The slope of the line below is -1/7. Write a point slope equation of the line using the coordinates of the labeled point

Answer:The answer would be -1

Step-by-step explanation:

First insert the -1 into the equation which would look like this -4(-1)+3 which is then multiplication which would narrow the solution down to -4+3 which a negative plus a positive is a rule called you always subtract and the number with the bigger value determines what sign you use so in this equation it would be 4 since 4 is bigger than 3 which 4-3 equals 1 so then carry the negative sign down with you and that would get you your answer of -1

same thing here, let's pick two points, any two points off the table to get the slope.

[tex]\bf \stackrel{\textit{\large average rate of change}}{\stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{28}-\stackrel{y1}{18}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{2}}}\implies \cfrac{10}{2}\implies 5}[/tex]

The domain of the function is the set of values for x, given as {2,3,4}. The range, which is the set of all output values for y that result when substituting each x value in the domain into the equation, is {8,6,4}.

In this problem, we are given an equation y + 2x = 12 and a domain D = {2,3,4}, which means x takes the values 2, 3, and 4. The domain of a function is all the possible values that x can take. Therefore, in this case, the domain (D) is {2,3,4}.

The range, on the other hand, includes all the corresponding output values that y takes for each x in the domain. The output is determined by plugging each value of the domain (x) into the equation and solving for y:

Hence, the range for this equation, given the domain {2,3,4}, is {8,6,4}.

Step-by-step explanation:

Let x represent temperature change per hour.

We have been given that the temperature is going to steadily drop over the next 4 hours and the temperature changes by the same amount each hour.

So temperature change in 4 hours would be [tex]4x[/tex].

We are also told that the temperature changes by a total of -28°F, so we can represent this information in equation as:

Answer:

7/6

Step-by-step explanation:

Firstly we have to distribute it and write in this form

1/4*12x-1/4*5.6=0.5*3x+0.5*0.7

3x-1.4=1.5x+0.35 ( now that we have multiplied and simplified it we will combine like terms remember whenever you move it to the other side of equal signs it turns the opposite of the sign value eg positive to negative.

subtract 0.35 from both sides leaving the equations as 3x-1.75=1.5x

now we move 3x on other side to combine with 1.5x and 3x becomes negative

-1.75=1.5x-3x

-1.75= -1.5x (divide -1.5 from both sides

-1.75/-1.5=1.5x/-1.5

1.166666666666667=x  

or 7/6 if you left the fraction as it is and didn't simplify further.

Let me know if you don't understand  or need more help .

The student's algebraic equation 1/4 (12x−5.6)=0.5(3x+0.7) simplifies to x = 1.17. This is found by distributing numbers, rearrangement of terms, and final division to solve for x.

The question is an algebraic equation that needs to be simplified and solved. First, distribute the numbers in front of the parentheses to both the terms inside. This gives:

Next, rearrange terms to bring all terms involving x to one side of the equation and constants to the other side. This gives:

Simplify the equation to get:

Finally, divide by 1.5 on both sides to solve for x:

Step-by-step explanation:

To prove that angle 1 is equal to angle 3, we can use the given information and the properties of supplementary angles. Using substitution and algebraic manipulations, we can show that angle 1 is indeed equal to angle 3.

To prove that angle 1 is equal to angle 3, we can use the given information and the properties of supplementary angles.

Given: angle 2 = angle 4 and angle 2 and angle 3 are supplementary.

Since angle 2 and angle 4 are equal, we can substitute angle 4 with angle 2 in the given statement, giving us angle 2 = angle 2. Now, since angle 2 and angle 3 are supplementary, their sum is 180 degrees. So angle 2 + angle 3 = 180 degrees. We can rewrite this equation as angle 2 = 180 - angle 3. Now, we can substitute angle 2 in the equation with angle 4 (which is equal to angle 2), giving us angle 4 = 180 - angle 3. Rearranging this equation, we get angle 3 = 180 - angle 4. Since angle 4 = angle 2, we can substitute angle 4 with angle 2 in the equation, giving us angle 3 = 180 - angle 2. Finally, since angle 3 = 180 - angle 2, and angle 2 = angle 4 (from the given information), we can conclude that angle 1 = angle 3.

Answer: The sequence is to add 12 to each new term.

