Choice A is false because they are rounding to the nearest tenth (one decimal place) and not nearest hundredth (two decimal places)
Choice B is false as well because 3.825 should round to 3.83. The 5 at the end tells you to round up.
Choice C is false too. The value 3.824 should round to 3.82. Not sure how they got 3.81, so it seems like a deliberate trick question or silly answer.
Choice D is true. The three decimal values are rounded properly to the correct number of decimal places.
Therefore choice D is the answer
Answer:
Step-by-step explanation:
1) Distance covered by motorcycle = x
y = 50 + (x -2)*10
2)Distance traveled = 5 km
y = 50 + ( 5-2) *10
= 50 + 3*10
= 50 + 30
= 80
Seth will be paid Php 80
3) y = 120
50 + (x - 2)* 10 = y
50 + (x -2) *10 = 120
50 + 10x - 2*10 = 120
50 + 10x - 20 = 120
30 + 10x = 120
10x = 120 - 30
10x = 90
x = 90/10
x = 9
A passenger can travel 9 km.
4)y = (x - 2)*10
y = 10x - 20
20 + y = 10x
20 = 10x - y
10x - y = 20 {Ax + By = C form}
Hello,
f(x)=2x²+1
f(ax+b)=2(ax+b)²+1=2(a²x²+2abx+b²)+1=2a²x²+4abx+2b²+1
af(x)+b=a(2x²+1)+b=2ax²+a+b
And f(ax+b)≠af(x)+b not linear
The answer is D. 25
All that was need to be done was to divide
