Answer:

y - 7 = (1/10)(x - 5)

Step-by-step explanation:

Next time please share the possible answers.  Thank you.

Any line perpendicular to y = -10x + 1 has the slope +1/10, which is the negative reciprocal of -10.

Using the point-slope formula, we get:

Answer:

Question 1:

  • 2. Households that possess only cellphones.
  • 5. Households without telephones.

As the pollster used the telephone directory, they will get the numbers of listed people in that community. Cellphones are not listed along with households with telephones so these will be underrepresented.

Question 2:

  • 1. Lower income people (cannot afford a phone).
  • 2. people who choose not to list their numbers people who choose not to have phones.

Question 3:

  • 2. Households with unlisted numbers  
  • 4. Households with land-line telephones that have moved into the community since the most recent community telephone directory was printed.

Households with unlisted numbers will still be called because the person is using random dialling which means that even if the number is not listed, it can still be called. Households with landlines will most definitely be reachable as well.

2x+3y=15<br> x+y=6<br> work out the values of x and y
Anna [14]

Answer:

x=3

y=3

Step-by-step explanation:

x = 6-y

-plug in (6-y) into first equation

2(6-y)+3y = 15

12-2y+3y=15

-2y+3y = 3

y=3

x=6-3

x=3

(2*3) + (3*3) = 6 + 9 = 15
