Ineed some with this question: the movieplex theater sold 1,456 tickets. the theater sold 6 times as many regular price tickets as it sold discount tickets. earl says that the expression 1456 divided by 6 give the number of discount tickets. is earl correct? if not, write the correct expression. explain your answer.

Earl isn't correct: the number 1,456 represents the total number of tickets sold, rather than simply six times the number of tickets sold.

Let x= the discount ticket price

1456 = 6x + x
1456 = 7x
x = 28

28 discount tickets were sold. The total number of tickets sold is equal to both the number of discount tickets sold plus six times that number: 1,456 = 6x+ x. Solve for x. 

The circle is centered at (5, −7) and has a radius of 7.

Step-by-step explanation:

The standard form of the equation of a circle with center (a,b) and radius r is given as:

The given equation is

We rewrite to look like the stay form:

We now compare the two equations to get:

a=5, b=-7 and r=7.

Therefore the circle is centered at (5,-7) and has a radius of 7
