</span><span>9x − 3(x+8) [distribute] = 9x − 3x − 24 = 6x − 24 [combine like terms]
</span>
<span>8(x−3)−2x = [distribute] 8x−24−2x = 6x−24 [combine like terms] </span>
We can round 68 to 70
And round 42 to 40
70 x 40 = 2800
Take 18 and divide it by 120. Your answer os 0.15
Answers:
(2) Option (B) 4
(3) The answer is: +1
Explanations:
(2) The plus sign in the limit indicates that it is the right hand limit. So we have to approach to 2 from the right side of the graph. When we do that, we see the value of y = +4. Hence the correct option is (B) 4
NOTE: Although the question seems complex because there is slope involved but in this particular case, the examiner is concerned about the right hand limit.
(3) The minus sign in the limit indicates that it is the left hand limit. So we have to approach to 3 from the left side of the graph. When we do that, we see the value of y = +1. Hence the correct answer is +1.
