Hello,

f(x)=-(x-1)²+2 has a vertex (1,2) and this is a maximum because the coefficient of x² is negative.

The vertex of f(x)+3 will be (1,2+3=5)

The greatest value of f(x)+3 is 5

Oh these are easy, I’ll explain.
To start off, the answer is 11.

Given f(x)=3x+8 and g(x)=6x+6<br> then what is (f+g)(−1))?
siniylev [52]
<span>f(x)=3x+8 and g(x)=6x+6

(f + g)(x) = f(x) + g(x)
 
              = </span>3x+8 + (6x + 6) = 3x + 6x + 8 + 6 = 9x + 14<span>

</span>(f + g)(x) = <span> 9x + 14
</span>
(f + g)(-1) = <span> 9*-1 + 14 = -9 + 14 = 5
</span>
<span>(f + g)(-1) = 5</span>

A music website charges x dollars for individual songs and y dollars for entire albums. Person A pays $25.92 to download 6 indiv
Elena-2011 [213]
Let x equals to amount charged for downloading individual songs \Rightarrow y equals to amount charged for downloading an entire album.

Solve the system for y:
\left\{{{6x+2y = 25.92,}\atop{4x + 3y = 33.93;}}\right \left\{{{6x+2y = \frac{648}{25},}\atop{4x + 3y = \frac{3393}{100};}}\right&#10;\\\left\{{{6x+2y-2y = \frac{648}{25}-2y,}\atop{4x + 3y = \frac{3393}{100};}}\right \left\{{{6x = \frac{648}{25}-2y,}\atop{4x + 3y = \frac{3393}{100};}}\right&#10;\\\left\{{{x = \frac{-25y+324}{75},}\atop{4x + 3y = \frac{3393}{100};}}\right \left\{{{x = \frac{-25y+324}{75},}\atop{4\frac{-25y+324}{75} + 3y = \frac{3393}{100};}}\right
\left\{{{x = \frac{-25y+324}{75},}\atop{\frac{4(-25y+324)}{75} * 300 + 3y * 300 = \frac{3393}{100} * 300;}}\right \left\{{{x = \frac{-25y+324}{75},}\atop{16(-25y+324)+900y = 10179;}}\right&#10;\\\left\{{{x = \frac{-25y+324}{75},}\atop{500y+5184 = 10179;}}\right \left\{{{x = \frac{-25y+324}{75},}\atop{500y = 4995;}}\right&#10;\\\left\{{{x = \frac{-25y+324}{75},}\atop{y = \frac{999}{100} = 9.99;}}\right

Solving the system for x is unoptional since we already have the answer we've been looking for. Your answer is 9.99\$.
