Y varies inversely with x. When x = 3 then y = 5. Write a function to represent this relationship.

Mariulka [41]

Answer:

<em>The function to represent this relationship will be: $y= \frac{15}{x}$ </em>

Step-by-step explanation:

$y$ varies inversely with $x$ . That means......

$y= \frac{k}{x}..............................(1)$

where $k$ is a proportional constant.

Given that, when $x=3$ , then $y=5$

Plugging these values into the above equation, we will get.....

$5=\frac{k}{3}\\ \\ 5(3)=\frac{k}{3}(3)\\ \\ 15=k$

Now plugging this $k=15$ into equation (1).....

$y= \frac{15}{x}$

So, the function to represent this relationship will be: $y= \frac{15}{x}$

Water freezes at 0° Celsius. The table shows five different temperatures in degrees Celsius. Indicate whether each temperature i

KATRIN_1 [288]

0.5 is above because that .5 of a change is keeping the water from freezing because it is still slightly babouche freezing point.

-13 is below because the number is a negative so is below 0 anyway and is below the freezing point.

100 is above because the number 100 is higher than 0 so it’s above freezing point.

5.5 is above because it is a larger number than the freezing point so the water would not freeze yet at this temperature.

-2.25 is below because it’s a negative number.

I think that’s what you meant not 100% sure but that’s how I would do it :)

Solving a word problem using a two-step med

stepladder [879]

Inequality is 6t ≤ 44 and Jim can rent a boat for 7.33 hrs or less

<u> Solution:</u>

Given that

Maximum amount Jim can spend to rent a boat = $34

Rental cost of boat for 1 hour = $6

Also Jim has a discount coupon for $8 off.

Need to determine possible number of hours Jim could rent a boat.

Let’s assume possible number of hours Jim could rent a boat be represented by variable "t"

Cost of renting boat for 1 hour = 6

So Cost of renting a boat for t hours = t x renting boat for 1 hour = t x 6 = 6t

Also Maximum amount Jim can spend to rent a boat = $34

As Jim has a discount coupon for $8 off, so Total amount Jim can spend to rent a boat = $ 34 + $ 8 = $ 44

So cost of renting a boat for t hours must be less that of equal to Total amount Jim can spend to rent a boat

=> 6t ≤ 44

On solving above equality for "t" we get ,

$\begin{array}{l}{t \leq \frac{44}{6}} \\\\ {=>\mathrm{t} \leq 7.3333 \mathrm{hrs}}\end{array}$

Hence inequality is 6t ≤ 44 and Jim can rent a boat for 7.33 hrs or less.
