The value of the expression given as (9x-26) (4x+43) (2x-12) is 72x³ + 134x²  -5642x + 13416

From the question, the expression is given as

(9x-26) (4x+43) (2x-12)

Next, we evaluate the expression in pairs

So, we have

(9x-26) (4x+43) (2x-12) = (9x-26) (4x+43) (2x-12)

Evaluate the first two factors

So, we have

(9x-26) (4x+43) (2x-12) = (36x² + 387x - 104x  - 1118) (2x-12)

Evaluate the like terms in the expression

So, we have

(9x-26) (4x+43) (2x-12) = (36x² + 283x  - 1118) (2x-12)

Evaluate the first two factors

So, we have

(9x-26) (4x+43) (2x-12) = (72x³ - 432x² + 566x² - 3396x  - 2246x + 13416)

Evaluate the like terms

So, we have

(9x-26) (4x+43) (2x-12) = (72x³ + 134x²  -5642x + 13416)

Remove the bracket

(9x-26) (4x+43) (2x-12) = 72x³ + 134x²  -5642x + 13416

Hence, the solution is 72x³ + 134x²  -5642x + 13416

The correct answer is:  [D]:  " [tex]m = \frac{-5}{2}[/tex]  ".

______
Step-by-step explanation:
We are given:
" 5x  +  2y  =  -10 " ; Find the slope of the equation.
______
Rewrite this equation in slope-intercept format ;

that is:  " y =  mx  + b " ;

      in which:  
        y  remains as single value, as an 'output' ; or 'dependent  
variable', on the 'y-axis' (if graphed);
         isolated on the 'left-hand side' of the equation.
      m  is the coefficient of x in the equation; and represents the slope; for which we shall solve.
           {If there is no slope, then "m = 0" ; and "[0 * x = 0]." };
And the "slope-intercept format" is:  "y = b" }.
       b  represents the "y-intercept" ; i.e. when the line crosses the
"y-axis" when graphed;  that is, the "y-value" of the "coordinate" of the "y-intercept" ; [i.e. the value of "y" when "x = 0" ;  so;  " (0, b) ".

{ Note:  b  can equal "0" ; in those cases:  y = mx + 0 ; write as " y = mx "}.

{ If there is no slope, [i.e. "m = 0" ; and no "y-intercept" ;  [i.e. "b = 0"];
 Then:  write the equation accordingly—e.g. " y = [whatever number the graph represents]." }.

 Also, note that b can be a "negative number"; as well.
  In that case,  write an equation in "slope-intercept format" ; that is;  
   →" y = mx + b " ;   as:   " y = mx " .     
______
Given:  " 5x  +  2y  =  -10 " ;  
 Let's rewrite:    ↔  " 2y + 5x  =  -10 " ;  to get the "y-value" a bit closer to the 'left-hand side' of the equation.

  Then: Let's subtract 5x from Each Side of the equation;
      2y + 5x − 5x  = -10 − 5x  ;

 to get:  " 2y =  -10 − 5x " ;

______
Method 1):
  We have: " 2y = -10 − 5x " ;

 Divide Each Side by 2 ; to isolate y on the 'left-hand side' of the equation, and to rewrite as an equation in the slope-intercept format :

  2y / 2 = (-10 − 5x)/2 ;

   →  [tex]y =\frac{-10-5x}{2}= \frac{-10}{2}-\frac{5x}{2}[/tex] ;
              →    [tex]\frac{-10}{2} =[/tex] -10 ÷ 2  = -5 ;

                   Rewrite the equation by replacing " [tex]\frac{-10}{2}[/tex] " ;  with:  -5 ;
              →  [tex]y = -5 - \frac{5x}{2}[/tex] ;

             Then, rewrite to get the equation in "slope-intercept format"

              →  [tex]y = -5 - \frac{5x}{2}[/tex] ;
                     [tex]= -5 + (-\frac{5x}{2})[/tex] ;  ↔ Rewrite:
                     [tex]= \frac{-5x}{2} + (-5)[/tex] ;   ↔ Rewrite again:
                     [tex]=\frac{-5x}{2} -5[/tex] ;

             →   [tex]y = \frac{-5x}{2} -5[/tex] .

Note:  " [tex]\frac{-5x}{2} = \frac{-5}{2} x[/tex] " ;

            →   [tex]y = \frac{-5}{2}x-5[/tex] ;

 This is the equation written in "slope-intercept format" ;

 that is:  " y = mx + b " ;

  in which:
 y is isolated as a single variable on the 'left-hand side' of the equation;

 m = [tex]\frac{-5}{2}[/tex] ; which is the slope; which is also the "coefficient" of x ;

 b = -5 ; which is the 'y-coordinate' of the "y-intercept" of the graph;
So, the slope; "m = -5/2" ; is the correct answer; which corresponds to:
Answer choice:  [D]: " m = [tex]\frac{-5}{2}[/tex]  " .
______

Method 2):

Given:  " 5x + 2y = -10" ; Find the slope of the line.

We want to rewrite the equation in the "slope-intercept format" ;

" y = mx + b " ; as explained above;

  to get the correct answer for m, the slope of the line.

