Answer:
these problems are always tough b/c they want you to translate normal thinking into math jargon :D soooo....
Step-by-step explanation:
they use the point slope formula... which looks like
y = = m(x - )
where ( , ) are the x , y coordinates of some point you're given.. sooo
they give us two points.. so we can put either one of those into the formula.. but we also have to find m.... or the slope ... to find m.. use the slope equation of
m = ( - ) / ( - )
call either point P1 and P2 ... i'll pick the top point as P1 and bottom as P2
then
m = ( -3 -1 ) / ( 1 - 3 )
m = -4 / -2
m = 2 ( yay :) )
now use either point and plug it into the point slope formula, i'll use P1
y - 1 = 2(x-3) ( this is the answer they are looking for )
At the market would be a better deal because u can get it for 4.22$ and at the orchard it would 4.68 per bag so the market is a better deal
<h3>part d is pair of adjacent angle is supplementary </h3>
- because the angle are complementary and common vertex so it is adjacent Two complementary angles with a common vertex and arm are called adjacent complementary angles
hope it's helpful thanks
