Write an equation of the line through (5,5)and parallel to the line 4x+3y=-2
Please help
Answers
4x + 3y = -2
Subtract 4x from both sides.
3y = -4x - 2
Divide all terms by 3.
y = -4/3x - 2/3
The slope in this equation is -4/3 (4 down, 3 to the right).
Using that slope, input the coordinates (5, 5) into the equation of a line:
y - y1 = m(x - x1)
y - 5 = -4/3(x - 5)
y - 5 = -4/3x + 20/3
y = -4/3x + 35/3
The equation of the line is y = -4/3x + 35/3.

The student's question seems to be about algebraic operations with an unclear equation, but the provided example with y = 9 + 3x demonstrates how to create a table and graph of a linear equation with a slope of 3 and y-intercept of 9.
Explanation:The student's question involves performing the indicated operations with algebraic expressions that include variables and fractions. The expressions mentioned resemble an equation that could potentially be simplified or solved, but the question as written contains typos and lacks clear structure. Consequently, to provide an accurate answer, we would need the correct and complete version of the equation.
However, in similar problems, one would typically combine like terms, find a common denominator for fractions, and simplify the equation to solve for the variable. For the equation y = 9 + 3x, to create a table of values, one can choose different values of x, substitute them into the equation, and calculate the corresponding y values. Then, plotting these points on a graph would show the linear relationship represented by the equation with a slope (m) of 3 and a y-intercept (b) of 9.

Determine if the lines are parallel, perpendicular, or neither 4x+5y=10 and 5x -4y= 28
Answers
4x + 5y = 10
5y = -4x + 10
y = -4/5x + 2.....the slope here is -4/5...the y int is 2
5x - 4y = 28
-4y = -5x + 28
y = 5/4x - 7...the slope here is 5/4...and the y int is -7
for the lines to be parallel, they would need the same slope and different y intercepts. So, as u can see, they are not parallel because they do not have the same slope.
for the lines to be perpendicular, the lines would have to have negative reciprocal slopes. They do....u have perpendicular lines. To find the negative reciprocal of a number, u flip the number and change the sign. One line had a slope of -4/5....the negative reciprocal is : flip the number making it -5/4....change the sign, making it 5/4...which is the slope of the other line...so these slopes are negative reciprocals.
so u have perpendicular lines
The two lines 4x + 5y = 10 and 5x - 4y = 28 are perpendicular to each other as they have slopes that are negative reciprocals of each other.
What is a slope?The slope is generally defined as the rate of change of the y-axis with respect to the x-axis.
We know we can determine if two lines are parallel or perpendicular to each other by their slope.
If they are parallel they will have the same slope and if they are perpendicular they will have slopes that are negative reciprocals of each other.
Given are two lines 4x + 5y = 10 and 5x - 4y = 28.
We know the equation of a line is y = mx + b.
∴ 4x + 5y = 10 can be written as 5y = -4x + 10 Or y = -(4/5)x + 5/2.
And 5x - 4y = 28 can be written as -4y = -5x + 28 Or y = (5/4)x - 7.
Thus we can conclude that these two lines are perpendicular to each other as (-4/5) is the negative reciprocal of (5/4).

Jim Smith is a salesman who receives a $1,100 draw per week. He receives a 12% commission on all sales. Sales for Jim were $205,000 for the month. Assuming a four-week month, Jim's commission after the draw is
Answers
205,000 - 1,100w - 12% = e
w = weeks he worked
e = earnings
If he works 4 weeks, then we fill in w with 4:
205,000 -1,100(4) - 12% = e
1,100 x 4 = 4,400
Now subtract:
205,000 - 4,400 = 200,600
Now to get his commission, turn the percent into a decimal:
12% ----> .12
Then multiply that by the sales after draws:
200,600 x .12 = 24072
That means that Jim Smith got $24072 from commission.

