Answer: Since x2=6, the width of the rectangle is x-6.

Explanation: factor x^2-4x-12.

given that length=x+2 and area of rectangle = length * width

all you have to do is find the width

there are several way to do this, here is one:

Since one factor of x^2-4x-12 is x+2, x1=-2 is a solution to x62-4x-12=0 so in order to find the other solution, you can use the sum and product properties.

x1*x2= -12 with x1=-2, so x2=6.

Since x2=6, the width of the rectangle is x-6.

Answer:

there is no solution, meaning the lines would be parallel

Answer:

(0, 3 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

Here (x₁, y₁ ) = (- 4, 8) and (x₂, y₂ ) = (4, - 2) , then

midpoint = ( [tex]\frac{-4+4}{2}[/tex], [tex]\frac{8-2}{2}[/tex] ) = ( [tex]\frac{0}{2}[/tex], [tex]\frac{6}{2}[/tex] ) = (0, 3 )

Answer:

The location of the new cell phone tower is [tex](h,k) = (3,4)[/tex], and the equation of the circle is [tex]x^{2}+y^{2} -6\cdot x - 8\cdot y = 0[/tex].

Step-by-step explanation:

The location of the cell phone tower coincides with the location of a circunference passing through the three cell phone towers. By Analytical Geometry, the equation of the circle is represented by the following general formula:

[tex]x^{2} + y^{2}+A\cdot x + B\cdot y +C = 0[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]A[/tex], [tex]B[/tex], [tex]C[/tex] - Circunference constants.

Given the number of variable, we need the location of three distinct points:

[tex](x_{1},y_{1}) = (6,0)[/tex]

[tex]36 +6\cdot A + C = 0[/tex]

[tex](x_{2},y_{2}) = (8,4)[/tex]

[tex]80 + 8\cdot A + 4\cdot B + C = 0[/tex]

[tex](x_{3},y_{3}) = (3,9)[/tex]

[tex]90 + 3\cdot A + 9\cdot B + C = 0[/tex]

Then, we have the following system of linear equations:

[tex]6\cdot A + C = -36[/tex] (2)

[tex]8\cdot A +4\cdot B + C = -80[/tex] (3)

[tex]3\cdot A + 9\cdot B + C = -90[/tex] (4)

The solution of this system is:

[tex]A = -6[/tex], [tex]B = -8[/tex], [tex]C = 0[/tex]

By comparing the general form with the standard form of the equation of the circunference is:

[tex]A = -2\cdot h[/tex] (5)

[tex]B = -2\cdot k[/tex] (6)

[tex]C = h^{2}+k^{2}-r^{2}[/tex] (7)

Where:

[tex]h[/tex], [tex]k[/tex] - Coordinates of the center of the circle.

[tex]r[/tex] - Radius of the circle.

If we know that [tex]A = -6[/tex], [tex]B = -8[/tex] and [tex]C = 0[/tex], then coordinates of the center of the circle and its radius are, respectively:

[tex]h = -\frac{A}{2}[/tex]

[tex]k = -\frac{B}{2}[/tex]

[tex]r = \sqrt{h^{2}+k^{2}-C}[/tex]

[tex]h = 3[/tex], [tex]k = 4[/tex], [tex]r = 5[/tex]

The location of the new cell phone tower is [tex](h,k) = (3,4)[/tex], and the equation of the circle is [tex]x^{2}+y^{2} -6\cdot x - 8\cdot y = 0[/tex].

Answer:

5 15/48

Step-by-step explanation:

5 times 3 is 15,  8 times 6 is 56, and 5 times 1 is 5....you can not simplify 15/48 so the final answer is 5 15/48

Answer:

Step-by-step explanation:

Find an ordered pair that satisfies the equation 5x + y = 3.  

There are infinitely many ordered pairs that satisfy this equation.

If we were to choose y = 0, then 5x = 3, and x = 3/5, leading to the ordered pair (3/5, 0).

If we were to choose x = 1, then 5(1) + y = 3, or y = -2.  The ordered pair would be (1, -2).

And so on.

Answer:

0, -7, 4

Step-by-step explanation:

Zeros of a function are values that make the function = 0

So, f(x) = 2x(x + 7)(x - 4) = 0

                x = 0 or x + 7= 0  or x - 4 = 0

                                   x = -7           x = 4

Note:  If you were to graph f(x), the graph would intercept the x-axis at 0, -7, and 4

Answer:

x = 38°

Step-by-step explanation:

in the given question,

the two angles are complementary, because sum of their measures = 90°

so,

=》52° + x = 90°

=》x = 90° - 52°

=》x = 38°

Answer:

x = 38

Step-by-step explanation:

I first took the measure of a right angle (90 degrees) Then, I subtracted 52 degrees from 90. After that I added 52 and 38 to check. The answer was 38.

x= -7 and x= -3

Step-by-step explanation:

(x+7)(x+3)=0 (Think about the numbers that will add to 10 and multiply to 21)

x= -7 and x= -3

Answer:

x = −3 or x = −7

Step-by-step explanation:

Let's solve your equation step-by-step.

x^2 +  10x + 21 = 0

Step 1: Factor left side of equation.

(x+3) (x+7) = 0

Step 2: Set factors equal to 0.

x + 3 = 0 or x + 7 = 0

x = −3 or x = −7

Answer: -6, -10.

The question is asking you to make the coordinates negative and then multiply the negative numbers by 2, thus, -6, -10.

The coordinate of (x, y) is (-3/2, -5/2) if the -2(x, y) → (3, 5) option second is correct.

It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).

We have:

-2(x, y)  →  (3, 5)

The coordinate (x, y) changes after multiplication by factor 2

New coordinate = (3, 5)

-2x = 3

x = -3/2

-2y = 5

y = -5/2

Thus, the coordinate of (x, y) is (-3/2, -5/2) if the -2(x, y) → (3, 5) option second is correct.
