where m is:
and where b is:

Answers

Answer:

y = -4x + 29

Step-by-step explanation:

-3 = -4(8) + b

-3 = -32+b

29=b

The equation whose slope is -4 and passes through (8,-3) is y=-4x+29 where slope is -4.

What is equation?

Equation is relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It is of many types like linear equation, quadratic equation, cubic equation, etc.

How to form equation?

We have been given slope of line being -4 and point through which it passes (8,-3) and we have to find the equation of line.

The equation from two points can be calculated through the following formula:

y-[tex]y_{1}[/tex]=m(x-[tex]x_{1}[/tex]) and slope is m.

Putting the values of points and slope in the formula given above.

y-(-3)=-4(x-8)

y+3=-4(x-8)

y+3=-4x+32

y=-4x+32-3

y=-4x+29

Hence the equation is y=-4x+29 where slope is -4.

Sarah earned 45 1/2 dollars in 5 3/4 minutes. What is the unit rate in dollars per
minute?

Answers

Answer:

7 21/23 dollars per minute

Step-by-step explanation:

Total amount Sarah earns = 45 1/2 dollars

Time taken to earn = 5 3/4 minutes

What is the unit rate in dollars per

minute?

unit rate in dollars per

minute = Total amount Sarah earns / Time taken to earn

= 45 1/2 ÷ 5 3/4

= 91/2 ÷ 23/4

= 91/2 × 4/23

= (91 * 4) / (2 * 23)

= 364/46

= 7 42/46

= 7 21/23 dollars per minute

unit rate in dollars per

Someone please help me with this I can’t fail this test !

Answers

i gotchu bro you ain’t getting this wrong

ITS D!!! h = -6 k = -30

The equation of a vertical parabola in vertex form is equal to

f(x)= a(xh)² + k

where

a is a coefficient

(h,k) is the vertex

we have

f)x) = x² + 12x + 6

Convert to vertex form

Complete the square

f)x) 6= x² + 12x

f)x) - 6+36= (x² + 12x +36)

f)x)+ 30 = (x² + 12x +36) -

f)x)+30= (x+6)²

f)x) = (x+6)² – 30. -----> equation in vertex form

therefore

The vertex is the point (-6,-30)

There were some adults and children at the party. For every 3 adults, there 11 children. There were 32 more children than adults. How many adults were at the party?

Answers

Answer:

12 adults

Step-by-step explanation:

Given that :

Let :

Number of children = x

Number of adult = y

x = 32 + y - - - - - (1)

Ratio of adult to children

3 : 11

x = (11/3)y - - - (2)

Put x = 11/3y in (1)

(11/3)y = 32 + y

11y/3 - y = 32

(11y - 3y) / 3 = 32

11y - 3y = 32 * 3

8y = 96

y = 96/8

y = 12

Hence, number of adults = 12

Wendy brought 4 cakes and 2 pies for $20. The cost of a cake is twice the cost of 1 pie. A) What was the cost of one cake b)What was the cost of 1 pie?

Answers

Answer:

a. The cost of one cake is $4.

b. The cost of one pie is $2.

Step-by-step explanation:

Let the cost of cake be C.Let the cost of pie be P

C = 2P  .....equation 1

4C + 2P = 20  .....equation 2

Substituting eqn 1 into eqn 2, we have;

4(2P) + 2P = 20

8P + 2P = 20

10P = 20

P = 20/10

Pie, P = $2

Next, we would determine the cost of a cake;

From equation 1;

C = 2P

Substituting the value of "P" we have;

C = 2 * 2

Cake, C = $4

Therefore, we would have the following answers;

a. The cost of one cake is $4.

b. The cost of one pie is $2.

Check:

From equation 2;

4C + 2P = 20

4(4) + 2(2) = 20

16 + 4 = 20

20 = 20

how do solve this problem

Answers

Answer:

vertically opposite angles are equal

3x+112°=5x+100°

112°-100°=5x-3x

12°=2x

12°÷2=2x÷2

6°=x

therefore x=6°

Step-by-step explanation:

hope this is helpful

Answer:

x = 6

Step-by-step explanation:

The 2 angles are vertically opposite and are congruent, so

5x + 100 = 3x + 112 ( subtract 3x from both sides )

2x + 100 = 112 ( subtract 100 from both sides )

2x = 12 ( divide both sides by 2 )

x = 6

A landscape-supply company sells mulch at a rate of $30 per cubic yard. What price does the company charge for 54 cubic feet of mulch? (1 yard = 3 feet.

$54
$60
$810
$1,620​

Answers

Answer:

$60

Step-by-step explanation:

The details given the in the question are;

The rate at which the landscape-supply company sells each cubic yard of mulch = $30 per cubic yard

The price the company charges for 54 cubic feet of mulch = Required

The factor for converting yard to feet is 1 yard = 3 feet

Therefore;

1 cubic yard = 1 yard × 1 yard × 1 yard = 3 feet × 3 feet × 3 feet = 27 cubic feet

∴ 2 cubic yard = 2 × 1 cubic yard = 2 × 27 cubic feet = 54 cubic feet

1 cubic yard = $30

∴ 2 cubic yard = 54 cubic feet = 2 × $30 = $60

This discipline eliminates the intake of meat and in some cases also the consumption of dairy products and eggs. Are there enough reasons to make you change your eating habits? My purpose is to prove that vegetarianism is the diet that offers more benefits to our health, spirit, and society.Nowadays, health is the number one individual and governmental concern. Health is a fragile factor and its behavior relies mostly on the nutritional quality of the food we ingest. A balanced non-vegetarian diet allows the consumption of all four main food groups including meat and other animal by-products that are important protein and fat sources. Most of us consume more proteins and fats than we need. An excess of proteins can cause kidney failure and/or osteoporosis, and a high-fat diet can eventually lead to heart disease, cancer, obesity, and diabetes. On the other hand, vegetarians get protein from grains, beans, vegetables, and low-fat food. This is how they reduce the risk of most diseases caused by fats. It is a myth to believe that vegetarians don't get enough proteins or that their diet is not balanced because they don't eat meat. The key isvariety and accurate combinations of energy and protein sources. If I were asked to describe a vegetarian, I would immediately mention they are very disciplined people. It has been proven that there exists a remarkable correlation between the people who succeed and people who follow a disciplined lifestyle. People who are faithful to the disciplines they have acquired show integrity, a remarkable behavior and they are usually in a good mood. Vegetarians, always concerned about quality and discipline, develop a greater social responsibility that motivates them to improve their environment.Moreover, environmental issues have been capturing public attention because of their relevancy and increasing deterioration of our quality of life. If you are concerned about the environment, consider that massive meat production can have a negative impact on tropical rain forests, soil stability, and air and water quality. Large extensions of forests have been cut and changed into grasslands that provide cattle with food. To conserve grasslands, fertilizers and other chemical substances are used; consequently, soil and water resources are polluted. Even though there are methods that avoid this kind of deterioration, producers prefer to ignore them so they can keep satisfying the increasing meat demand without affecting their production rates.Vegetarians' life spans are increased and through this discipline they learn to live quality life in all the possible aspects. Besides, their beliefs are congruent with their lifestyle and they take responsibility and action for problems within their own bodies and in their surroundings. Take a look at yourself. Is your health at risk? Have you been able to reach your goals? Are you a factor of change and improvement within your society? You must at least try becoming a vegetarian now that you know it is a tempting challenge and an exciting experiment that has advantages and no risks. Do it for your body, for your lifestyle, or for your environment, but do it. Stop letting others have all the credit, the fun, and the quality.1.
