If f(x) = x + 5, what does f(8) represent?

wel

All you do is plug in 8 for x.

So it f(8) = 8 + 5
which equals 13

2 fractions that equal 3/5

Strike441 [17]

To get Fractions equal, you can multiply the fraction By any number you want: (a/b) = k.(a/b)

So multiply 3/5 by 3: (3/5).3 = 9/15
Multiply it by 2: 2.(3/5) = 6/10

3/5 = 9/15 = 6/10 = 0.6

Hope this Helps! :)

I need help solving. The answer is (2,-6)

faust18 [17]

Since we are given x in terms of y, the most efficient way to solve it would be to substitute in the $\frac{1}{2}y+5$ for x in the second equation. So, we then have:

$2(\frac{y}{2}+5)+3y=-14 \implies \\
y+10+3y=-14 \implies \\
4y+10=-14 \implies\\
4y=-24 \implies \\
y=-6$

So, now that we have our y, we can find x. We can actually use either equation, top or bottom, to find x, but to be efficient we should use the top one since we have x in terms of y, so:

$x=\frac{-6}{2}+5 \implies \\
x=-3+5 \implies \\
x=2$

So, our ordered pair is (2,-6).
