Answer:

y = 3

x = -15        

Step-by-step explanation:

When substituting, we want to get rid of one of the variables. (It's easiest ot find the variable in terms of other variable)

so, we know that...

 x + 5y = 0

    - 5y     - 5y

x = -5y

We can plug this x-value into the second equation to find our y-value:

 3y + 2x = -21

  3y + 2(-5y) = -21

3y - 10y = -21

      -7y = -21

     ÷ -7      ÷ -7

y = 3

So, if x = -5y,

x = -5y

x = -5(3)

x = -15

(we can test these values in one of the original equations):

    x + 5y = 0

(-15) + 5(3)= 0

-15 + 15 = 0

 {true}                        

so, y = 3 ; and x = -15    

hope this helps!! :)

The critical point x = 0 corresponds to a local maximum while the critical point x = -6 is inconclusive.

The critical points of the function f(x) = -x³ - 9x²,  to find the values of x where the derivative of the function is equal to zero or undefined.

Find the derivative of f(x):

f'(x) = -3x² - 18x

Set the derivative equal to zero and solve for x:

-3x² - 18x = 0

Factor out -3x:

-3x(x + 6) = 0

Setting each factor equal to zero gives two critical points:

-3x = 0 => x = 0

x + 6 = 0 => x = -6

Determine the nature of each critical point using the second derivative test:

To apply the second derivative test, derivative of f(x):

f''(x) = -6x - 18

a) For the critical point x = 0:

Evaluate f''(0):

f''(0) = -6(0) - 18 = -18

Since f''(0) is negative, this critical point corresponds to a local maximum.

b) For the critical point x = -6:

Evaluate f''(-6):

f''(-6) = -6(-6) - 18 = 0

Since f''(-6) is zero, the second derivative test is inconclusive for this critical point. It does not determine whether it is a local maximum, local minimum, or neither.

The recursive formula f(n+1) = f(n) + 5, you can find any term in the sequence by starting with the initial term and adding 5 repeatedly.

To represent the given arithmetic sequence where 5 is added to each term to determine each successive term, the recursive formula can be expressed as: f(n+1) = f(n) + 5

In this formula, f(n+1) represents the next term in the sequence, while f(n) represents the current term. By adding 5 to each term, we can generate the next term in the sequence.

For example, let's assume the first term of the sequence is f(1) = a. Then, the second term would be f(2) = a + 5. The third term would be f(3) = (a + 5) + 5 = a + 10, and so on.

The standard error of estimate in a simple linear regression is equal to: a) the square root of the mean squared error.

Standard error of estimate simply refers to the amount of mistake that can be seen when the estimate from the regression analysis is utilized instead of the actual data, and a small estimate error is not necessarily a bad thing.

A. The assumption about errors at different levels is that the variance between two errors is the same as the variance between two other errors. The variance basically refers to the residual. The standard error is computed assuming homoskedasticity, that is, the constant variance of the error terms.

B. The standard error of the estimate is a way to measure the accuracy of the predictions made by a regression model.

For the given initial value problem, the value of y0 for which the solution will have a vertical asymptote at t = 7 and a t-interval of existence −[infinity] is y0 = 0.

For a vertical asymptote at t = 7, and a t-interval of existence −[infinity], the solution to the given initial value problem will have a value of y0 = 0.

To solve this problem, we can use the standard form of the solution for an initial value problem of the form y' = f(t,y). The general solution to this type of problem is given by y = f(t + c), where c is an arbitrary constant.

In this case, we can set the arbitrary constant to be c = -7, so that the solution takes the form y = f(t - 7).

Since the initial condition is given as y(0) = y0, we can solve for y0 by substituting t = 0 in the solution. This gives us y0 = f(-7).

The particular antiderivative that satisfies the given conditions is y(x) = 2x^(3/2) + 5x^(1/2) - 3x.

To find the particular antiderivative that satisfies the given conditions, we will integrate the given function with respect to x and then use the initial condition to determine the constant of integration.

The given function is: (4x + 5) / (3√x).

First, we split the function into two parts:

(4x) / (3√x) + (5) / (3√x).

Now, we integrate each part separately:

∫ (4x) / (3√x) dx = 2x^(3/2) + C1, where C1 is the constant of integration for the first part.

