When two computers are working together, they can finish updating software in 9 minutes. How long would they take individually t
tensa zangetsu [6.8K]
First computer takes x min. For 1 min it does 1/x part of work.

Second computer takes (x+24) min. For one min it does 1/(x+24) part of work.

Both computers for one min do   (1/x+1/(x+24)) part of work.

At the same time, both computers for one min do 1/9 part of work.

\frac{1}{x} + \frac{1}{x+24} = \frac{1}{9} &#10;\\ \\  \frac{x+24+x}{x(x+24)} =  \frac{1}{9} &#10;\\ \\9(2x+24)=x^{2} +24x&#10;\\ \\ 18x+216=x^{2} +24x&#10;\\ \\ x^{2}+6x-216=0&#10;\\ \\ D=b^{2}-4ac=36+4*216 = 900&#10;\\ \\ x= \frac{-b+/- \sqrt{D} }{2a}  =  \frac{-6+/-30}{2} &#10;\\ \\ x_{1}=-18, x_{2}=12&#10;&#10;We can use only positive number here. So, &#10;&#10;for the first computer x=12 min,&#10;&#10; for second computer x+24=12+24= 36 min&#10;&#10;Answer 12 min and 36 min.

If f(x) is an even function and (6, 8) is one the points on the graph of f(x), which reason explains why (–6, 8) must also be a
Hitman42 [59]

Definition: A function is "even" when f(x) = f(−x) for all x.

Geometrically speaking, the graph face of an even function is symmetric with respect to the y-axis, meaning that its graph remains unchanged after reflection about the y-axis.

If point (6, 8) is one the points on the graph of f(x), then f(6)=8 and since function is even, you can state that f(-6)=f(6)=8. This means that point (-6,8) must also be a point on the graph. Geometrically it means that the output of a negative x-value and its opposite is the same.

Answer: correct choice is A.
