There are 3x-2 trees planted in each row of a rectangular Parcel of land. If there are a total of 24x-16 trees planted and the parcel, how many rows of trees are there in the parcel?

If one raw contains 3x-2 trees & if the total trees in the rectangle are 24x-16, that means Horizontal Rows x Vertical Rows =Total number of trees:

(3x-2) * Vertical Rows = 24x-16 ===> Vertical Rows =(24x-16) / (3x-2)

To which graph does the point (−1, 3) belong? y ≥ 2x + 6 y ≥ 3x − 1 y ≥ −x + 3 y ≥ −2x + 5

Here is your answer:

Solving the equation you would see that:

 3x-1=-3-3-1 = -43 + 4 = 77 + 1 = 8x = 8or  y \geq 3x-1

Therefore your answer is the second option "y ≥ 3x − 1."

QUESTION POSTED AT 31/03/2020 - 10:46 AM

The general form of the equation of a circle is x2+y2−4x−8y−5=0. What are the coordinates of the center of the circle?

The general equation of a circle is  (x-a)^{2} + ( y-b)^{2} =  r^{2} where a and b are the x and y components of the center respectively. 

In order to get into this format, we have to use a method that I'm drawing a blank on the same, my apologies about that.

Anyway, what you want is to first isolate the variable on side so now you have:  x^{2} - 4x +  y^{2} - 8y = 5 (you'll see why I rearranged this soon)

Now you have to make it into an equation that can be simplified into the format stated earlier.

So, You have to take the x & y terms (-4x & -8y in this case) divide them each by two, and then square them.

The result of this step is the equation:  x^{2} -4x + 4 +  y^{2} - 8y + 16 = 5 + 4 + 16 
Notice the new components that have been added (4 & 16) and how the have been added to both sides. That is an important step.

Now we simplify and get: (x-2)^{2} +  (y-4)^{2}  = 25

So the coordinate of the center is: (2,4) and the radius is 5

What is the effect on the graph of the function f(x) = 2x when f(x) is changed to f(3x)? A) vertical stretching B) vertical compression C) horizontal compression D) horizontal stretching

Answer:

C)  Horizontal compression

Step-by-step explanation:

Since, if y = f(x) is a function,

Then y = a f(x) gives a vertical stretch if a > 1 and gives a vertical compression if 0 < a < 1.

Also, y = f(bx) gives a horizontal stretch when 0 < b < 1 and gives a horizontal compression if b > 1.

Here,

The given parent function is,

f(x) = 2x

And, 3 > 1

Thus, by the above statements,

f(3x) will give a horizontal compression.

Hence, Option C is correct.

(08.01)Consider the following system of equations: y = 5x + 6 y = −x − 7 Which description best describes the solution to the system of equations?

If you want an answer to question: You can make the equations equal to each other and solve for x. So, since the y values are the same, we can do 
(+x)5x+6 = -x-7. (+x)
(-6)6x+6= -7(-6)
  (1/6) x 6x= -13 x (1/6)
x= -13/6
Substitute −13/6 for x in y=5x+6:
y=5x(−13/6) + 6
y = -29/ 6.
y= -29/6  and x= -13/6

HELP ASAP PLEASE BRAINLEST ANSWER !!! In two or more complete sentences, compare the number of x-intercepts in the graph of f(x) = x2 to the number of x-intercepts in the graph of g(x) = -x2 +7. Be sure to include the transformations that occurred between the parent function f(x) and its image g(x).

Answer:

The function started facing up with a vertex at (0,0) since 7 was added before squaring , the graph shifts 7 units up so the vertex at (7,0) also , the function is negative do the graph is pointing down.


This means that there are two x- intercepts in g(x) and there was one x- intercepts in f(x).

Anna adds (8x + 12y) and (ax − 6y). If the correct answer is 5x + 6y, what is the value of a? A) −3 B) −5 C) 13 D) 3

Answer:

A) -3

Step-by-step explanation:

Given,

When (8x + 12y) is added to (ax − 6y) the answer is (5x + 6y)

(8x+12y)+(ax-6y)=(5x+6y)

8x+12y+ax-6y=5x+6y

(8+a)x+6y = 5x+6y      ( By combining like terms )

By comparing,

8+a = 5

\implies a = 5 - 8 = -3

Hence, the value of x is -3,

Option A is correct.
