Answer:

The equation of line p is y = -³/₂x + 3

Step-by-step explanation:

Let's first find the slope of the line. That's equal to Δy/Δx:

(-3 - 6) / (4 - (-2))

= -9 / 6

= -3/2

With that, we can plug it in to the format:

Δy = sΔx, or (y - y1) = s(x - x1):

y - 6 = s(x - (-2))

y - 6 = (-3/2)(x + 2)

y = -3x / 2 - 3 + 6

y = -³/₂x + 3

A roofing contractor buys 30 bundles of shingles and 4

rolls of roofing paper for $1040.

In a second purchase (at the same prices), the

contractor buys 12 bundles of shingles and 16 rolls of

roofing paper for $2000.

Create and solve a system of equations in order to

determine how much each bundle of shingles (x) and

roll of roofing paper (y) would cost

Answers

Answer:

Cost of one bundle of shingles is $20 and cost of one roll of roofing paper is $110.

Step-by-step explanation:

Let the cost of each bundle of shingles = x

And cost of the roofing paper = y

Contractor buys 30 bundles of shingles and 4 rolls of roofing paper for $1040.

30x + 4y = 1040

15x + 2y = 520 -----(1)

In a second purchase contractor buys 12 bundles of shingles and 16 rolls of roofing paper for $2000

12x + 16y = 2000

3x + 4y = 500 --- (2)

Equation (1) multiplied by 2 then subtracted from equation (2)

(3x + 4y) - 2(15x + 2y) = 500 - 1040

(3x - 30x) + (4y - 4y) = -540

-27x = -540

x = 20

From equation (1)

15(20) + 2y = 520

300 + 2y = 520

2y = 220

y = 110

Therefore, cost of one bundle of shingles is $20 and cost of one roll of roofing paper is $110.

1. Delia brushes her teeth 6 hour
each day.
Units of Time
1 week = 7 days
1 hour = 60 minutes
Write and solve an equation to find
how many minutes Delia brushes
her teeth in 1 day. Then use that to
find the number of minutes she
brushes her teeth in 1 week.

Answers

Answer:

Answer:

PART A: 28 hours, PART B: 16800 minutes

Step-by-step explanation:

Delia Brushes her teeth = 1/6 hour

PART A

Total Week= 1 week

Total number of days in a week= 7 days

Total number of hours in a day= 24 hours

Total number of hours in a week= 24× 7 hours

Total number of hours in a week= 168 hours

Number of hours that Delia brushes her teeth = × 168 hours

Number of hours that Delia brushes her teeth = 28 hours

Hence, the correct answer is 28 hours

PART B

Total number of days in a week= 7 days

Total number of hours in a week= 168 hours

Total number of minutes in a week= 168 × 60

Total number of hours in a week= 100800 Minutes

Number of minutes that Delia brushes her teeth = × 100800

Number of hours that Delia brushes her teeth = 16800 minutes

Hence, the correct answer is 16800 minutes

You are at a coffee shop and notice that as the temperature of the room gets colder, more people order hot beverages. From this observation, you conclude that there is a _______ between the temperature and hot beverage sales at this coffee shop. Group of answer choices negative relationship curvilinear relationship no relationship positive relationship

Answers

Answer:

negative relationship.

Step-by-step explanation:

An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).

This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.

Cause and effect can be defined as the relationship between two things or events in which an occurrence one (cause) leads to the occurrence of another (effect).

A negative relationship or correlation can be defined as the relationship between two variables in which there exist an inverse relationship between them i.e as one variable increases, the other decreases and vice-versa.

In this scenario, you are at a coffee shop and notice that as the temperature of the room gets colder, more people order hot beverages. From this observation, you conclude that there is a negative relationship between the temperature and hot beverage sales at this coffee shop because for the temperature to get colder it would decrease and for the hot beverages to be hot, its temperature must be increased.
