Answer: All x-coordinates are different, so this relation is a function.

Having the same y value more than once is not a problem for a function.

"This (does not/does) represents a function because different (x values/y values) can have the same (x values/y values)."

What is Y-3x=-2 and Y+x=-6
love history [14]
Rearranging the first equation gives:

y=3x-2

Substituting this into the other equation gives:

y+x=-6&#10;\\(3x-2)+x=-6&#10;\\4x-2=-6&#10;\\4x=-4 \\x=-1

If x=-1:

y+(-1)=-6&#10;\\y=-5

So x=-1, y=-5

In 1992, the countries Chad and Denmark each had population of about 5.2 million. However,
irinina [24]

9514 1404 393

Answer:

  5,339,479

Step-by-step explanation:

The populations in millions of the different countries can be represented by the equations ...

  c = 5.2(1.025^t)

  d = 5.2(1.001^t)

We want to find d when c = 10. Solving for t when c=10, we have ...

  10 = 5.2(1.025^t)

  10/5.2 = 1.025^t

  log(10/5.2) = t×log(1.025)

  t = log(10/5.2)/log(1.025)

Then the value of d for that value of t is ...

  d = 5.2(1.001^(log(10/5.2)/log(1.025)) ≈ 5.3394789

The population of Denmark is about 5,339,479 when the population of Chad is 10 million.

_____

If we round the number of years to 26.5 before computing the population of Denmark, we get 5,339,571 -- about 92 more people. Ordinarily, one would not round intermediate results.

The length of a photograph of Mr. Lemley playing golf is 1475 inches. If the area
Mice21 [21]

Answer:

1.12 × 10^-3

Step-by-step explanation:

The computation of the width of the photograph is as follows:

As we know that

Area of the rectangle = length × width

33 ÷ 20 square inches = 1475 inches × width

So, the width is

= Length ÷ area

=  1475 inches ÷ (33 ÷ 20 square inches)

= 1.12 × 10^-3
