How do you know if a graph is inverse or direct?

The cost of one guitar string is obtained as follows:

$1.3.

The costs are obtained using a system of equations, for which the variables are given as follows:

He purchases 25 of each, for a total of $40, hence:

25x + 25y = 40.

x + y = 1.6.

A string costs $1 more than a guitar pick, hence:

y = x + 1.

x = y - 1.

Hence the cost of a string is obtained as follows:

y - 1 + y = 1.6

2y = 2.6

y = 2.6/2

y = $1.3.

The inequality in slope-intercept form is: y ≤ -x - 2.

The linear inequality of a graph can be written in slope-intercept form as y = mx + b, where m is the slope of the line, b is the point on the y-axis where the line intercepts, and "=" would be replaced with the inequality sign, which is determined by the type of boundary line and if the shaded region is above it or below it.

The slope of the line (m) = rise/run = -2/2 = -1.

Y-intercept (b) = -2.

The line is a solid line, and the shaded region is below it, therefore, the inequality sign to use is ≤.

Substitute m = -1 and b = -2 into y ≤ mx + b:

y ≤ -x - 2

The zeros of the given function y = 3p³ – 8p² + 4p are p = 0, p = 2, and p = 2/3

The zeros of a function are the values of the independent variable (in this case, p) for which the function equals zero.

To find the zeros of the function y = 3p³ – 8p² + 4p, we need to set y equal to zero and solve for p.

y = 3p³ – 8p² + 4p = 0

3p³ – 8p² + 4p = 0

We can factor this as p(3p-2)(p-2) = 0

So, the zeros of the function are p = 0, p = 2, and p = 2/3

In the context of the situation, these zeros represent the values of plastic pollution (p) at which the population size of mackerel (y) reaches 0. Therefore, the zero p = 1 represents the amount of plastic pollution that causes the mackerel population to reach p = 0, p = 2, and p = 2/3  represent the solutions.

The equation that can be used to solve for b is b=8 tan(30°).

Trigonometric ratios are the ratios of the sides of a right triangle in relation to its angles. There are six trigonometric ratios: sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot).

These ratios can be used to solve problems involving triangles and to model real-world phenomena in fields such as physics and engineering.

In a right-angle triangle, the three sides are represented by the letters a, b, and c.

a represents the side adjacent to the given angle.

b represents the side opposite to the given angle.

c represents the hypotenuse of the triangle.

Using the trigonometric ratio we can write the ratio as

b/a = tan(30°)

Multiplying both sides by a, we get

=> b = a*tan(30°)

since a=8 so,

b = 8 tan(30°)

Therefore, The equation that can be used to solve for b is b=8 tan(30°).

The constant of proportion in the proportional relationship is 3/2

The constant of proportionality is a value that represents the ratio of two variables in a proportional relationship. The constant of proportionality is represented by the letter "k" in the mathematical equation y = kx, where y and x are the variables in the relationship, and k is the constant of proportionality. It is a fixed value that does not change regardless of the specific values of the variables. The value of k can be determined by dividing the y-value of any point on the relationship by the corresponding x-value of that point.

To determine the constant of proportionality, we have to use the formula;

y = kx

Taking one point from the table;

9 = k(6)

k = 9/6

k = 3 / 2

The scale drawing and applying proportion, the length of the part of the ramp that is on the ground is calculated as 72 inches.

In a scale drawing, proportion can be used to find actual measurements.

height of Felix's ramp = 6 inches

height on scale drawing = 1 inches

Length of ramp on the ground = x = ?

length of ramp on scale drawing = 12 inches

Thus, the following proportion can be created:

6 = 1

x = 12

Cross multiply

x = (6×12)/1

x = 72 inches

Therefore, given the scale drawing and applying proportion, the length of the part of the ramp that is on the ground is calculated as 72 inches.

The likelihood that the player's average will be.310 or higher during the following 100 at-bats is. 9267

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.

The likelihood of obtaining at least 31 hits in 100 at-bats when the likelihood of getting a hit in each at-bat is.300 must be taken into account in order to calculate the likelihood that the player's average during the subsequent 100 times at bat will be.310 or higher.

The likelihood of obtaining at least 31 hits in 100 at-bats when the likelihood of a hit occurring in each at-bat is.

You may calculate 300 as follows:

P(31 hits or more in 100 at-bats) = 1 - P(30 hits or fewer in 100 at-bats)

When the likelihood of getting a hit in each at-bat is, we can determine the likelihood of getting at least 31 hits in 100 at-bats using the normal approximation. the following 300:

P(31 hits or more in 100 at-bats) = 1 - P(30 hits or fewer in 100 at-bats)

substitute the values in the above equation

= 1 - P(z ≤ (30 - 100(.300)) / √(100(.300)(1 - .300)))

simplifying the equation, we get

= 1 - P(z ≤ -1.44)

= 1 - .0733

= .9267

As a result, there is a roughly.9267 chance that the player's average over his next 100 at-bats will be.310 or higher.

Answer:

x = -3

y = 0

Step-by-step explanation:

4x + y = -12

x − 5y = -3

Times the second equation by -4

4x + y = -12

-4x + 20y = 12

21y = 0

y = 0

Now put 0 back in for y and solve for x

4x + 0 = -12

4x = -12

x = -3

Let's check

4(-3) + 0 = -12

-12 + 0 = -12

-12 = -12

So, x = -3 and y = 0 is the correct answer.

Answer:

(-3,0)

x = -3

y = 0

Step-by-step explanation:

4x + y = -12

x − 5y = -3

Enter the second equation by -4

4x + y = -12

-4x + 20y = 12

21y = 0

y = 0

Now enter 0 for y

4x + 0 = -12

4x = -12

x = -3

Plug that info in

4(-3) + 0 = -12

-12 + 0 = -12

-12 = -12

Therefore x = -3 and y = 0

Answer: To simplify the expression (2/7 * x + 5/8) - (1/6 * x - 3/7), we need to combine like terms.

(2/7 * x + 5/8) - (1/6 * x - 3/7) = (2/7 * x) + (5/8) - (1/6 * x) + (3/7)

= (2/7 * x - 1/6 * x) + (5/8 + 3/7)

= (2/7 - 1/6) * x + (5/8 + 3/7)

= (2/42) * x + (40/56)

 A scalar quantity known as speed is used to describe "the rate at which an item changes its position" or "the distance travelled in a unit of time." It is a way to gauge how quickly something is moving and is frequently expressed in terms of the amount of space covered in one unit of time, such as miles per hour (mph) or kilometers per hour (km/h). Speed is calculated as follows: speed = distance / time.

Step 1: To determine a car's speed, divide the distance travelled by the time required.

Step 2: In this instance, the journey took 20 minutes and covered 15 kilometers.

Step 3: Divide the number of minutes by 60 to convert it to hours. Therefore, 20 minutes equals 20/60, or 0.333 hours.

Step 4: Now divide the number of kilometers (km) travelled by the number of hours travelled (0.333 hours)

= 15 km / 0.333 hours

 =45 km/h

Therefore speed of the car is 45km/hr.
