=1.585 + 2 + 2.322
=5.907
~8)
(3÷2÷5)
=1.585 - 1 - 2.322
=-1.737
9)3log7(2) -2log7(3) + 4log7(3) -2log7(2)
=0.356+2(0.565)
=1.486
9)x(x+2)=8
x=2
10)x/(2x+3)=1/9
9x=2x+3
x=3/7

Hope this helps

42 is the answer

Explanation:
50% of 80 is half of 80 which is 40

Then you would add 40 with 5% of 40

What you would do then is 5% times 40 then you would change the 5% into a decimal which is 0.05 and multiply it by 40 , which would get u 2

Then you would add the price with tax
40+2 = 42

H = {(2, 5), (3, 5), (4, 5), (5, 5), (6, 5)} Is H a function and why?.
mixer [17]

Answer:

Yes, each x-value has a unique y-value.

Step-by-step explanation:

This is a function because each x-value has its own y-value. If this is not the case then it is not a function, because then, two points with the same x-value and different y-values would fail the VLT.

Your graph does not have overlaps and each x-value has a unique y-value

VLT

The vertical line test (VLT) is a <u>simple method that mathematicians made because</u><u> they were lazy</u><u> to make a table of values and find duplicates. </u>

<u />

  • Passing the VLT means that if you drew a vertical line anywhere on the graph, it would only go through one point.
  • Failing the VLT would mean that the vertical line

A quick way to check if it is a function is by looking for duplicates of x-values and check that the duplicates have the same y-value.
