The equation of a straight line is given by:

y = mx + c

where m is the slope and c is the y-intercept.

From the given graph, the y-intercept is 1.

The slope of a straight line is given by:

[tex]m= \frac{y_2-y_1}{x_2-x_1} [/tex]

Where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points on the line.

From the graph, (0, 1) and (14, 8) are two points on the line, thus:

[tex]m= \frac{8-1}{14-0} = \frac{7}{14} = \frac{1}{2} [/tex]

Therefore, the equation representing the graph is [tex]y= \frac{1}{2} x+1[/tex]

If Jill is playing a game with a single die (singular form of dice), what are the chances she would throw any one number twice in a row?

Answers

The answer would be 1/6.

A common mistake made on problems like these is to say the answer is 1/12.


The only roll that really matters in this problem is the second one. This is because the first role only determines what the second role must be. Therefore, you only take the probability of rolling one fixed number in one roll, which would be one in six.

I appreciate the fact that you said die in your question, instead of dice.

Help I do not understand how to find the area of circles

Answers

The formula for the area of a circle is a = πr², r being the radius.

To tackle this problem, find the area of the square and then subtract the area if the circle:

Area of square = 20 * 20 = 400
Area of circle = π(10)² = 100π = 314

Area of square - area of circle = 400 - 314 = 86 m²

solve the system of equation-5x+2y=9 y=7x

Answers

x = 2y/5 - 9/5
y = 5x/2 + 9/2
(I don't know if this is correct)
Hope this helps!

The system of equations -5x + 2y = 9 and y = 7x is solved using substitution, yielding the solution x = 1 and y = 7.

To solve the system of equations -5x + 2y = 9 and y = 7x, we can use substitution since the second equation gives us 'y' in terms of 'x' directly. We substitute 7x in for y in the first equation:

-5x + 2(7x) = 9

-5x + 14x = 9

9x = 9

x = 1

Now that we have the value for x, we can find y using the second equation:

y = 7(1)

y = 7

Therefore, the solution to the system of equations is x = 1 and y = 7.

Solve using distributive property 6 x 4.4

Answers

Final answer:

To solve the equation 6 x 4.4 with the distributive property, multiply 6 by each part of 4.4 (which is divided into 4 and 0.4) separately and then add the results together. This yields 24 + 2.4, which equals 26.4.

Explanation:

To solve the multiplication problem 6 x 4.4 using the distributive property, we can break down the number 4.4 into 4 and 0.4. Then we distribute the multiplication over these two addends separately.

This can be written as:

6 x (4 + 0.4) = (6 x 4) + (6 x 0.4)

Next, we solve each part of the equation:

6 x 4 = 24

6 x 0.4 = 2.4

Finally, we combine these two results to get the final answer:

24 + 2.4 = 26.4

Thus, 6 multiplied by 4.4 equals 26.4.

Find the value of x and AB if B is between A and C, AB = 2x, AC = 6x - 5 , BC = 7

Answers

We have AB + BC = AC.

2x + 7 = 6x - 5

2x - 6x = - 5 - 7

-4x = -12

x = -12/-4

x = 3

We both know that x is 3.

We also want AB.

AB = 2x

AB = 2(3)

AB = 6

Did you follow?
Final answer:

The problem deals with the segment addition postulate. By setting up and solving the relevant equation (2x + 7 = 6x - 5), we find that x = 3. Therefore, the length of AB = 6.

Explanation:

The subject of this question is segment addition postulate in mathematics. Given that B is between A and C, it implies that AB + BC = AC. From the problem, it's given that AB = 2x, AC = 6x - 5 and BC = 7. Setting up the equation would yield 2x + 7 = 6x - 5. Solving this equation gives us x = 3. Therefore, by substituting x=3 in AB = 2x we find that AB = 6.