Step-by-step explanation: The Best way to solve these type of questions is to quests and check. For example, one may notice 3 can be multiplied by 5 to get 15. However, 15 times 5 is 75, not 27, so the rule of multiply by 5 is not correct. Then, you may guess that the rule is to add some number to get the next. One may then notice that it is increasing by 12 each time.

The sequence provided is an arithmetic sequence where each subsequent number is 12 more than the previous one.

The sequence described in your question: 3, 15, 27, 39,... follows a rule of addition. Specifically, each subsequent number in the sequence is 12 more than the preceding number. For instance, 15 is 12 more than 3, 27 is 12 more than 15, and 39 is 12 more than 27, and so on. This sequence can be described as an arithmetic sequence with a common difference of 12.

The rule for the given sequence is that each term is obtained by adding 12 to the previous term.

3 + 12 = 15

15 + 12 = 27

27 + 12 = 39

The equation to relate the number of weeks a computer programmer works to the number of hours worked is h = 40w, where h represents the total hours worked and w represents the number of weeks.

To relate the number of weeks w that a computer programmer works to the number of hours h he or she spends working, we can use a simple multiplication equation. Since we know the programmer works 40 hours per week, the relationship between hours worked and number of weeks can be represented as:

h = 40w

This equation states that the total hours worked (h) is equal to 40 times the number of weeks worked (w). For example, if the programmer works for 2 weeks, the total hours worked would be h = 40 * 2, which equals 80 hours.

Answer:

The equation has only one solution

Step-by-step explanation:

* Lets explain how to solve the problem

- There are three types of solutions for the equations

Case (1)

# Two sides of the equation have different coefficient of the variable

   and same or different numerical terms, then the equation has only

   one solution

- Ex: 2x + 5 = x + 5, lets solve it

∵ 2x + 5 = x + 5

- subtract x from both sides

∴ x + 5 = 5

- Subtract 5 from both sides

∴ x = 0

- Zero is a solution

∴ The solution of the equation is x = 0

- If the numerical terms are different x will be any other value, so the

 equation has only one solution

∴ The equation has one solution

Case (2)

# Two sides of the equation have same coefficient of the variable,

  and different numerical terms, then the equation has no solution

- Ex: 14x - 20 = 14x + 10, lets solve it

∵ 14x - 20 = 14x + 10

- Subtract 14x from both sides

∴ - 20 = 10

- The left hand side not equal the right hand side , then there is

  no value of x can make the two sides equal

∴ The equation has no solution

Case (3)

# Two sides of the equation have same coefficient of the variable,

  and same numerical terms, then the equation has infinitely

  many solutions

- Ex: 3x + 5 = 3x + 5, lets solve it

∵ 3x + 5 = 3x + 5

- Subtract 3x from both sides

∴ 5 = 5

- The left hand side is equal to the right hand side , then x can be

  any value because the two sides is already equal without x

∴ The equation has infinitely many solutions

∵ He will write two expressions simplified , not equal , have different

  coefficients on the variables and equate them, then it is like

  the first case

- That means not same coefficient of the variable, and may be not

 same numerical term

∴ The equation has only one solution

Answer:

One gallon of paint is not enough to paint the bedroom floor

Step-by-step explanation:

step 1

Find the area of the bedroom floor

The area is in the shape of rectangle

so

[tex]A=(11.4)(12.5)=142.5\ ft^2[/tex]

Remember that the bedroom floor will be painted with two coats of paint

so

Multiply the area by two

[tex]A=(2)142.5=285\ ft^2[/tex]

A gallon of paint will cover approximately 150 square feet

[tex]285\ ft^2 > 150\ ft^2[/tex]

therefore

One gallon of paint is not enough to paint the bedroom floor

Final answer:

No, one gallon of paint will not be enough to paint the bedroom floor with 2 coats of paint.

Explanation:

To determine if one gallon of paint will be enough to paint the bedroom floor with 2 coats of paint, we need to calculate the total area of the floor and then divide it by the coverage area of a gallon of paint.

The area of the bedroom floor is calculated by multiplying the length and width together: 11.4 feet * 12.5 feet = 142.5 square feet.

Since we need to apply 2 coats of paint, we need to double the area: 142.5 square feet * 2 = 285 square feet.

Since one gallon of paint covers approximately 150 square feet, one gallon of paint will not be enough to paint the bedroom floor with 2 coats of paint.
