Which of the following represent the rule y = x + 2?

Answer: speed (s) = distance (d) divided by time (t)

Step-by-step explanation: You can see that every 30 minutes or 0.5 hours, the ship's distance increases by 12.5 miles. The problem even say the ship's speed is constant...so it doesn't matter which numbers you use for your calculation just used the time with the corresponding distance.

Answer: all statements are true.

Step-to-step explanation:

Given: Cost of 1 box of cereal =$2.79

Cost of x boxes of cereal= $2.79 x

Each gallon of milk costs $4.49.

Hank bought 3 more boxes of cereal than gallons of milk.

gallons of milk = x-3

Total cost = (cost per box of cereal) × (x) +(Cost per gallon of milk) × (x-3)

= 2.79x + 4.49 (x-3)

All statements are correct:

A. The term x- 3 represents the number of gallons of milk.

B. The coefficient 2.79 represents the cost of one box of cereal.

C. The expression represents the total number of boxes of cereal and gallons of milk.

Answer:

(c) y = 2x - 5

Step-by-step explanation:

y=2x+y=5

subtract 2x from both sides of the equation

the answer is C

Big Phone Company offers a better deal for this call.

Option C is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Big Phone Company:

Cost after 4 minutes.

= 0.39 + 4 x 0.03

= 0.39 + 0.12

= $0.51

LittlePhone Company

Cost after 4 minutes.

= 0.25 + 4 x 0.07

= 0.25 + 0.28

= $0.53

Thus,

The Big Phone Company charges less as compared to the LittlePhone Company after using it for 4 minutes.

Answer:

y = 1 3 x + 13 3

Step-by-step explanation:

The equation of the line is  

y = 1 3 x + 13 3

. To find other points on the line, simply plug in an x value, and solve for the corresponding y value.

Explanation:

To find other points on the line, we first have to find the equation for the line. We can easily use point-slope form:  

y − y 1 = m ( x − x 1 )

y − 5 = 1 3 ( x 2 )

To put it in slope-intercept form, isolate y and simplify:

y= 1 3 ( x − 2 ) + 5

y = 1 3 x − 23 + 5

y = 1 3 x + 13 3

Answer:

u = -24/7

Step-by-step explanation:

u = 6 = u

v      -7     4

-7u = 24

u = -24/7

Answer:

u = - [tex]\frac{24}{7}[/tex]

Step-by-step explanation:

Given that u varies directly with v then the equation relating them is

u = kv ← k is the constant of variation

To find k use the condition u = 6 when v = - 7, then

6 = - 7k ( divide both sides by - 7 )

- [tex]\frac{6}{7}[/tex] = k

u = - [tex]\frac{6}{7}[/tex] v ← equation of variation

When v = 4 , then

u = - [tex]\frac{6}{7}[/tex] × 4 = - [tex]\frac{24}{7}[/tex]

Answer:

you will get the same answer its just that one equation is the other way around

Step-by-step explanation:

Each rectangle can be divided into 10 parts.

A fraction is a part of a whole quantity.

In a fraction, the denominator represents the number of equal parts in a whole, and the numerator represents how many parts are being considered.

Given,

Same size rectangles are cut into same number of equal parts.

Shaded part on one rectangle = 2/5

Shaded part on other rectangle = 1/2

Denominator shows total parts of whole,

To get the same number of equal parts, we need to find

Least common multiple of the denominator

= 2 × 5 = 10

Hence, Into 10 parts, each rectangle should be divided.

Answer:

Pumpkins pounds and weight

Step-by-step explanation:

Answer: Percy decided to weigh different numbers of pumpkins to find their weights. He put his findings in the table above (in he question) . He found a pattern in his findings, so he used it to find how many 50 pumpkins will weigh. Can you tell me what answer he got?

Step-by-step explanation:

Since every 5 pumpkins is 8 pounds, we just need to divide 50 by 5, and times that number by 8 pounds to find the answer.

50/5 is 10.

10 x 8 = 80

Or, since 25 are 50 pounds, and 25 +25 = 50, you ad 40 to 40, giving you the answer 80.