The table shows five transactions and the resulting account balance in a bank account, except some numbers are missing. Fill the missing numbers

Answers

Answer:

transaction 3 (account balance) = 143

transaction 4 (account balance) = -86

transaction 5 (transaction amount) = 86

Step-by-step explanation:

From the table it is seen that after transactions the account balance either increases or decreases.

Transaction 1

transaction amount was 200 while account balance became 200

Transaction 2

the initial startup balance will be = transaction amount + current account balance  which is = 147 + 53 = 200 .

Note: the account balance of the previous transaction becomes the initial account balance of the next transaction

Transaction 3

account balance = initial account balance + transaction amount

                            = 53 + 90 = 143

Transaction 4

account balance = initial account balance + transaction amount

                            = 143 + ( - 229 ) = - 86

Transaction 5

transaction amount = account balance - initial account balance

                                 = 0 - ( -86 ) = 86

The account balance after transaction 3 is 143

The account balance after transaction 4 is -86

Transaction amount of transaction 5 is 0

A real-estate agent earns a commission on a house she sells. Her commission 5% on the first $500,000 ofthe sale price of the house. She then earns a 6% commission for the amount above $500,000 of the salé price of the house. How much commission did the agent earn if she sold a house for $585,000?

Answers

Because 585k > 500k, then the commission would be 6%.

Percent: 6% = 0.06

Now we will multiply the cost of the house by the percentage to find the commission amount:

1) 0.06(585,000) = 35,100

The total amount the agent will receive would be $35,100.

For one thing, Cal and Martha are technically in agreement; 0.1 and 0.10 are the exact same value. To see whether they're right, or whether Angela had it correct, let's take a look at the numbers 0.5 and 0.2.

As fractions, those two values would be [tex] \frac{5}{10} [/tex] and [tex]\frac{2}{10}[/tex], or [tex] \frac{1}{2} [/tex] and [tex] \frac{1}{5} [/tex] when reduced. When you cut the original pizza in half, you cut it into 2 equal slices. Cutting each of those two pieces into 5 equal pieces, we get a total of 5 x 2 = 10 equal slices. So, taking one of those slices at that point - as Angela did - would be taking [tex] \frac{1}{10} [/tex] - or 0.1 - of the whole pizza.

So, both Cal and Martha are correct.

Unit 4 Review & Sample Work Inequalities Solving and Graphing Inequalities Graph the solution sets to the inequalities on the number lines below.


https://gyazo.com/00a920c17b5ad39849d47d70484cca0c

Answers

Final answer:

Graphing the solution sets to inequalities involves using open or closed circles to represent non-inclusive or inclusive endpoints and shading the number line to indicate the direction of the inequality.

Explanation:

To graph the solution sets to the inequalities on number lines, we need to understand and apply the concepts of inequalities and number line graphing. If an inequality has a 'less than' (<) or a 'greater than' (>) symbol, we use an open circle on the number line to indicate that the endpoint is not included in the solution. Conversely, if an inequality includes 'less than or equal to' (\u2264) or 'greater than or equal to' (\u2265), we use a closed circle to show that the endpoint is part of the solution set. The inequality symbol will also determine the direction in which we shade the number line: to the left for 'less than' and to the right for 'greater than'.

For example, if we have an inequality x > 3, we place an open circle at 3 and shade the number line to the right of 3, indicating all numbers greater than 3 are included in the solution set. If the inequality is x \u2265 5, we place a closed circle at 5 and shade to the right, including 5 and all numbers greater than it. Similarly, with x < -2, an open circle would be placed at -2 and the line shaded to the left. Lastly, for x \u2264 -4, a closed circle at -4 with the line shaded to the left indicates the solution set.

Answers

200-20+40

The 16 isn’t in the equation because they are coming back.

So your answer is 220.
Hey You! Let's break this down step by step:


You have 200 people in a race, and 20 drop out. Meaning, you must subtract:

200 - 20 = 180


Next, 16 take a break, so you must subtract again:

180 - 16 = 164


Finally, 40 people are added back, so, you must add:

164 + 40 = 204
