9r
Explanation:
4r + 9r = 13r
13r-11r = 2r
2r + 7r = 9r
Answer:
y = 
Step-by-step explanation:
Given
5x - 8y = 11 ( subtract 5x from both sides )
- 8y = 11 - 5x ( multiply through by - 1 )
8y = - 11 + 5x = 5x - 11 ( divide both sides by 8 )
y = 
Yes it is linear since it's in the standard form Ax+By = C
A = 2
B = -8
C = 16
Answer: D or #4: None of the above
Step-by-step explanation: Since the longest angle is 13 x has to be around half because its a 47 degree angle if we round it would be 6 so D
