The answer is as follows:
1/5
0.35
12/25
0.5
4/5

Just for a bit of explanation, 1/5 is equal to 0.2, 12/25 is just barely under 0.5, 4/5 is equal to 0.8.
I hope this helps!

One way is to make them all decimals or all fractions:

.5   .2  .35  .48  .80  are the numbers above changed to decimals.
I will make them the same length (two digit past the decimal point) to compare
.50   .20  .35  .48 and .80

Now it is easy to put them in order

.2  .35  .48   .5  and .80

Let's put them into all fractions

5/10   1/5   35/100   12/25 and 4/5

Instead of finding a common denominator let's try this:
Think of them as test scores - the person who got 1 out 5 did the worst
Next came the person who got only 35 out of 100 - they only did better than the one above (1/5)
12/25 is almost 1/2 but a little below half the questions right
5/10 is exactly half the questions right (so it is bigger than 12/25 by a little).
4/5 is the best score (and the only one who passed).
So 1/5, 35/100, 12/25, .5 and 4/5 are in order least to greatest and match the answer above in bold.

What is the range of f(x) = 3/4x -4
shusha [124]

Answer:

The range is the resulting y-values we get after substituting all the possible x-values.

For the given function : f(x) = \frac{3}{4x} -4

<u>See the attached figure.</u>

The zeros of the denominator at x = 0

The domain is: (-∞,0)∪(0,∞)

<u>The range</u> of the function is the domain of the inverse function of f(x)

y = 3/(4x) - 4

y + 4 = 3/(4x)

4x = 3/(y+4)

x=\frac{3}{4(y+4)}

The zeros of the inverse function:

4(y+4) = 0

y + 4 = 0

y = -4

∴ The range is (-∞,-4)∪(-4,∞)

So, the answer is {y | y > –4} ∪ {y | y < – 4}

=========================================

<u>Note</u>: If the given function is : f(x) = \frac{3}{4} x-4

It will be first degree polynomial function.

Both of the domain and the range = all real numbers R

25. Jen ran x miles last week and 18 miles
klasskru [66]

Answer:

Step-by-step explanation:

If Jen ran 34 miles over the last 2 weeks and only 18 miles the second week, she would've had to have run 16 miles the first week.

34= 18+x

I hope this helps!