" 5x + 2y = -10 " ↔ Rewrite as:
  2y + 5x =  -10 ;  since we want to isolate y as a single variable on the 'left-hand side' of the equation;  and by rearranging & rewriting this equation, the 2y is closer to the 'left' of the equation.

Now, subtract 5x from Each Side of the equation:
  2y + 5x − 5x = -10 − 5x ;
  to get:  2y = -10 − 5x ;

Now, Let's multiply the entire equation (i.e. "Each Side") by  -1 ;

to make the equation easier to handle;
    -1(2y) = -1 (-10 − 5x) ;
For the 'left-hand side' of the equation:
 -1*2y = -2y
For the 'right-hand side' of the equation:

Note the 'distributive property of multiplication'; as follows:
    a(b + c) = ab + ac ;
Likewise:  
-1(-10 − 5x) = (-1 *-10) + (-1 *-5x) ;

                 =  (10) + (5x) = 10 + 5x ;

Now, rewrite the entire equation:

-2y = 10 + 5x ;  ↔ Rewrite as;
   -2y = 5x + 10 ;  
Then, we divide Each Side of the equation by -2 ;
  to isolate y as a "single variable" on the 'left-hand side' of the equation;

   and to rewrite the equation in "slope-intercept format" ;

    -2y / -2 = (5x + 10) /-2 ;

    →  [tex]y=\frac{5x+10}{-2} =\frac{5x}{-2} +\frac{10}{-2} =\frac{5x}{-2}+(-5) =\frac{5x}{-2}-5[/tex] ;
    → [tex]y=\frac{5x}{-2} - 5[/tex] ;
which is written in "slope-intercept format" ; that is:
 " y = mx + b " ;

in which:  

y is isolated as a single variable on the 'left-hand side' of the equation;

m = [tex]\frac{5}{-2}[/tex] ; which does equal  " [tex]-\frac{5}{2}[/tex] " ;  which does equal " [tex]\frac{-5}{2}[/tex] " ;

which is the slope of the equation, as well as the 'coefficent of x' ;

b = -5 ; which is the 'y-coordinate' of the "y-intercept".
______
As such:  
The correct answer choice is:  [D]: " m = [tex]\frac{-5}{2}[/tex] " .

Step-by-step explanation:

A ray has a starting point and then continues in one direction.

The maximum area that the farmer can enclose for the rectangular garden is 488 sq ft and the dimensions of the rectangular garden are 24ft and 12 ft respectively.

It is given that a farmer decided to enclose a rectangular garden with one side using the barn of a tree and other 3 sides with 48 ft of fencing.

Let the length of the rectangle be y and the breadth of the rectangle be u.

So perimeter of the fencing needed = y + 2u (as one side is barn)

∴ y + 2u = 48

⇒ y = 48 - 2u (equation 1)

Area = yu (equation 2)

Putting the value of variable y from equation 1 in equation 2 we have,

Area = (48-2u)u

∴ Area = 48u - 2[tex]u^{2}[/tex]

⇒ Area = -2[tex]u^{2}[/tex] + 48u

⇒ Area = -2([tex]u^{2}[/tex] - 24u)

⇒ Area = -2([tex]u^{2}[/tex] - 24u + 144) + 288   (using completing the square method)

⇒ Area = -2[tex](u-12)^{2}[/tex] + 288

So the maximum area is 288 sq units as for any value of u the area value will decrease as seen from the above equation.

So if Area = 288

Then yu = 288

⇒ u = 288/y equation 3

Putting this value in Perimeter equation 1 we have,

y = 48 - 2u

⇒ y = 48 - 2 x [tex]\frac{288}{y}[/tex]

⇒ [tex]y^{2} = 48y - 576[/tex]

⇒ [tex]y^{2} - 48y + 576 = 0[/tex]

⇒ [tex](y-24)^{2}[/tex] = 0

Solving we get y = 24 ft

Hence the value of u is calculated as follows:

⇒ u = 288 / y

⇒ u = 288/ 24 = 12 ft

The maximum area that the farmer can enclose is 488 sq ft and the dimensions of the rectangle are 24ft and 12 ft respectively.

Answer:

3rd answer option (1.6, 1.4)

Step-by-step explanation:

the slope of the lines is different.

to see we transform the equations to the regular slope-intercept form

y = ax + b

with "a" being the slope and "b" being the y-intercept (the y value when x = 0).

1.5x + 0.2y = 2.68

0.2y = -1.5x + 2.68

y = -1.5x/0.2 + 2.68/0.2 = -7.5x + 13.4

1.6x + 0.3y = 2.98

0.3y = -1.6x + 2.98

y = -1.6x/0.3 + 2.98/0.3 = -5.33333...x + 9.93333...

-7.5 is not -5.3333...

so, the lines are not parallel nor overlap at all points.

therefore, they intersect at a point.

(1.6, 1.4) ?

the equations must remain true when using the coordinates :

1.5×1.6 + 0.2×1.4 = 2.68

1.6×1.6 + 0.3×1.4 = 2.98

2.4 + 0.28 = 2.68

2.68 = 2.68 correct

2.56 + 0.42 = 2.98

2.98 = 2.98 correct

yes, they intersect at (1.6, 1.4).

for (3.1, 0.5) already the x coordinate is way too large.

1.5×3.1 or 1.6×3.1 are already by themselves much larger than 2.68 or 2.98.
