If a system of two linear equations has no solutions, which of the following statements describes the graph of the two corresponding lines in the xy-plane?
a. The lines are coinciding
b. The lines intersect at only one point
c. The lines are parallel
d. The lines are perpendicular
Explain why you picked your answer:

Answers

3 because it is the best

From the linear equation, the option that describes the graph of the two corresponding lines is C. The lines are parallel.

Based on the complete information, it should be noted that the lines are not coinciding and they don't intersect at only one point.

Rather, it can be deduced that the graph of the two corresponding lines in the xy-plane are parallel.

................

In the accompanying diagram, transversal EF intersects parallel lines AB and CD at G and H, respectively. If m∠EGB = 2x + 40 and m∠FHC = 3x - 10, what is the value of x

Answers

No diagram is provided but we can still work it out (it may vary).

So the from the description, we can tell that m∠EGB = m∠FHC through alternate exterior angles.

So,

m∠EGB = 2x + 40

m∠FHC = 3x - 10

m∠EGB = m∠FHC

2x + 40 = 3x - 10

40 = 3x - 2x - 10

40 = x - 10

40 + 10 = x

50 = x

x = 50

The value of x is 50

The combined average weight of an okapi and a llama is 450 kilograms.

3 llamas, on average, weigh 190 kilograms more than an average okapi.

You want to find the average weight of each type of animal.

Answers

Answer:

An average Ilama weighs 160 kilograms and an average okapi weighs 290 kilograms.

Step-by-step explanation:

Let,

x be the average weight of a Ilamas

y be the average weight of an okapi

According to given statement;

x + y = 450     Eqn 1

3x = y + 190   Eqn 2

From Eqn 2

y = 3x - 190     Eqn 3

Putting this value of y in Eqn 1

x + (3x-190) = 450

x + 3x - 190 = 450

4x = 450 + 190

4x = 640

Dividing both sides by 4

[tex]\frac{4x}{4}=\frac{640}{4}\\x=160\\[/tex]

Putting x = 160 in Eqn 3

y = 3(160) - 190

y = 480 - 190

y = 290

Hence,

An average Ilama weighs 160 kilograms and an average okapi weighs 290 kilograms.

Abigail wants to ride her bicycle 30.4 miles this week. She has already ridden 7 miles.
If she rides for 3 more days, write and solve an equation which can be used to
determine m, the average number of miles she would have to ride each day to meet
her goal.

Answers

Answer:

3m + 7 = 30.4

m = 7.8

Step-by-step explanation:

3m, where m is the average number of miles per day, will represent how many miles she rides in the next 3 days.

She has already ridden 7 miles, so 7 has to be added to 3m in the equation.

Then, the equation has to be set equal to 30.4, because that is her goal for the week

Put this all together:

3m + 7 = 30.4

Solve for m:

3m + 7 = 30.4

3m = 23.4

m = 7.8

So, Abigail has to ride an average of 7.8 miles per day to meet her goal.

1.

1.365 x 10^3 = 1365

3.

479 x 10^(-1) = 4.79 * 10^1 = 47.9

479 x 10^(-2) = 4.79 * 10^0 = 4.79

Number of Similar Preferences Number of Married Couples
All four 30
Three 128
Two 124
One 61
None 32
Suppose that a married couple is selected at random.
(a) Use the data to estimate the probability that they will have 0, 1, 2, 3, or 4 personality preferences in common. (Enter your answers to 2 decimal places.)
0 1 2 3 4

i. Yes, because they do not cover the entire sample space.
ii. No, because they do not cover the entire sample space.

(c) What is the sample space in this problem?
i. 0, 1, 2, 3 personality preferences in common
ii. 1, 2, 3, 4 personality preferences in common
iii. 0, 1, 2, 3, 4, 5 personality preferences in common
iv. 0, 1, 2, 3, 4 personality preferences in common

Answers

Answer:

a. Probability (0) = 36/375 = 0.096

Probability (1) = 61/375 = 0.162

Probability (2) = 124/375 = 0.330

Probability (3) = 128/375 = 0.341

Probability (4) = 30/375  = 0.08  

b.  iii) Yes, because they cover the entire sample space.    

c. Obviously, the sample space in this problem is iv.

iv = {0,1,2,3,4}  personality preferences in common.    

Step-by-step explanation:

In this question, we are asked to calculated the probability of preferences in common.

As we know, the general formula for probability is:

Probability = Number of favorable outcome/ Total number of favorable outcomes

Data Given:

For 0 = 36

For 1 = 61

For 2 = 124

For 3 = 128

For 4 = 128

Total = 375 Married Couples

Probability (0) = Number of favorable outcomes/ Total Number of Favorable outcomes

Probability (0) = 36/375 = 0.096

Similarly,

Probability (1) = 61/375 = 0.162

Similarly,

Probability (2) = 124/375 = 0.330

Similarly,

Probability (3) = 128/375 = 0.341

Similarly,

Probability (4) = 30/375  = 0.08

b. Total Probability can never be greater than 1 and less than 0.

So,  Probabilities of the sample  will add up to 1

iii) Yes, because they cover the entire sample space.

Total Probability = P(0) + P(1) + P(2) + P(3) + P(4) = 1

Total Probability = 0.09 + 0.16 + 0.33 + 0.34 + 0.08 = 1

c. Obviously, the sample space in this problem is iv.

iv = {0,1,2,3,4}  personality preferences in common.

Are 4x, 4y, and 4xy like terms?

Answers

Answer: yes



Explanation:

In algebra, like terms are terms that have the same combination of variables raised to the same powers. Let's determine whether 4x, 4y, and 4xy are like terms.

The term 4x consists of the variable x raised to the power of 1, while the term 4y contains the variable y raised to the power of 1. Thus, both 4x and 4y have the same combination of variables raised to the same power. Therefore, they can be considered like terms. On the other hand, the term 4xy consists of both the variables x and y, each raised to the power of 1.

Although it includes both x and y, the arrangement of the variables is different from the previous terms. This means that 4xy is not a like term to either 4x or 4y. In conclusion, among the given terms, 4x and 4y are like terms, while 4xy is not. It is important to identify like terms in algebra to simplify expressions and combine similar terms for easier calculations.

Part B: Write one example of a linear function and one example of a non-linear function.. (Use x and y as the variables) (10 points)

Answers

Answer:

Part A:

The graph passes through (0,2) (1,3) (2,4).

If the graph that passes through these points represents a linear function, then the slope must be the same for any two given points. Using (0,2) and (1,3). Write in slope-intercept form, y=mx+b. y=x+2

Using (0,2) and (2,4). Write in slope-intercept form, y=mx+b. y=x+2. They are the same and in graph form, it gives us a straight line.

Since the slope is constant (the same) everywhere, the function is linear.

Part B:

A linear function is of the form y=mx+b where m is the slope and b is the y-intercept.

An example is  y=2x-3

A linear function can also be of the form ax+by=c where a, b and c are constants. An example is 2x + 4y= 3

*Product of x and y

*Trigonometric function

*Exponential functions

*Logarithmic functions

*A degree which is not equal to 1 or 0.
