Consider this system of equations and the partial solution below.

6 x + 2 y = 6.
7 x + 3 y = 9.

Multiply the first equation by –3.
Multiply the second equation by 2.
Add the resulting system of equations.

Which terms will cancel when you add the resulting system of equations?

Answers

The first equation will turn into -18x -6y = -18, and the second equation will turn into 14x + 6y = 18. The y terms will cancel out when you add the equations together.

A line contains two distinct points, C and D. Select each correct statement,
Points C and D determine one unique line,
There are infinitely many points between points C and D.
The distance from C to D is equal to the distance from D to C.
O Any line segment that contains point C must also contain point D.

Answers

Answer:

We have a line that passes through points C and D.

a) Points C and D determine one unique line

This is true, there is only one line that passes through a given pair of points, then we can call this line as  "Line CD".

b) There are infinitely many points between points C and D.

This is also true, if we define the points with real numbers in R^2, we will have a dense set, which means that between C and D we can find infinite points.

c) The distance from C to D is equal to the distance from D to C.

Also true, the distance between two points C = (cx, cy) and D = (dx, dy) is defined as:

D = √( (cx - dx)^2 + (cy - dy)^2)

And because we have squares, this will be exactly the same as:

D = √( (dx - cx)^2 + (dy - cy)^2)

Then the distance from C to D, is exactly the same as the distanco from D to C.

d) Any line segment that contains point C must also contain point D.

This is false, we can define infinite segments where the endpoint is C, and does not pass through point D (some examples are given in the image below) So this is the only false option.

Answers

Answer: A; r = square root (S/4pi)

Step-by-step explanation:

1. Divide 4pi on both sides to get r^2 by itself so the left side becomes S/4pi (you do this because 4, pi, and r^2 are being multiplied together on the right side in the original equation so to cancel that out and get r by itself you do the opposite of multiplication)

The equation should now look like r^2 = S/4pi

2. Square root both sides including r to get rid of the r^2 so it becomes just r (also when you square root both sides, you square root all of S/4pi not just S or 4pi but the whole thing)

After you do that, you get r = square root (S/4pi) which is answer A

find x.
find the measurement of angle b
find the measurment of angle c

Answers

Answer:

x = 3

Measurement of angle b: 70 degrees

Measurement of angle c: 70 degrees

Step-by-step explanation:

120° = (15x + 5) + (22x + 4)         (ext. ∠ of △)

120° = 15x + 22x + 5 + 4

(120 - 9)° = 37x

x = (111/37)

x = 3

Measurement of angle b: 22x = 4 = 22(3) + 4 = 66 + 4 = 70 degrees

Measurement of angle c: 15x + 5 = 15(3) + 5 = 45 + 5 = 50 degrees

Hope this helped!

Answer:

x = 3, ∠ B = 70°, ∠ C = 50°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ ADC is an exterior angle of the triangle , then

15x + 5 + 22x + 4 = 120 , that is

37x + 9 = 120 ( subtract 9 from both sides )

37x = 111 ( divide both sides by 37 )

x = 3

Thus

∠ B = 22x + 4 = 22(3) + 4 = 66 + 4 = 70°

∠ C = 15x + 5 = 15(3) + 5 = 45 + 5 = 50°

put these in order from least to greatest

Which is the graph of the linear inequality x – 2y > –6?

Answers

Answer:

uhhh d????

Step-by-step explanation:

Graph D represents the  linear inequality x – 2y > –6.

The given inequality is x – 2y > –6.

We rearrange the inequality as y < (1/2)x + 3

Now we have the inequality in slope-intercept form, y < mx + b, where m is the slope (1/2) and b is the y-intercept (3).

To graph this inequality, you can start by plotting the y-intercept, which is the point (0, 3).

The slope of the graph is 1/2.

However, the inequality is y < (1/2)x + 3, which means the shaded region is below the line.

Hence, graph D represents the  linear inequality x – 2y > –6.

In 25 minutes Jezebel can run 10 laps around the track. Part I) Determine the unit rate for the number of laps she can run per minute. Part II) Find the constant of proportionality for this situation.

Answers

Answer: See explanation

Step-by-step explanation:

a. Determine the unit rate for the number of laps she can run per minute.

This will be calculated as the number of minutes used divided by the number of laps which will be:

= 25 / 10

= 2.5 minutes per lap.

b. Find the constant of proportionality for this situation.

We will use the formula y = kx

where y = 25, x = 10, k = constant of proportionality.

Therefore, y = kx

25 = 10k

k = 25/10

k = 2.5

The constant of proportionality is 2.5

An isotope of iodine has a mass of 134 amu. How many neutrons does the
isotope contain?
A. 67
B.153
C. 81
D. 74

Answers

Answer:

The correct option is C: the isotope of iodine contains 81 neutrons.

Step-by-step explanation:

The mass (A) of the iodine isotope is given by:

[tex]A = Z + N[/tex]

Where:

Z: is the number of protons

N: is the number of neutrons

For iodine Z= 53, so if A = 134 the number of neutrons is:

[tex] N = A - Z = 134 - 53 = 81 [/tex]

Therefore, the correct option is C. The isotope of iodine contains 81 neutrons.
