PLEASEEE HELP I HAVE NO IDEA ITS DUE IN 10 MIN
hammer [34]

To find out how many students voluteered, simply add the fractions:

\dfrac{1}{3}+\dfrac{1}{4}+\dfrac{2}{6}

Remember that 2/6=1/3, so the sum is actually

\dfrac{1}{3}+\dfrac{1}{4}+\dfrac{1}{3}

We can sum the first and last terms immediately:

\dfrac{2}{3}+\dfrac{1}{4}

And finally, we can change both fractions so that they have the same denominator:

\dfrac{2}{3}+\dfrac{1}{4} = \dfrac{8}{12}+\dfrac{3}{12} = \dfrac{11}{12}

2(x-3)=y+1

Distributive prop.

2x-6=y+1

Changing into slope-intercept form

y+1=2x-6

y=2x-7

The slope is two and the y-intercept is -7
