Suppose there are two types of tickets to a show: advance and same day. The combined cost of one advance ticket and one same day
Debora [2.8K]

Answer:

Answer = $30.00 advanced and $36.00 same day.

Step-by-step explanation: We can replace 20:40 ratio.

30 x 20 and 70 x 20 = 600+ 800 =3/5  to find 2/4 = 12/20 finds 10/20 through HCF and hereafter we have one ticket is 1/6 more. So if 60 tickets were sold for 2000 then $33.33 would be the average and if one was 1/6 more than the other it is 0.5/6 higher than 33.33 =2.66 more = £36 for All day and £30 for Advanced tickets. 36 x 20 = $600  and 36 x 40 =$1400. We know its $30 as we can double check its ratio after. 20:40 is 1/2 but then take off $3 each side to balance back to find $60 combined. $2000=1400+$600 =1:2 and 2:4 ratio.

What is the graph of the function f(x) = the quantity of x squared plus 4 x minus 12, all over x plus 6?
LenaWriter [7]
X^2 + 4x -12 = (x+6)(x-2)

so 
  (x+6)(x-2)
---------------- = x - 2
     x + 6

f(x) = x -2

answer is B.

because
if x = -6
then y = -6 - 2 = -8

(-6,-8) is the order pair

A circle has center
Fed [463]
Note that the equation of the circle is

(x-h)² +(y-k)² =r²

where centre is (h,k)

the equation of the circle based on the information given

(x-3)² +(y-4)² =r²
and the point on the circle (3,-2)

substitute into the equation

(3-3)² +(-2-4)² =r²

r=6 or r=-6

since r is radius, we reject r=-6 since radius must be nonnegative.

the radius is 6
