Answer:
The anwser you are looking for is number 2
Step-by-step explanation:
Given your answer is say x<3, "x is less than 3", that means that 3 is not included in your solution set. The interval (-∞, 3); note the use of parenthesis. If the interval is [-3,6), this means that in your solution 3 is included but not 6. That is to say, 3≤x<6. [3,6]; both are included. (3,6) none is included.
Answer:
2 numbers could be 10 and 12
or - 12 and - 10
Step-by-step explanation:
let the 2 numbers be x and x + 2
since they are 2 consecutive even numbers, the difference between them is 2
the difference between the reciprocals is 1/60
we have to mulitply the 2 denominators x and (x+2) to get a common denominator for the 2 fractions
=
we can then remove the brackets from the numerator and denominator
and then cross multiply
60 * 2 = x² + 2x
120 = x² + 2x
x² + 2x - 120 = 0
we have a quadratic equation which needs to be solved
x² + 12x - 10x - 120 = 0
x (x + 12) - 10(x + 12) = 0
(x - 10) (x + 12) = 0
x - 10 = 0 or x + 12 = 0
x = 10 x = -12
