Answer:
(x,y)→(y,-x)
Step-by-step explanation:
Parallelogram ABCD:
A(2,5)
B(5,4)
C(5,2)
D(2,3)
Parallelogram A'B'C'D':
A'(5,-4)
B'(4,-5)
C'(2,-5)
D'(3,-2)
Rule:
A(2,5)→A'(5,-2)
B(5,4)→B'(4,-5)
C(5,2)→C'(2,-5)
D(2,3)→D'(3,-2)
so the rule is
(x,y)→(y,-x)
Answer:
adult tickets
Step-by-step explanation:
Let x be the total sold adult ticket.
Given:
Total 582 tickets were sold.
There were 68 fewer student tickets sold than adult tickets
Then there were
students.
So, The total sold ticket equation is





Therefore, 257 adult tickets were sold
3y = 2x + 6
x + y = 7
y = 7 - x
3(7 - x) = 2x + 6
21 - 3x = 2x + 6
21 - 6 = 2x + 3x
15 = 5x
15/5 = x
3 = x
x + y = 7
3 + y = 7
y = 7 - 3
y = 4
Solution is (3,4)
Answer: 10 inches.
Step-by-step explanation:
Since the pecan pie is a circle, you can use this formula:

Where "r" is the radius and
is the central angle of the arc in radians.
If the pecan pie has been cut into 8 equal pieces then the central angle is:

Now you know the arc length and the central angle, then, you can solve for "r" from
:

Substituting values, you get that the radius of the pecan pie rounded to the nearest whole number is:
