inn [45]

Step-by-step explanation:

U should use the system of 2 equations.

Let x be the rental cost of a movie and let y be that of video games.

{12x + 2y= 41} eq1

{3x + 5y= 35}eq2 note: eq means equation

The answer is

X=2.5 Y=5.5

So, the rental cost for each movie is 2.5$

and for each video game is 5.5$

Andy completes the square for the equation x2 + 6x - 8 = 0. Which of the following equations reveals the vertex of the parabola?

Stolb23 [73]

If the equation $x^2+6x-8$ has undergo completing the square, the answer would be:
$x^2+6x-8
$
$x^2+6x+9-8-9$
**In this example, since 6x is the middle term, what comes to my mind is the polynomial (x+3) because 2ab results into 6x. [from the special products lesson $(a+b)^2=a^2+2ab+b^2$ ]
$(x+3)^2 -17 = 0$
So if the equation is equal to y, then this equation's
$y+17=(x+3)^2$
The vertex would be on the point (-3, -17)
