The equation of the line is y = x.

To find the equation of a line given its graph, you need to follow the steps below.

Step 1: Determine the slope of the line.The slope of the line can be determined using the formula: slope = rise/run or m = Δy/Δx. Rise is the change in the y-coordinates and run is the change in the x-coordinates.

Step 2: Determine the y-intercept of the line.The y-intercept is the point where the line intersects the y-axis. You can determine the y-intercept by looking at the point where the line crosses the y-axis on the graph. The y-intercept is denoted by the letter b.

Step 3: Write the equation of the lineThe equation of the line can be written in slope-intercept form, which is y = mx + b. The slope (m) and y-intercept (b) that were determined in steps 1 and 2 are used to substitute into this equation. Thus, the equation of the line becomes y = slope(x) + y-intercept.

Example:Let's say you are given the graph of a line below: .

Step 1: Determine the slope of the line.To determine the slope of the line, you need to choose two points on the line and calculate the rise and run. Let's choose the points (2, 1) and (4, 3). The rise is 2 (3 - 1) and the run is 2 (4 - 2). Therefore, the slope of the line is: m = 2/2 = 1.

Step 2: Determine the y-intercept of the lineThe line crosses the y-axis at the point (0, 0). Therefore, the y-intercept of the line is b = 0.

Step 3: Write the equation of the line.The equation of the line in slope-intercept form is y = mx + b. Substituting the slope and y-intercept into this equation gives: y = 1x + 0 or y = x.

The quotient of the given problem using laws of exponents is; 6 * 10⁰

We want to express the quotient of the quantity 30 times ten raised to the negative twenty fourth power end quantity divided by the quantity 5 times ten raised to the negative twenty fourth power end quantity.

This is;

(30 * 10⁻²⁴)/(5 * 10⁻²⁴)

Answer:

\(b = 0.3\)

Step-by-step explanation:

Given

\(V = ab^t\)

See attachment for graph

From the graph

V = 20 when t = 0

This implies that:

\(V = ab^t\)

\(20 = ab^0\)

\(20 = a * 1\)

\(20 = a\)

\(a = 20\)

Also:

V = 4 when t = 1.5

So:

\(4 = ab^{1.5\)

Substitute 20 for a

\(4 = 20 * b^{1.5\)

Divide by 20

\(0.2 =b^{1.5\)

\(b^{1.5} = 0.2\)

Take 1.5th root of both sides

\(b = 0.34199518933\)

\(b = 0.3\) --- approximated

The size of the exterior angle in the given 7-sided shape, as shown in the image attached below is: x = 46°.

To calculate the size of the exterior angle in a polygon when the interior angle is known, we can use the following relationship:

Interior angle + Exterior angle = 180°

Given that the interior angle measures 134°, as shown in the image below, we can substitute it into the equation:

134° + Exterior angle = 180°

To isolate the exterior angle, we subtract 134° from both sides of the equation:

Exterior angle = 180° - 134°

Simplifying further:

Exterior angle = 46°

The vοlume οf the prism is 14 cubic feet.

A three-dimensiοnal structure having six rectangular faces is called a prism. It is alsο knοwn as a rectangular cubοid οr a rectangular parallelepiped.

The prism is cοmpletely filled with 1750 cubes that have an edge length οf 1/5 ft. This means that the vοlume οf each cube is \((1/5)^3 = 1/125\) cubic feet.

Tο find the vοlume οf the prism, we can divide the tοtal vοlume οf the cubes by the number οf cubes:

Vοlume οf prism = (Vοlume οf οne cube) x (Number οf cubes)

With the help of proportions in the given similar triangles we know that the value of x is 3.5 units.

Euclidean geometry states that two objects are comparable if they have the same shape or the same shape as each other's mirror image.

One can be created from the other more precisely by evenly scaling, possibly with the inclusion of further translation, rotation, and reflection.

These three theorems—Angle-Angle (AA), Side-Angle-Side (SAS), and Side-Side-Side (SSS)—are reliable techniques for figuring out how similar triangles are to one another.

So, in the given situation:

TR and WY are as follows:

Answer:

1) When the concentration of the antibiotic increase, the number of bacteria colonies decrease

2) There is a relationship between the concentration of the antibiotic and the number of bacterias colonies.

3) The scientists' study

Explanation:

A correlation coefficient is a number between -1 and 1 that gives a measure of the relationship between the variables.

If the correlation coefficient is close to 1, there is a positive relationship between the variables, which means that when one variable increases the other also increases.

If the correlation coefficient is close to -1, there is a negative relationship between the variable, so if one variable increases the other decrease.

If the correlation coefficient is close to 0 there is no relationship between the variables.

Therefore, the sign of the correlation coefficient r = -0.83 tell us that when the concentration of the antibiotic increase, the number of bacteria colonies decrease. So, there is a negative relationship between the variables.

The numerical value -0.83 tell us that there is a relationship between the number of bacteria colonies and the concentration of antibiotic. So, the bacteria is not resistant to the antibiotics.

Finally, if the scientists' study has a correlation coefficient of r = -0.94 that is closer to -1 than the correlation coefficient of the doctor's study r = -0.83, then, the study that suggests a stronger relationship is the scientists' study.

Answer: We have f(x)=3x⁵+6x²-5 and g(x)= 2x⁴+7x²-x+16

                        (f-g)(x)= 3x⁵-2x⁴-x²+x-21

Step-by-step explanation:

Here we have,

Given : f(x)=3x⁵+6x²-5 and g(x)= 2x⁴+7x²-x+16

We know,

(f-g)(x)= f(x)-g(x)

= (3x⁵+6x²-5 ) - ( 2x⁴+7x²-x+16)

On subtracting g(x) from f(x) we get,

(f-g)(x)= (3x⁵+6x²-5  - 2x⁴-7x²+x-16)

On simplify,

 (f-g)(x) =3x⁵-2x⁴-x²+x-21

Hence,

(f-g)(x) = f(x) - g(x) = 3x⁵-2x⁴-x²+x-21

x = p and y = -q

Step-by-step explanation:

The value of x and y

px + qy = p² - q²(equation 1)

qx - py = 2py

{Taking equation 2}

\( \sf qx - py = 2py\)

{Taking py on RHS}

\( \sf qx = 2py \ + py \)

{Dividing both sides by q

\( \sf x = \frac{2pq}{q} + \frac{py}{q} \\ \\ \sf x = 2p + \frac{py}{q} (equation \: 3)\)

{Now substituting the value of equation 3 in equation 1}

\( \sf p(2p + \frac{py}{q} ) + qy = {p}^{2} - {q}^{2} \\ \\ \sf 2 {p}^{2} + \frac{ {p}^{2}y }{q} + qy = {p}^{2} - {q}^{2} \)

{Taking 2p² on RHS and taking LCM on LHS}

\( \sf \frac{ {p}^{2}y + {q}^{2} y }{q} = {p}^{2} - {q}^{2} - 2 {p}^{2} \\ \\ \sf \frac{y( {p}^{2} + {q}^{2} ) }{q} = - ( {p}^{2} + {q}^{2} )\)

{Dividing (p² + q²) both sides}

\( \sf \frac{y}{q} = - 1 \\ \\ \red{ \boxed {\bold{y = - q}} }\)

{Now using value of y in equation 3}

\( \sf x = 2p - \frac{pq}{q} \\ \\ \sf x = 2p - p \\ \\ \red{ \boxed{ \bold{ x = p}}}\)
