To solve the system of equations using elimination, we'll eliminate one variable by manipulating the equations.

Let's follow the steps: Given equations: 3x + 2y = -3. 9x + 4y = 3. To eliminate the y variable, we can multiply equation (1) by 2 and equation (2) by -1, which will allow us to add the two equations together: 2(3x + 2y) = 2(-3). -1(9x + 4y) = -1(3). Simplifying the equations: 6x + 4y = -6. -9x - 4y = -3. Now, let's add the two equations together: (6x + 4y) + (-9x - 4y) = -6 + (-3). Simplifying the equation: -3x = -9. Dividing both sides by -3: x = 3. Now that we have the value of x, we can substitute it back into one of the original equations to solve for y. Let's use equation (1): 3(3) + 2y = -3. 9 + 2y = -3. Subtracting 9 from both sides: 2y = -12.  Dividing both sides by 2: y = -6. Therefore, the solution to the system of equations is x = 3 and y = -6.

The solutions of system of equations can be represented as the ordered pair (x, y) = (3, -6).

To determine if 16 disc cases can fit in the box, we need to compare the volume of the box with the combined volume of the disc cases.

The volume of the box is calculated by multiplying its length, width, and height: \(26 cm * 15 cm * 20 cm = 7800 cm^3.\)

The volume of one disc case is calculated in the same way: 1.6 cm * 14.2 \(cm * 19.3 cm = 433.744 cm^3.\)

Since the volume of 16 disc cases would be \(16 * 433.744 cm^3 =\)6939.904 cm^3, which is smaller than the volume of the box,

it is not possible to fit 16 disc cases in the given box.

Based on the factors mentioned above, it is likely that the result of the race to decide who mows the lawn is not a fair decision. To ensure a fair decision, it is important to consider these factors and create a race or method that provides equal chances for both siblings.

To determine if the result is a fair decision, we need to consider the factors that could affect the fairness of the race.

Skill level: If one sibling is significantly faster or more skilled than the other, the race may not be fair. In this case, the faster or more skilled sibling would have an unfair advantage, and the result of the race would not accurately reflect their true abilities.

Randomness: A fair decision should involve an element of randomness to ensure equal chances for both siblings. If the race course or conditions heavily favor one sibling over the other, the outcome may not be fair. For example, if the course has obstacles that one sibling is particularly good at navigating, or if the weather conditions are more favorable to one sibling's strengths, it would introduce unfairness into the race.

External factors: Other external factors such as physical condition, injuries, or fatigue can also affect the fairness of the race. If one sibling is not feeling well or is significantly tired, it would give the other sibling an unfair advantage.

Without specific details about the siblings' abilities, the race course, and other relevant factors, it is difficult to make an exact calculation. However, if any of the above factors are present and give one sibling an unfair advantage, the result of the race would not be fair.

The congruence x³ + x² + 3 ≡ 0 (mod 125) has a unique solution in Z125.  In modular arithmetic, the congruence x³ + x² + 3 ≡ 0 (mod 125)

In modular arithmetic, the congruence x³ + x² + 3 ≡ 0 (mod 125) is asking for values of x in Z125 (the set of integers modulo 125) that satisfy the equation x³ + x² + 3 = 0. When considering congruences, it is helpful to examine the equation modulo the modulus, which in this case is 125. In Z125, there is a unique solution that satisfies this congruence.

This means that there is exactly one value of x between 0 and 124 (inclusive) that, when raised to the power of 3, added to the square of itself, and incremented by 3, yields a result congruent to 0 modulo 125. Other values of x in Z125 do not satisfy the congruence.

So Step 3 is right answer.

(a) The electric flux through surface 1 is zero.

(b) Electric flux through surface 2 = 320 N/C × 4.5 m^2 × cos(35 degrees)

(a) The electric flux through surface 1 is given by the product of the electric field magnitude and the area of the surface, multiplied by the cosine of the angle between the electric field and the surface normal. Since the electric field is directed towards the surface and makes an angle of 35 degrees with the bottom surface, the angle between the electric field and surface 1 is 90 degrees (perpendicular). Therefore, the electric flux through surface 1 is zero.

(b) The electric flux through surface 2 can be calculated using the same formula. The electric field is still directed towards the surface and makes an angle of 35 degrees with the bottom surface. The area of surface 2 is given as 4.5 m^2. Substituting these values into the formula, we have:

Electric flux through surface 2 = E × A × cos(theta)

where E is the electric field magnitude, A is the area of surface 2, and theta is the angle between the electric field and surface 2.

Electric flux through surface 2 = 320 N/C × 4.5 m^2 × cos(35 degrees)

Calculating this expression gives us the value of the electric flux through surface 2.

Answer:

x intercept: -13/2

y intercept: 26

Step-by-step explanation:

x intercept of the line is the point where y = 0

Substitute y = 0 into the expression;

0 - 6 = 4(X+5)

-6 = 4x + 20

4x = -6-20

4x = -26

x = -26/4

x = -13/2

y intercept is the point where x = 0

y - 6 = 4(0+5)

y-6 = 20

y = 20+6

y = 26

Step-by-step explanation:

\(f(x) = {x}^{2} - 12x + 27 \\ g(x) = x - 9 \\ (f \times g)(x) = ( {x}^{2} - 12x + 27)(x - 9) \\ (f \times g)(x) = {x}^{3} - 9 {x}^{2} - 12 {x}^{2} + 108x + 27x - 243 \\ (f \times g)(x) = {x}^{3} - 21 {x}^{2} + 135x - 243\)

A negative correlation means that as the x variable decreases, the y variable tends to decrease as well. In other words, there is an inverse relationship between the two variables.

A negative correlation indicates that when the value of one variable decreases, the value of the other variable also tends to decrease. It implies an inverse relationship between the two variables. For example, if we consider the variables "temperature" and "ice cream sales," a negative correlation would mean that as the temperature decreases, the sales of ice cream also tend to decrease.

To determine the strength of a negative correlation, we can calculate the correlation coefficient, often denoted by "r." The correlation coefficient ranges from -1 to +1, with -1 indicating a perfect negative correlation. The closer the value of "r" is to -1, the stronger the negative correlation between the variables.

In summary, a negative correlation suggests that as the x variable decreases, the y variable tends to decrease as well. It signifies an inverse relationship between the two variables. The strength of the negative correlation can be measured using the correlation coefficient, where values closer to -1 indicate a stronger negative correlation.

A rational number is defined in mathematics as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. A rational number is one that can be expressed as the ratio of two integers, with the denominator not equal to zero.

A rational number is one that can be written as a fraction, a whole number, a decimal that ends like 3.35, or a decimal that repeats.

"A rational number is the product of two rational numbers." Because integers are closed under multiplication, multiplying two rationals is the same as multiplying two such fractions, which will result in another fraction of the same form. As a result, multiplying two rational numbers yields another rational number.

To demonstrate that the product of two rational numbers is also rational, use a direct proof. Assume x and y are both rational. Then there are integers m and n, so x = m/n, and integers p and q, so y = p/q. By multiplying, we get xy = (mp)/ (nq).
