2. y + 2x = 12 for D = {2,3,4}
What’s the domain and range
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}.
Explanation: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:
For x=2, y=12-2(2)=8. For x=3, y=12-2(3)=6. For x=4, y=12-2(4)=4.
Hence, the range for this equation, given the domain {2,3,4}, is {8,6,4}.

How do I solve the expression -4d+3 d if =-1
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

Describe the rule for the sequence.
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.
Explanation: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.

A bedroom is 11.4 feet long amd 12.5 feet wide. Shui wants to paint the floor. A gallon of paint will cober approximately 150 square feet. Will one gallon of paint be enough to paint the bedroom floor with 2 coats of paint? Explain your reasoning
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.

20. A computer programmer works 40 hours per week. What is an equation that
relates the number of weeks w that the programmer works and the number of
hours h that the programmer spends working?
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.

The growth rate for the number of registered users on a popular new
website is 15% per week. Initially, 50 people are registered on the
website. How many people are registered after 4 weeks? Round
your answer to the nearest whole number.
Answer:
I would say 3000
Step-by-step explanation:
Final answer:
To calculate how many people are registered after 4 weeks, apply the formula for exponential growth using the initial 50 users and the 15% weekly growth rate, which gives us 87 registered users after rounding to the nearest whole number.
Explanation:
The process of calculating the number of registered users after 4 weeks with a weekly growth rate of 15% involves using the formula for exponential growth. You start with the initial number of users which is 50 and multiply this by 1 plus the growth rate raised to the power of the number of time periods, which in this case is 4 weeks.
The equation to calculate the number of users after 4 weeks will be 50 × [tex](1.15)^4[/tex].
Now we calculate: 50 × [tex](1.15)^4[/tex] = 50 × 1.749 = 87.45, which when rounded to the nearest whole number is 87 registered users.
1/4 (12x−5.6)=0.5(3x+0.7)
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.
Explanation: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:
3x - 1.4 = 1.5x + 0.35Next, rearrange terms to bring all terms involving x to one side of the equation and constants to the other side. This gives:
3x - 1.5x = 0.35 + 1.4Simplify the equation to get:
1.5x = 1.75Finally, divide by 1.5 on both sides to solve for x:
x = 1.75 / 1.5So, x = 1.17 (rounded to two decimal places).

Prove: angle 1 = angle 3
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.
Explanation: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.

Final answer:
The geometry proof demonstrates that angle 1 is congruent to angle 3 by using properties of supplementary and congruent angles.
Explanation:
The student is asking for help with a proof in geometry, a branch of mathematics. The proof involves understanding the properties of supplementary angles and congruent angles. Here is a step-by-step explanation addressing the problem:
If angle 2 is congruent to angle 4 (Given), then by definition, angle 2 and angle 4 have the same measure.Since angle 2 and angle 3 are supplementary (Given), their measures add up to 180 degrees.Because angle 2 is congruent to angle 4, angle 4 must also be supplementary to angle 3, as it has the same measure as angle 2.Angles supplementary to the same angle are equal to each other. Therefore, angle 1, which is supplementary to angle 4, must be congruent to angle 3.Consequently, we have proven that angle 1 is congruent to angle 3.
