Answer:

I am not exactly sure what the problem is asking. If the output of the equation f(x)= x+5 is 2 then the input would be -3.

The ratio of the sides of a triangle is 8:13:11. If the perimeter of a triangle is equal to 256, what is the length of the longe

s344n2d4d5 [400]

There asking what the numbers are by The ratios, what I did was did was multiply by 8 for each number 8•8=64 13•8=104 11•8=88 so now what you do is add up 64+104+88=256 those are your answers if you want to double check you will dived them by 8 so 64/8=8 104/8=13 88/8=11
Hope this helps :-)

The vertex of the parabola below is at the point (-4,-2) wich of the equations below could be the one for this parabola

MrRissso [65]

The parabola with with a vertex at (-4,-2) represents any member of parabolas with the equation $y(x)=a(x+4)^2-2$ where $a$ is any real number with the exception that $a\neq 0$ .

The reason any equation of the form $y(x)=a(x+4)^2-2$ works is that there are an infinite number of parabolas with a vertex at (-4,-2). All of these parabolas are formed by applying some transformation that involves a vertical translation of -2 and a horizontal translation of -4 on the parabola $y=x^2$ . The different variations are archived by varying the constant $a$ . When $a$ is negative, the parabolas will face downwards. When $a$ is negative, the parabolas will be face downwards.
