D! if it’s 48 then the other side is 48 degrees, add that and it becomes 96. then subtract 180-96 and you get 84 <3
Answer:
child tickets: 115
adult tickets: 175
Step-by-step explanation:
number of child tickets = x
number of adult tickets = y
(value of child ticket [8] * number of child tickets [x]) + (value of adult ticket [8.5] * number of adult ticket [y]) = total value (2407.50)
8x + 8.5y= 2407.50
290 (total number of tickets) = x (number of child tickets) + y (number of adult tickets)
290 = x+y
system of equations: 8x + 8.5y= 2407.50
290 = x + y
solve equation:
x = 115
y = 175
Answer:
y =
x
Step-by-step explanation:
The equation of a line passing through the origin (0, 0 ) is
y = mx ( where m is the slope )
m =
=
, thus
y =
x
In the image below, I showed my work. What you basically do is find the greatest perfect square in each variable and you pull it out of the radical.
Checking, it all looks ok except for the range in number 7.
3 is a line with a slope so all reals (which you've written negative infinity to infinity, fine) make up both the domain and range.
4 is a parabola in the usual orientation, so a domain of all reals. There's a minimum so a range of y >= -1.
