Write the equation in function form: 8x + 4y = 20

1 answer:

3 0

The answer is f(x) = 5 - 2x

Function form means just replace y with f(x).

So given 8x + 4y = 20:

Subtract 8x
4y = 20 - 8x

Divide both sides by 4
y = 5 - 2x

20 because if you take 20 half it that would be 10 then take away 4 that would then equal 6.

Logarithms <br> 8^(x-9) = 19^(3x+2)

Sophie [7]

$\bf 8^{x-9}=19^{3x+2}\implies log(8^{x-9})=log(19^{3x+2})
\\\\\\
(x-9)log(8)=(3x+2)log(19)\impliedby distributing
\\\\\\
xlog(8)-9log(8)=3xlog(19)+2log(19)
\\\\\\
xlog(8)-3xlog(19)=9log(8)+2log(19)\impliedby \textit{common factor}
\\\\\\
x[log(8)-3log(19)]=9log(8)+2log(19)
\\\\\\
x=\cfrac{9log(8)+2log(19)}{log(8)-3log(19)}$
