Is the Port Townsend sales price ever double the Seattle sales price?

Mathematics

Using linear functions, it is found that the sales price in Port Townsend is never double the Seattle price.

A linear function has the following format:

y = mx + b

In which:

  • m is the slope, which is the rate of change.
  • b is the y-intercept, which is the initial value.

For Seattle:

  • Initial value of $38,000 in 1970, thus the y-intercept is b = 38000.
  • Increased by $137,000 in 20 years, thus the slope is:

m = \frac{137000}{20} = 6850

Thus, the <u>sales prince in n years after 1970</u> for Seattle is:

S(n) = 38000 + 6850n

For Port Townsend:

  • Initial value of $8,400 in 1970, thus the y-intercept is b = 8400.
  • Increased by $160,000 in 20 years, thus the slope is:

m = \frac{160000}{20} = 8000

Thus, the <u>sales prince in n years after 1970</u> for Port Townsend is:

P(n) = 8400 + 8000n

Port Townsend is double Seattle in n years after 1970, for which:

P(n) = 2S(n)

Then

8400 + 8000n = 2(38000 + 6850n)

8400 + 8000n = 76000 + 13700n

7500n = -67600

Negative number, and we are working only with positive, thus, it is found that the sales price in Port Townsend is never double the Seattle price.

9x - 4/x = 3. How to solve this? What is the value of x?
Ket [755]
9x-4/x=3 ok first lets get the like terms together! So 9x+1x=10x rewrite 10x-4=3 add 4 to both sides 10x=7 then divide 10 7/10=.7 x=.7
Or you can do it this way
9x-4/x=3 combine like terms so times -4 to both sides 3*-4=-12 rewrite 9x+x=-12 combine like term (still got some) 9x+1x=10x rewrite 10x=-12 divide 10 to both sides -12/10=-1.2 rewrite x=-1.2 (I'm like 95% sure it's this one) hope this helps!!! Have a nice nite (Don't be afraid to ask me about details on this or another question)!!!

Lisa started to drive from Boston to Washington, DC, which is 440 miles away, at 8:00 AM. For the first four hours of her trip,
sukhopar [10]

Answer:

60 mph

Step-by-step explanation:

Given;

Total distance covered d = 440 miles

Average speed in the first 4 hours v1 = 50 mph

Total time taken for the whole trip t = 8:00 to 4:00pm

t = 16:00-8:00 = 8 hours

Firstly we need to calculate the distance covered during the first 4 hours;

d1 = average speed × time = v1 × t1

t1 = 4

d1 = 50 × 4 = 200 miles

Then we need to calculate the distance covered in the second period of the journey;

d = d1 + d2

d2 = d - d1

Substituting the values;

d2 = 440 - 200

d2 = 240 miles

The time taken for the second period of travel t2;

t2 = t -t1 = 8-4

t2 = 4 hours

Average speed = distance travelled ÷ time taken

The average speed for the second part of the trip v2 is;

v2 = d2 ÷ t2

Substituting t2 and d2;

v2 = 240 miles ÷ 4 hours

v2 = 60 mph

The average speed during the second part of the trip is 60 mph
