Answer:
The answer is C
Step-by-step explanation: because it is reflecting and is backwards.
Answer:
D. (-5,2)
Step-by-step explanation:
1st reflection = reflection across the line k with the rule:
(x,y)→(-y,-x)
So,
(2,5)→(-5,-2)
2nd reflection = reflection across the x-axis with the rule
(x,y)→(x,-y)
So,
(-5,-2)→(-5,2)
After two consecutive reflections
(2,5)→(5,2)
A + c = 158......a = 158 - c
9.90a + 5.50c = 1265
9.90(158 - c) + 5.50c = 1265
1564.20 - 9.90c + 5.50c = 1265
- 4.40c = 1265 - 1564.20
-4.40c = - 299.20
c = -299.20/-4.40
c = 68 <=== 68 child tickets sold
Step-by-step explanation:
step 1. a polynomial must have whole non negative exponents
step 2. A, B, D have negative exponents
step 3. C is a polynomial.