∫ (5) / (3√x) dx = 5x^(1/2) + C2, where C2 is the constant of integration for the second part.

Combining the two parts, we have:

y(x) = 2x^(3/2) + 5x^(1/2) + C, where C = C1 + C2.

Next, we use the initial condition y(1) = 8 to determine the value of C:

y(1) = 2(1)^(3/2) + 5(1)^(1/2) + C = 2 + 5 + C = 7 + C = 8.

Solving for C, we have: C = 8 - 7 = 1.

Therefore, the particular antiderivative that satisfies the given conditions is:

y(x) = 2x^(3/2) + 5x^(1/2) + 1.

The particular antiderivative that satisfies the given conditions is y(x) = 2x^(3/2) + 5x^(1/2) + 1. This antiderivative is obtained by integrating the given function and including the constant of integration determined by the initial condition y(1) = 8.

The probability that X is greater than 145.28 is approximately 0.0465.

Given that X is normally distributed with mean (μ) of 110 and standard deviation (σ) of 21. We are to find the probability that X is greater than 145.28. It can be calculated as follows: We can calculate the Z-score value with the help of the following formula, Z = (X - μ) / σWhere X is the random variable value, μ is the mean, and σ is the standard deviation. Substituting the values in the formula, we get: Z = (145.28 - 110) / 21Z = 1.68476 Using the Z-table, we can find the probability that X is greater than 145.28 as follows: From the Z-table, we get: P(Z > 1.68) = 0.0465

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution.

The given problem states that the ratio of the number of tables to chairs in a restaurant is 4 : 9. After removing 2 tables and 4 chairs, the ratio becomes 7 : 16. After removing 2 tables and 4 chairs, there are 16 tables and 36 chairs left in the restaurant.

Let's assume the number of tables in the restaurant is represented by \($4x$\) and the number of chairs is represented by \($9x$\) (since the ratio is given as 4:9).

According to the given information, if 2 tables and 4 chairs are removed, the new ratio becomes 7:16. This can be represented as

\($\frac{{4x - 2}}{{9x - 4}} = \frac{7}{16}$\).

Cross-multiplying:

\(\[16(4x - 2) = 7(9x - 4)\]\)

Simplifying:

\(\[64x - 32 = 63x - 28\]\)

Subtracting \($63x$\) from both sides and adding 32 to both sides:

\($x = 4$\)

Now, we can find the number of tables and chairs left by substituting \($x = 4$\) them back into the initial representation:

The number of tables: \($4x = 4(4) = 16$\)

The number of chairs: \($9x = 9(4) = 36$\)

Therefore, there are 16 tables and 36 chairs left in the restaurant.

If we roll 9 times, the rolls will result in a sum greater than 9 if the experiment is repeated 144 times.

Probability is a mathematical concept used to describe the likelihood or chance of a specific event occurring within a set of possible outcomes. It is a way to quantify the uncertainty associated with a particular event. The probability of an event can be expressed as a decimal, a fraction, or a percentage. A probability of 0 indicates that an event is impossible, while a probability of 1 means that the event is certain to occur. A probability between 0 and 1 indicates that the event is uncertain and may or may not occur. The probability of an event can be calculated as the ratio of the number of favorable outcomes to the number of possible outcomes.

The surface area of the triangular prism is SA = 83 square units.

The surface area of the triangular prism can be found using the formula SA = bh + 2ls + lb, where b is the base of the triangle, h is the height of the triangle, l is the length of the prism, and s is the slant height of the triangle.

To find the surface area of the triangular prism, we need to calculate the values of b, h, l, and s. The base of the triangle is 6 cm, and the height is 8 cm. The length of the prism is 10 cm. To find the slant height, we can use the Pythagorean theorem, since the triangle is a right triangle.

The slant height is the hypotenuse, so we have s² = 6² + 8² = 100. Taking the square root, we get s = 10 cm. Now we can substitute these values into the formula: SA = (6 cm x 8 cm) + 2(10 cm x 6 cm) + (10 cm x 6 cm) = 48 cm² + 120 cm² + 60 cm² = 228 cm². Therefore, the surface area of the triangular prism is 228 cm².
