Step-by-step explanation:

(179 * 40) + (179 * 4) = 179 *(40 + 4) = 179 * 44

YES

(100 * 4) + 70*4 + 9*4 =  4 * ( 100 +70 + 9) = 4 * 179

No

4000 + 2800 + 360 + 280 +36 = 7876 = 179 *44

YES

(100 *44) + (70*44) + (9*44) = 44 * (100 + 70 +9) = 44 * 179

YES

179 *(4 +4) = 179 * 8

The 3 real roots of the given equation.

To find the real roots.

Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power. The quadratic formula to solve a quadratic equation ax2 + bx + c = 0 is x = [-b ± √(b2 - 4ac)]/2a.

Given that:

The equation are

[tex]\sqrt{2x+4}=\frac{1}{2x} +1\\[/tex]

By squaring both sides

[tex]2x+4=\frac{1}{4x^{2} }+1+\frac{1}{x} \\\\2x-\frac{1}{x}+3=\frac{1}{4x^{2} }\\\\8x^{3}-4x+12x^{2} -1=0\\ \\8x^{3}+12x^{2}-4x -1=0[/tex]

Solutions for x

x1 = -1.74543

x2 = -0.17169

x3 = 0.41712

Answer:

A) To plot equations in point-slope form, pick one and let x = 0, then solve for y (or -4). That gives you point 1 (0,-4). Then let y = 0 and solve for x (or 2/3). That gives you a second point (2/3,0). Plot the two points and draw the line. Repeat for the second equation (points are (0,-3) and (3/5,0)). Where the lines cross is the solution for both equations.

B) point (1,2) fits both equations.

Step-by-step explanation:

Or solve by brute force...

The solution is where the same X,Y point fits both equations, or Y1 = Y2 and X1 = X2. So the equations in point-slope form (already in point-slope form) equal to each other, solve for X and plug that back into either of the equations to find Y.

6X - 4 = 5X -3

X = 1  so

y = 6X - 4

Y = 6 - 4

Y = 2

Step-by-step explanation:

DISTANCE BETWEEN TWO POINTS

We want to firstly assume that the the three trees lies on the same line

so tress A,B and C are on the same line

Given

The direct distance between A to B= 200 ft

The direct distance between B to C= 300 ft

hence A to C= 200+300= 500ft

let us do a graphical representation for better understanding

A----B-----------C

200ft    300ft

A---------- -----C

      500ft

Multiply the top equation and the bottom by 7.

Answer:

The answer is D: Multiply the top equation by 3 and the bottom equation by 4

Step-by-step explanation:

when you do that, the coefficients for the x on the top and bottom equations both become 12, so you would have to subtract the 2 equations to get rid of x.

Answer:

There are 5 sides in the polygon.

Total perimeter of the polygon is 12.5 cm and it is a regular polygon.

Each side of the polygon is 2.5 cm.

So total number of sides is: Total perimeter of the polygon / Length of each side = 12.5 cm/ 2.5 cm = 5

Hence, the polygon has 5 sides and it is a regular pentagon.

Answer:

   3x -y -30 = 0

Step-by-step explanation:

The reference line for the intercept can be written in standard form as ...

  2x +5y = 20

Setting y=0 and solving for x, we find the x-intercept to be ...

  2x = 20

  x = 20/2 = 10

__

The line perpendicular to the first reference line can use the same x- and y-coordinates, but swapped, with one of them negated. If the line is right-shifted from the origin to the x-intercept point, its equation will be ...

  3(x -10) -y = 0

In general form, this is ...

   3x -y -30 = 0

_____

Additional comments

Perpendicular lines have slopes that are opposite reciprocals of each other. The slope of a line in general form is ...

  m = -(coefficient of x)/(coefficient of y)

The opposite reciprocal of this can be had by swapping the coefficients and negating one of them.

In general form, we like to have the first coefficient positive, so we choose to negate the (new) y-coefficient in this problem.

The general form equation ax+by=0 would define a line through the origin. Using the usual methods for translating functions, we can make the line go through point (h, k) by writing the equation as a(x-h)+b(y-k) = 0. This is the method we used to make the line have the desired x-intercept.

Answer: The number of $12 tickets and $15 sold are 120 and 180 respectively.

Step-by-step explanation:

The given equation is:

12x + 15y = 4140             .....(1)

Where,

x stands for $12 tickets and y stands for $15 tickets

According to the question:

x + y = 300           ....(2)

Now solving equation 1 and 2.

From equation 2:

x = 300 - y

Now putting this expression in equation 1.

12x + 15y = 4140

12(300 - y) + 15y = 4140

3600 - 12y + 15y = 4140

3600 + 3y = 4140

3y = 4140 - 3600

3y = 540

y = 180

And,

x = 300 - y = 300 - 180 = 120

The number of $12 tickets sold = x = 120

The number of $15 tickets sold = y = 180

Thus, the number of $12 tickets and $15 sold are 120 and 180 respectively.
