Answer:
see first of all it is a quadratic polynomial so it will have 2 zero alpha and beta
now , we will find value of a , b, c
so,
a= 3
b= 5
c= -2
now, sum of the zeros ( alpha + beta) =-b/a
so,-5/3
now product of zeros (alpha *beta) = c/a
so, it will we -2/3
hope you get it !
She needs to earn at least 84 to buy the mp3 player
earnings=earningsperhour times numberofhoursworked
earnings per hour=12 dollars
number of hoursworked=h
therefor
earnings=12 ties h or12h
earnings is at least 84
earnings is greater than or equal to 84
earnings<u>></u>84
12h<u>></u>84
solve
12h<u>></u>84
divide both sides by 12
h<u>></u>7
she needs to work at least 7 hours
to graph, draw a line at x=0 and shade to the right, make the line solid
We will see that the table that correctly describes the distribution is the second one, counting from the top.
<h3>
How to make the table?</h3>
On the top side (horizontal axis) we will have the <u>types of sandwich</u>, while on the left side (vertical axis) we will have the <u>type of bread</u>.
There are simple equations that tell us the distribution of bread.
<u>There are 14 ham sandwiches:</u>
- 7 are on wheat bread
- 3 are on white bread
- 4 are on rye.
<u>There are 20 turkey sandwiches:</u>
- 6 are on white
- 7 are on wheat
- 7 are on rye.
From that, we can see that the correct table is the second one.