(c) Determine the difference of outputs of any two inputs that are 3 units apart. Show your work.
(d) What do you notice about the ratios of the differences in the outputs to the input intervals? Explain your answer.
Answers
Consider from x = -5 to x = -4, they are 1 unit apart and the difference of their outputs is given by:
-3 - (-11) = -3 + 11 = 8.
Thus, the value of the output increases by 8 units for each one unit increase in the input.
Part B:
Consider from x = -3 to x = -1, they are 2 units apart and the difference of their outputs is given by:
21 - 5 = 16.
Thus, the value of the output increases by 16 units for each two units increase in the input.
Part C:
Consider from x = 0 to x = 3, they are 3 units apart and the difference of their outputs is given by:
53 - 29 = 24.
Thus, the value of the output increases by 24 units for each three units increase in the input.
Part D:
It can be noticed that the ratio difference in the outputs to the input intervals are equal for all the given input intervals.
i.e 8 / 1 = 16 / 2 = 24 / 3.

LANDSCAPING The equation 3x+7y =105 represents the number of bags of sand x and bags of multch y that can be bought with $105. If no bags of sand are bought, how many bags of mulch can be bought with $105 ?
Answers
To find the answer, plug in 0 for x since you aren't buying any bags of sand and then you have 7y=105 and divide by 7 to find y which is 15.
When no bags of sand are bought, you can buy 15 bags of mulch with $105.
Explanation:To find the number of bags of mulch that can be bought with $105 when no bags of sand are bought, we need to substitute x = 0 into the equation 3x+7y = 105. This will allow us to solve for y.
Since x = 0, the equation becomes:
3(0) + 7y = 105
0 + 7y = 105
7y = 105
Dividing both sides by 7, we get:
y = 15
Therefore, when no bags of sand are bought, you can buy 15 bags of mulch with $105.

Let a and b be real numbers where a=b=0. Which of the following functions could represent the graph below?
f(x)=x(x-a)^3(x-b)^3
f(x)=(x-a)^2(x-b)^4
f(x)=x(x-a)^6(x-b)^2
f(x)=(x-a)^5(x-b)
Answers
Answer:
Option: b is the answer.
( f(x)=(x-a)^2(x-b)^4 )
Step-by-step explanation:
Clearly from the graph of the function we could see that zero is not a root of the polynomial function hence option (a) ( f(x)=x(x-a)^3(x-b)^3 ) and option (c) ( f(x)=x(x-a)^6(x-b)^2 )are discarded.
Now we will check for option (b) and option (d)
As the graph touches the x-axis at two point i.e. a and b that means that both the roots of the polynomial equation are of even degree.
Hence, the correct option is:
option: b ( f(x)=(x-a)^2(x-b)^4 ).
It can be deduced that the option that represents the graph is B. f(x)=(x-a)²(x-b)⁴
How to solve the graphFrom the graph, a and b be real numbers where a=b=0. In this case, zero is not a root of the polynomial function
When the graph touches the x-axis at two point l, it implies that means that both the roots of the polynomial equation are of even degree.
In conclusion, the correct option is B.

What is the value of x in the equation 1/5x-2/3 y = 30, when y = 15?
A.4
B.8
C.80
D.200
Answers
The value of x in the given equation 1/5x-2/3 y = 30 when y = 15 is given by option D. x = 200.
To find the value of x in the equation 1/5x - 2/3y = 30 when y = 15,
substitute the value of y into the equation and then solve for x.
Equation is 1/5x - 2/3y = 30
Substitute y = 15:
1/5x - 2/3(15) = 30
Now, calculate the value of 2/3(15):
2/3 × 15 = 30/3 = 10
Now, the equation becomes:
1/5x - 10 = 30
To isolate the term with x, add 10 to both sides of the equation:
1/5x = 30 + 10
1/5x = 40
Finally, to find x, multiply both sides by 5:
x = 40 × 5
x = 200
Therefore, the value of x in the equation when y = 15 is option D. x = 200.

A floor plan shows the area of a room is 271.25 square feet. if the room is 15.5 feet wide, how long is it?
Answers
Final answer:
The length of the room is calculated by dividing the area of 271.25 square feet by its width of 15.5 feet, resulting in a length of 17.5 feet.
Explanation:
To find the length of the room given its area and width, we will divide the area by the width. The formula for finding the area of a rectangle is Area = length × width. So, to find the length, we can rearrange this formula as length = Area ÷ width, which means dividing the given area by the width.
We know the area of the room is 271.25 square feet and the width is 15.5 feet. So the calculation for the length will be:
Length = 271.25 sq ft ÷ 15.5 ft
Length = 17.5 ft
Therefore, the length of the room is 17.5 feet.
