We need to find distance they travel as a function of time. This simply means that x is the function of time. The destination is 120 miles away, this is irrelevant for the question that is currently being asked. However, we know that they have already travelled 20 miles and are going 50 miles and hour. So lets plug in what we have.

50 is our rate of change, so we match that with the x.

20 is our constant, the distance already travelled.

This means our function is:

f(x) = 50x + 20

This means our answer is D) f(x) = 50x + 20

Lets also plug in 120 to solve how much further they need to travel before arriving.

120 is our f(x) as it is the final distance travelled.

120 = 50x + 20

120-20 = 50x

100 = 50x

100/50 = x

2 = x

This means that they need to travel 2 hours in addition to the 20 miles they have already gone.

I hope I've helped! :)

snow_tiger [21]

Answer: The price of Zoe's dinner before sales tax and tips is $13.96.

Step-by-step explanation:

Since we have given that

Amount Zoe paid after sales tax and tip = $18.60

Let the price before tax be 'x'.

Rate of sales tax = 11%

So, it becomes,

\frac{11}{100}\times x\\\\=0.11x

So, Amount after tax, our equation, becomes,

x+0.11x=\$18.60\\\\1.11x=\$18.60\\\\x=\frac{18.60}{1.11}\\\\x=\$16.75

Now, let the amount before tips be 'y'.

Rate of tips = 20%

So, it becomes,

\frac{20}{100}\times y\\\\=0.2y

So, After tips it becomes,

y+0.2y=\$16.75\\\\1.2y=\$16.75\\\\y=\frac{16.75}{1.2}\\\\y=\$13.96

Hence, The price of Zoe's dinner before sales tax and tips is $13.96.

Determine the area<br> i don't know the answer
mamaluj [8]

The answer is 48m² because 48 times 2 is 96. Not 96m² because that would be 96 times 2 And wayyy too much. You do 6 times four which is 24 then 24 times four because it is separated into four quadrants & that would equal 96m & half of 96 is 48
