefore, the product that is modeled by the number line is that which gives a result of -8. The correct option is B.

(B)(negative 2) (4) =(-2)(4)=-8

Write an equation for the translation of x^2+y^2=49 by 3 units left and 4 units up
ludmilkaskok [199]
\bf \textit{equation of a circle}\\\\ 
(x-{{ h}})^2+(y-{{ k}})^2={{ r}}^2
\qquad 
\begin{array}{lllll}
center\ (&{{ h}},&{{ k}})\qquad 
radius=&{{ r}}
\end{array}\\\\
-----------------------------\\\\
x^2+y^2=49\iff (x-0)^2+(y-0)^2=7^2\quad 
\begin{cases}
h=0\\
k=0
\end{cases}
\\\\\\
(x-\underline{(-3)})^2+(y-\underline{(+4)})^2=7^2\quad 
\begin{cases}
h=-3\\
k=4
\end{cases}
\\\\\\
\boxed{(x+3)^2+(y-4)^2=49}
