The answer to this equation will be 2.
Answer:
(1) x^2 is greater than 1.
(2) x is greater than -1.
(1) x^2 is greater than 1 --> x2>1x2>1 --> x<−1x<−1 or x>1x>1. Sufficient.
(2) x is greater than -1 --> x>−1x>−1. Not sufficient.
Answer:
slope : 1/15
Step-by-step explanation:
slope = change in y / change in x
change in y = 1 / change in x = 15
therefore, 1/15 = slope
