Frank and Lisa are analyzing the chart, which shows the speed at which light travels through different media. A 2 column table with 4 rows with the column on the left labeled medium with entries water, air, glass, diamond. The column on the right is labeled speed of light in meters per second and are all times 10 Superscript 8 Baseline with entries 2. 25, 2. 99, 1. 97, 1. 24. Frank says that light travels through diamond with the greatest frequency. Lisa says that light travels through air with the greatest frequency. Which best describes the accuracy of these statements? Frank is correct because light travels through diamond at the slowest speed, and speed and frequency have an inverse relationship. Lisa is correct because light travels through air at the fastest speed, and speed and frequency have a direct relationship. Neither person is correct because light does not change frequency when it travels through different media. Both people are correct because light has both an inverse and a direct relationship with frequency, depending on the media.

Answer:

x = 14/-7

x = -2

It has ONE SOLUTION

Answer:

Step-by-step explanation:

x        - the first number

2x      - two times the first number

2x-9     - 9 less than two times the first number = the second number

3x      - three times the first number

3x+6     -  six more than three times the first number = the third number  

The sum of three numbers is 123:

x + 2x-9 + 3x+6 =123

    6x - 3 = 123

      6x = 126

        x = 21

2x-9 = 2•21-9 = 33

3x+6 = 3•21+6 = 69

Check:  21+33+69 = 123

Answer:

Yes, 5x = y is Proportional and, the constant of proportionality is 5

Step-by-step explanation:

If x and y are proportion, then

∵ 5x = y

→ Switch the two sides

∴ y = 5x

→ Check it if passes through the origin point or not

∵ At x = 0, y = 5(0) = 0

∴ (0, 0) is a point ∈ y = 5x

∴ y = 5x represented graphically by a line passes through the origin

∴ x and y are proportion

∴ y = 5x is the equation of proportional

→ By comparing it with the form of the equation above

∴ k = 5

Answer:

y intercept is -2.

Step-by-step explanation:

Convert the equation to slope-intercept form, or in other words, isolate the y variable. You should get y=(7/4)x-2. the -2 is the y intercept.

Answer:

Graph C

The Y axis is up and down and the x axis is side to side. So first we want to look to see which line crosses the y axis the the up and down black line.

When you are finding a coordinate you set it up like this (x, y). You will find x first and y second.

So we are down to two graphs graph a and graph c. Know both of them cross at the (0,-7) mark but it asks for one other thing a well.

On a graph when something decreases it will go down and when something increases it will go up. So that tells me it is graph C.

Answer:

30 trees

Step-by-step explanation:

Given the policy:

8 trees are cut down 48 trees will be planted

If homeowner is going to cut down five trees on his property how many trees will be planted

Since :

8 trees cut down = 48 planted

5 trees cut down = X

Cross multiply :

8 * X = 48 * 5

8X = 240

X = 240/8

X = 30

Hence, 30 trees will need to be planted

Answer: 30

Answer:

4/3

Step-by-step explanation:

you use slope formula

Answer:

The equation of the line that passes through the points (0, 3) and (5, -3) is [tex]y = -\frac{6}{5}\cdot x +3[/tex].

Step-by-step explanation:

From Analytical Geometry we must remember that a line can be formed after knowing two distinct points on Cartesian plane. The equation of the line is described below:

[tex]y = m\cdot x + b[/tex] (Eq. 1)

Where:

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

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

[tex]m[/tex] - Slope, dimensionless.

[tex]b[/tex] - y-Intercept, dimensionless.

If we know that [tex](x_{1},y_{1}) = (0,3)[/tex] and [tex](x_{2},y_{2})=(5,-3)[/tex], the following system of linear equations is constructed:

[tex]b = 3[/tex] (Eq. 2)

[tex]5\cdot m + b = -3[/tex] (Eq. 3)

The solution of the system is: [tex]b = 3[/tex], [tex]m = -\frac{6}{5}[/tex]. Hence, we get that equation of the line that passes through the points (0, 3) and (5, -3) is [tex]y = -\frac{6}{5}\cdot x +3[/tex].

Answer:

95°

Step-by-step explanation:

1 is opposite to 4. So, (3x+10)° = (4x-15)°

3x + 10 = 4x - 15

10 + 15 = 4x - 3x

25 = x

m(4) = 4x - 15 => 4.25 - 15

100 - 15 = 85 = m(4)

7 is opposite to 6 and 6 is parallel to 4. So, m(4) + m(6) = 180°

85° + m(6) = 180°

m(6) = 95°

6 is opposite to 7, so m(6)=m(7) and answer is 95°

Answer: Y=1/5x-2

Step-by-step explanation:

Answer:

A = 500(1+6%/2)^2t

Step-by-step explanation:

Given the general compound interest formula A = P(1+r/n)^nt. With an initial investment of $500, and percent interest of 6% compounded semi annually(every six months/half a year/twice in one year). A = 500(1+6%/2)^2t .

i.e if given two years of compound interest, t=2. A = 500(1+6%/2)^2(2), 500(1+0.03)^4, 500(1.03)^4, 500(1.12550881), 500(≈1.1255) = 562.75

A = 562.75$ for two years

Answer:

[tex]y = 2[/tex]

Step-by-step explanation:

Given

[tex]5 + y = 7[/tex]

Required

Solve

From the analysis attached to the question, we can solve this equation by subtracting 5 from both sides:

[tex]5 + y = 7[/tex]

[tex]-5 + 5 + y = 7 - 5[/tex]

[tex]0 + y = 2[/tex]

[tex]y = 2[/tex]

Answer:

slope = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 8, 0) and (x₂, y₂ ) = (4, 6) ← 2 points on the line

m = [tex]\frac{6-0}{4+8}[/tex] = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]
