slope-intercept form means ' in the form of y=ax+b ' and the answer for this is $y=-\frac{2}{5}x+\frac{6}{5}$

Hi :D How can I help you?

Yes and just type 10+(-2) in your calculator

Logarithmic functions takes the form $f(x)=log_ax$, and if y=$log_ax$, $a^y=x$, and that's why some people say that logarithm is the reverse of exponentiation.

The question didn't mention x, y, and z should be different integers. It is correct that it's the form of Fermat's Last Theorem but the conditions aren't the same or it would be so hard for a student. Therefore geno3141's answer is correct.

$\color{blue} 52-\frac{-80}{-40}+ \frac{-5}{-5}$

$\color{blue}= 52-2+1$

$\color{blue}=50+1$

$\color{blue}=51$

$\color{blue}x^{\frac{a}{b}}= \sqrt[b]{x^a}$

The solution sets are {-1,-1} and {2,5}

$\color{aqua} \frac{21}{4}$

$\color{aqua}= \frac{20}{4}+\frac{1}{4}$

$\color{aqua} = 5 + \frac{1}{4}$

$\color{aqua}=5\frac{1}{4}$
