Answer:

  (x, y, z) = (2, 1, 3)

Step-by-step explanation:

Cramer's rule says you can find the solution by computing the determinants of the matrices obtained by replacing the corresponding variable coefficients with the constant vector.

The attached shows the resulting matrices for x, y, z and the unmodified coefficient matrix (at far right). The determinants of each are listed below, and the result of dividing the determinant for each variable by the determinant of the coefficient matrix is shown below that. In other words, ...

  [tex]\displaystyle x=\frac{\left|\begin{array}{ccc}-4&1&-3\\9&-2&1\\5&5&-2\end{array}\right| }{\left|\begin{array}{ccc}2&1&-3\\4&-2&1\\3&5&-2\end{array}\right| }=\frac{-138}{-69}=2[/tex]

The other variable values are computed similarly.

The solution by Cramer's rule is (x, y, z) = (2, 1, 3).

Answer: 90000100

Hope that helped! :D

Answer:

90000100

Step-by-step explanation:

20 + 20 = 40

20 + 20 = 40

40 + 40 = 80

80 + 20 = 100

90000000 + 100 = 90000100

Answer: 1/2

Step-by-step explanation:

Answer:

Option C

Step-by-step explanation:

Given :-

And we need to find out the equation of the line .We are here given slope and a point . So we can use the slope point form of the line. As ,

[tex]:\sf\implies m ( x - x_1)= y - y_1 \\\\\sf:\implies \dfrac{-1}{8}(x -0)= y - (-4) \\\\\sf:\implies \dfrac{-x}{8}= y +4 \\\\\sf:\implies \boxed{ \sf\red{y = \dfrac{-x}{8}-4}}[/tex]

Hence the option C is correct.

Step-by-step explanation:

Overpopulation causes killing of animals

Answer:

B) An increase in biodiversity is good for the ecosystem because it provides a variety of species. Overpopulation is not good for the ecosystem because there are more individuals

Step-by-step explanation:

The bigger the ecosystem is, the more producers there are, which makes more consumers.

If there are too many consumers, then more populations will go extinct.

Answer:

x  > 7

Step-by-step explanation:

3x + 7 > 28

First, move over the 7.

3x + 7-7 > 28-7

3x > 21

Then, divide by 3

3x/3 > 21/3

x  > 7

Answer:

[tex]x>7[/tex]

Step-by-step explanation:

We have the inequality [tex]3x+7>28[/tex] and we want to solve it for [tex]x[/tex].

1) Subtract 7 from both sides: [tex]3x + 7 -7>28-7[/tex]

2) Simplify by collecting the terms together: [tex]3x > 21[/tex]

3) Divide both sides by 3 to get [tex]x[/tex] on it's own: [tex]\frac{3x}{3} >\frac{21}{3}[/tex]

4) Simplify: [tex]x > 7[/tex]

So [tex]x[/tex] must be greater than 7 for it to satisfy the inequality [tex]3x+7>28[/tex].

If it is below or equal to 7, it does not work.

Answer:

Step-by-step explanation:

so when the height is zero, that's when the rocket hits the ground.  The equation will have two zeros,  but one would be for a negative time,  or before the rocket is launched.    so we only one the one after the rocket is launched.

use the quadratic formula to solve for  x  ( which is time)

-124 +- sqrt [ [tex]124^{2}[/tex] - 4*(-16)*(127) ] / 2 (-16)

-124 +- sqrt [15376 + 8128 ] / -32

-124 +- sqrt [23504 ] / -32

-124 +- 153.310 / -32

if we take the positive part it will become the negative time so skip that one try the negative part 1st

-124 - 153.310 / -32

-277.310 / -32

8.6659 seconds to hit the ground.    ( time of flight)  aka   TOF

8.67 seconds  ( rounded to nearest 100th)

Answer:

undefined

Step-by-step explanation:

[tex]\boxed{slope = \frac{y1 - y2}{x1- x2} }[/tex]

☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate.

Slope of the line

[tex] = \frac{ - 2 - ( - 10)}{ - 1 - ( - 1)} [/tex]

[tex] = \frac{8}{0} [/tex]

(undefined)

Notice that the 2 points have the same x-coordinate of -1, which means that the line is a vertical line. Vertical lines have an undefined slope.

Answer:

(A) There is convincing statistical evidence that the mean salary for all recent college graduates from the small college is greater than $45,327.

Step-by-step explanation:

According to the National Association of Colleges and Employers, the mean salary for a new college graduate is $45,327. A small college wants to know if the mean salary of their most recent graduates is greater than $45,327.

At the null hypothesis, we test if the mean salary is the expected salary of $45,327, that is:

[tex]H_0: \mu = 45327[/tex]

At the alternate hypothesis, we test if the salary is greater than the expected salary of $45,327, that is:

[tex]H_1: \mu > 45327[/tex]

With all conditions for inference met, a significance test was conducted and a p-value of 0.045 was obtained. Which of the following statements is the most appropriate conclusion using a significance level of a = 0.05?

The p-value of the test if 0.045 < 0.05, which means that there is sufficient evidence to accept the alternate hypothesis, that is, to conclude that the mean salary for all recent college graduates from the small college is greater than $45,327.

This means that the correct answer is given by option A.

Answer:

-4

Step-by-step explanation:

From the qquadratic formula

x1 = [ -b +√(b² - 4ac) ] / 2a

x2 = [ -b -√(b² - 4ac) ] / 2a

When added together the ± square root cancels out leaving

(-b/2a) + (-b/2a) = -b/a

For 2x² + 8x -3 = 0

-b/a = -8/2

-b/a = -4
