Since there are 2 length sides and 2 width sides, the best equation to represent the perimeter would be 2x + 2(10) = P
Answer:
B
Step-by-step explanation:
Answer:
D = {-2, 0}
Step-by-step explanation:
If the range is {-3, 1}, that means -3 and 1 are <em>images</em> of some points a, b in the domain. So, there are two points a, b in the domain such that:
g(a) = -3 and g(b) = 1
If g(a) = -3 then 2a + 1 = -3 ------>2a = -4 ------> a = -2
If g(b) = 1 then 2b + 1 = 1 ------> 2b = 0 ------> b = 0
Hence D = {-2, 0}
2/1 recipricol is when you exchange it or turn it around
Its C. He substituted incorrectly when calculating the constant of variation.
Reason: He said so