The answer to my word problem is 80.

Step-by-step explanation:

Answer:

1a) 67.2 kg

1b) 66.5 kg

1c) 64 kg, 68 kg

2a) Mean = 58.1m, Median = 55m, Mode = 49m

2b) The mode is not a good measure since all data except 49m appeared twice i.e. the data set is quite distributed. (sorry I am not very sure with this answer)

3a) Independent variable is time, Dependent variable is distance.

3b) See attachment.

3c) Linear

3d) 2.5s: 10m 6.25s: 25m 8s: 32m

3e) 3m: 0.75s 21m: 5.25s. 36m: 9s.

Step-by-step explanation:

1a) Mean = (74+71+68+84+54+60+64+68+65+64)/10 kg = 67.2 kg

1b) Sort the data in ascending order (in kg).

54 60 64 64 65 68 68 71 74 84

Median = (65+68)/2 kg = 66.5 kg

1c) Mode = 64 kg, 68 kg (both appeared twice)

2a) Mean = (45+52+47+55+62+80+71+60+84+57+46+50+48+61+49+63+54+49+72)/19 m =  58.1m (correct to 1 decimal place)

Arrange the data in ascending order (in m).

45 46 47 48 49 49 50 52 54 55 57 60 61 62 63 71 72 80 84

Median = 55m

Mode = 49m (appeared twice)

2b) See answer.

3a) Independent variable is the variable that is to be changed. Dependent variable is the variable that is to be measured.

3b) Just plot the graph.

3c) Distance = 4 x time

3d) 2.5 x 4 = 10m. 6.25 x 4 = 25m. 8 x 4 = 32m.

3e) 3/4=0.75s. 21/4=5.25s. 36/4=9s.

In II quadrant, only [tex]\sin \theta, \text{cosec}\theta[/tex] are positive and others are negative.

In III quadrant, only [tex]\cot \theta, \tan\theta[/tex] are positive and others are negative.

In IV quadrant, only [tex]\cos \theta, \sec\theta[/tex] are positive and others are negative.

We have,

[tex]\tan \theta > 0[/tex] and [tex]\sec \theta <0[/tex].

x=10/7

Let's solve your equation step-by-step

6x−1=−x+9

Step 1: Add x to both sides

6x−1+x=−x+9+x

7x−1=9

Step 2: Add 1 to both sides

7x−1+1=9+1

7x=10

Step 3: Divide both sides by 7

7x/7=10/7

x=10/7

Answer:

x = 10 / 7

Step-by-step explanation:

6x - 1 = -x + 9

Add 1 to both sides of the equation.

6x - 1 = -x + 9

6x - 1 + 1 = -x + 9 + 1

Simplify

Add the numbers

6x - 1 + 1 = -x + 9 + 1

6x = -x + 9 + 1

Add the numbers

6x = -x + 9 + 1

6x = -x + 10

Add x to both sides of the equation.

6x = -x + 10

6x + x = -x + 10 + x

Simplify

Combine like terms

6x + x = -x + 10 + x

7x = -x + 10 + x

Combine like terms

7x = -x + 10 + x

7x = 10

Divide both sides of the equation by the same term

7x = 10

7x/7 = 10/7

Simplify

Cancel terms that are in both the numerator and denominator.

7x/7 = 10/7

x = 10/7

Solution

x = 10/7

The different measuring instruments to be used in the economic/business system of the new civilization is discussed below in detail.

Step-by-step explanation:

Economics is the research of how people allocate limited resources for generation, circulation, and consumption, both personally and collectively.

Two significant types of economics are microeconomics, which concentrates on the performance of individual customers and generators, and macroeconomics, which measures overall economies on a local, nationwide, or global scale.

Economics is especially concerned with performance in generation and exchange and practices models and opinions to assume how to generate incentives and procedures that will maximize productivity.

Economists formulate and announce numerous economic symbols, such as the Consumer Price Index (CPI). and gross domestic product (GDP).

Capitalism, communism, and socialism are examples of economic systems.
