Answer:

0.5

Step-by-step explanation:

Subtract 2.5 from 3

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.

Binary numbers are numbers that are made of only 1 and 0. Now, let us look at the options;

A) 001100110011, 011001100110, 010101010101, 101010101010; This is not well arranged from smallest to biggest because the 2nd and 3rd numbers both have 12 terms but the 2nd term is larger because it starts with 011 while the 3rd term starts with 010 which is not meant to be.

B) 001100110011, 010101010101, 011001100110, 101010101010; Thus is well arranged because unlike the option A above, this one has the second and third term correctly positioned and also the 4th term is the biggest.

Options C & D are not properly arranged for the resaons given in options A and B.

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:

70%of x = 63

70/100 × x = 63

x=63×100/70

x=90

Step-by-step explanation:

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.

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.

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:

Given that the average house price in 2007 was 5% lower than in 2006, while the average house price in 2008 was 5% greater than in 2007, to explain why the average price of house in 2008 is not the same as the average house price in 2006 the following logical reasoning must be carried out:

If, for example, in 2006 the median home price was $ 100,000, a 5% drop in 2007 would bring the median price to $ 95,000. In turn, if this price were to increase by 5% for 2008, said value would rise to $ 99,750. This is so because the 5% is calculated based on a smaller number, with which the rise will be, therefore, also smaller.
