Solve for x.

−5x−4(x−6)=−3

Answers

Answer 1
-5x -(4x-6) = -3      Distribute within parentheses
-5x -4x + 24 = -3   Subtract 24 from both sides, collect like terms
-9x = -27               Divide both sides by -9
x= 3

Answer 2

-5x -(4x-6) = -3      

-5x -4x + 24 = -3  

-9x = -27              

x= 3

Problem:
find line perpendicular to 4x+7y+3=0 passing through (-2,1).

Solution:
We will first find the general form of the perpendicular line.
The perpendicular line has the form
7x-4y+k=0 .........................(1)
by switching the coefficients of x and y, and switching the sign of one of the two coefficients.  This way, the slope of (1) multiplied by that of the original equation is -1, a condition that the two lines are perpendicular. The value of k is to be determined from the given point (-2,1).

To find k, we substitute x=-2, y=1 into equation (1) and solve for k.
7(-2)-4(1)+k=0
=>
k=14+4=18
Therefore the required line is
7x-4y+18=0

If you know the slope of a line and a point the line passes through, you can find the equation of the line using the formula:

y - y_1 = m(x - x_1)

You are given a point the line passes through, (-2, 1).
Now you need to slope of your line.
You are given the equation of a line that your line is perpendicular to.
The slopes of perpendicular lines are negative reciprocals.
If you find the slope of the given line, you can find the slope of the perpendicular line.

Given line:

4x + 7y + 3 = 0

Solve for y:

7y = -4x - 3

y = (-4/7)x - 3/7

The slope of the given line is -4/7.
The slope of the perpendicular is 7/4.

Now we can find the equation of the line using the given point and the slope we just found.

y - y_1 = m(x - x_1)

y - 1 = (7/4)(x - (-2))

y - 1 = (7/4)(x + 2)

4y - 4 = 7x + 14

7x - 4y + 18 = 0

if the mechanical advantages of the component machines in the peeler are 2, 3, and 12, what is the overall mechanical advantage of the apple peeler?

Answers

Final answer:

The overall mechanical advantage of an apple peeler with component mechanical advantages of 2, 3, and 12 is the product of these numbers, which is 72. This implies that the input force applied to the apple peeler is multiplied by 72 times.

Explanation:

The student is asking about the overall mechanical advantage of an apple peeler, which is a complex machine made up of components with individual mechanical advantages. To find the total mechanical advantage of a complex machine, you would multiply the mechanical advantages of each component together.

Given that the mechanical advantages of the component machines are 2, 3, and 12, we can calculate the overall mechanical advantage as follows:

Mechanical Advantage of Component 1: 2

Mechanical Advantage of Component 2: 3

Mechanical Advantage of Component 3: 12

To find the overall mechanical advantage, just multiply these together:

Overall Mechanical Advantage = 2 × 3 × 12 = 72

So, the overall mechanical advantage of the apple peeler is 72. This means the input force is multiplied 72 times.

What is an equation of the tangent line at x = 4, assuming that f(4) = 3 and f '(4) = 2? (enter your answer as an equation using the variables y and x.)?

Answers

The general equation for a line in the case where the slope and one point on the line are known is y-b = m(x-a), where m is the slope and (a,b) is the point.

Here f(4) = 3 corresponds to the point (4,3), and f '(4) = 2 corresponds to the slope of the tangent line at that point.

Thus the equation of the tangent line here is

         y - 3 = 2(x - 4).

An alternative form of this equation would be y = 3 + 2x - 8, or
  
          y = 2x - 5

Why do some absolute value equations have no solution?

Because both positive and negative values have a positive absolute value.

It takes one machine 25 minutes to pick a bale of cotton and another machine 30 minutes to compete the same job. If both machines are used, how long will it take them to pick a bale of cotton?

Answers

Answer:

13.64 minutes

Step-by-step explanation:

The first machine works at the rate x = 1 bale/ 25 min.

The second machine works at the rate y = 1 bale/30 min.

The combined rate is

x + y = 1/25 + 1/30 bales/min

        = (30 + 25)/(25*30) = 55/750

        = 11/150 bales/min

The time for both machines to pick 1 bale of cotton is

(1 bale)/(11/150 bales/min) = 150/11 min = 13.64 min

So if you take rsm, you have to input 13.64 otherwise it won't work. :)

To make 5 apple pies, you need about 2 pounds of apples. How many pounds of apples do you need to make 20 apple pies?

Answers

8 lbs. We have 2 lbs for every 5 pies so the first step is to find out how many sets of 5 we have. We find this out by dividing 20 by 5. 20 divided by 5 is 4, so we have 4 sets of 5. If for every one set, we need 2 lbs of apples, we need to multiply the number of sets by 2. 4*2 is 8, so 8 is our final answer.

Suppose that we have the least squares regression line y = 3 + 2x and that the sum of the squares of the errors (sse) for this line is 13,712. what can be said about the sum of the squares of the errors (sse) for this data set and the line y = 3 + 2.5x?

Answers

Final answer:

The question involves linear regression and the sum of squared errors (SSE), which quantify the total deviation of the response values from the fitted line. If y=3 + 2x is the best-fit line, then the SSE for the line y=3 + 2.5x would be greater than 13,712.

Explanation:

The question involves the concept of linear regression and the sum of squared errors (SSE). The SSE of a regression line is quantified by the difference between the observed and predicted values of the dependent variable, each squared and added together. These show how well the regression line fits the data.

In the context of this question, you're given the SSE for the line y = 3 + 2x. However, you're asked about the SSE for the line y = 3 + 2.5x. Since the slope of this new line is steeper, the predicted y-values will be different from those from the original line and generally farther from the actual data points. Therefore, it can be said that if the line y = 3 + 2x is the best-fit line, then the SSE for the line y = 3 + 2.5x would be greater than 13,712.

Error in prediction is generally greater when we move away from the least-squares regression line. Thus the SSE provides a quantifiable way to determine the line that best fits the data.

The surface area of a cube varies directly as the square of the length of an edge. true or false

Answers

The surface area of a cube is 6 times the surface area of one face.

If the side of the cube is x, then the surface area of one side is x^2, and the total surface area is 6x^2 (because there are 6 squares making up the surface of the cube).

Here, we have A(x) = 6 x^2, which DOES vary directly as the square of the length of an edge, denoted by x.

A = 33
L = 2W - 5

33 = W(2W - 5)
33 = 2W^2 - 5W
-2W^2 + 5W + 33 = 0

-2W + 11 = 0
-2W = -11
W = -11/-2
W = 11/2 or 5.5
