The equation of the given  line is y=2/3x-6

We have given the graph of the line and also the equation of the line

[tex]y=-6x+\frac{2}{3}[/tex]

[tex]y=\frac{2}{3}x-6[/tex]

[tex]y=-6x+\frac{3}{2}[/tex]

Answer:

Correct answer not shown on the options.

y = -(1/2)+1

Step-by-step explanation:

Let's find an equation in the format of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).

The slope can be calculated as the Rise/Run of the line between the two given points (-6,4) and (-2,2):

Rise = (2 - 4) = -2

Run = (-2 - (-6)) = 4

Slope = Rise/Run = -2/4 or -(1/2)

In fact, the actual full equation is y= -(1/2)x+1  (See attached graph).

None of the options have a slope of -(1/2).  Either the information on the two points or the options are incorrect.

Answer:

y=[tex]-\frac{1}{2}x[/tex]+1

Step-by-step explanation:

y = mx plus c,where m is the gradient.

∴m =[tex]\frac{y2-y1}{x2-x1}[/tex]=[tex]\frac{2-4}{-2-(-6)}[/tex]=[tex]\frac{-2}{4}[/tex]=[tex]-\frac{1}{2}[/tex]

Equation of a line equals

y-y1=m(x-x1) (Using point (-6, 4) for x1 and y1 values)

y-4=[tex]-\frac{1}{2}[/tex](x-(-6))

y-4=[tex]-\frac{1}{2}[/tex](x+6)

y-4=[tex]-\frac{1}{2}[/tex]x-3

2(y-4)=-x-3(2)(multiply through by 2)

2y-8=-x-6

2y=-x+2(divide through by 2)

y=[tex]-\frac{1}{2}x[/tex]+1

∴the equation of the line is y=[tex]-\frac{1}{2}x[/tex]+1

Given mean of 140 hours and standard deviation of 4 hours with confidence level=98%.

We have to find the lifespan which they should quote to get 98% confident that their batteries meet the guarantee.

See below for the proof of the trigonometry identity

The identity is given as:

(sin(x) + cos(x))² / sin(2x)= csc (2x) + 1

Start by expanding the numerator

(sin²(x) + cos²(x) + sin(2x)) / sin(2x)= csc (2x) + 1

Express sin²(x) + cos²(x) as 1

(1 + sin(2x)) / sin(2x)= csc (2x) + 1

Expand the fraction

1/sin(2x) + sin(2x)/sin(2x) = csc(2x) + 1

Evaluate the quotient

csc(2x) + 1 = csc(2x) + 1

Answer:

NO

Step-by-step explanation:

We can calculated each one out :

7 1/5 x 49 7/5 = 36/5 x 252 / 5 = 9072 / 25
49 2/10 x 7 1/5 = 980 / 10 x 36/5 = 35280 / 50 = 3528 / 5

or a much simpler way is that because both multiplication has 7 1/5 so we only have to compare the other terms, and since 49 7/5 is not equal to 49 2/10 these are not equal. and i didnt notice that till now.

6. The system of equations has no solution.

7. B. Tables - 15 lbs, chairs - 3.5 lbs.

The values of x and y that makes two equations equal is the solution of a system of equations.

6. 3x + 4y = 12 --> eqn. 1

y = 3 - 3/4x --> eqn. 2

Substitute y = (3 - 3/4x) into eqn. 1 to find x:

3x + 4(3 - 3/4x) = 12

3x + 12 - 3x = 12

12 = 12 [unable to solve further for x]

This means that the system of equations has no solution.

7. t = tables

c = chairs

3t + 5c = 62.5 --> eqn. 1

3t + 2c = 52 --> eqn. 2

Subtract

3c = 10.5

c = 3.5 [chairs]

Substitute c = 3.5 into eqn. 2

3t + 2(3.5) = 52

3t + 7 = 52

3t = 52 - 7

3t = 45

t = 15 [table]

Answer:

A, C, and D

Step-by-step explanation:

A) (4x + 3) (2x + 6) is equal to 8x² + 30x + 18 because when you multiply two binomials, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, (4x + 3) (2x + 6) can be rewritten as (4x)(2x) + (4x)(6) + (3)(2x) + (3)(6). This can further be simplified to 8x² + 24x + 18.

C) 2(4x² + 15x + 9) is equal to 8x² + 30x + 18 because when you multiply a number by a binomial, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, 2(4x² + 15x + 9) can be rewritten as 2(4x²) + 2(15x) + 2(9). This can further be simplified to 8x² + 30x + 18.

D) 4(2x² + 7x + 4) is equal to 8x² + 30x + 18 because when you multiply a number by a binomial, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, 4(2x² + 7x + 4) can be rewritten as 4(2x²) + 4(7x) + 4(4). This can further be simplified to 8x² + 28x + 16.

The proper sequence of steps in implementing the model in Excel presented in the textbook is option b which is organize the data, represent the decision variables, represent the objective function, represent the constraints and represent the bounds on the decision variables.

Given process of implementing the model in Excel and we have to choose the correct process.

The process of implementing the model in Excel is as under:

1) Organize the data: In excel, to organize the data we have to put similar items in the same column. We have to design the data so that all rows have similar items in the same column. We have to keep a range of data separate and leave at least one blank column and one blank row between a related data range.

2) Represent the decision variables: Now we have to represent the decision variables according to which logical function performs tasks.

3)Represent the objective function: It is important because on the basis of this all the logical function perform tasks.

4) Represent the constraints: In excel when we are using solver we have to now represent the constraints of the objective function.

5) Represents the bounds on the decision variables.

Hence the proper sequence of steps in implementing the model in excel is Organize the data, represent the decision variables, represent the objective function, represent the constraints, and represent the bounds on the decision variables.

In this vase, with a number line with two points opposite from each other on a number line, the middle of it is always going to be 0.  

Therefore, both points are the same distance away from 0 just in opposite directions.

That means point Q is always going to equal the negative of point P. An example of this is if point p equals 5, point p equals -5.
