(1, 0, 2)

Step-by-step explanation:

[3   -1  2 | 7  ]

|6 -10  3 | 12|

[1   -1   4 |  9 ]

To the first row, add -3 times the values of the third row

To the second row, add -6 times the values of the third row

[0   2  -10 | -20 ]

|0  -4  -21 | -42 |

[1    -1    4 |  9   ]

To the second row, add 2 times the values in the first row

[0   2  -10 | -20 ]

|0  0  -41  | -82 |

[1    -1    4 |  9   ]

z =  -82 / -41

z = 2

What is the y-intercept of the graph of the equation ?

Answers

Tryna boost my score for college math could you give me the brainiest and a thanks? Hope you find your answer your looking for!

Answer:

Step-by-step explanation:

It is the point where the graph passes through the y-axis.

So if it passes through the point where y = 2,  the y-intercept is (0, 2) - note the x coordinate is 0 at this point.

If we are asked to find the y-intercept of the graph of the equation y = 3x - 4

we put  x = 0 and work out y as follows:

y = 3(0) - 4 = 0 - 4

y = -4

so the y-intercept is (0, -4).

36. What number shows a temperature of 9° below zero?​

Answers

Answer:

-9*

Step-by-step explanation:

1. anything below zero is negative

2.if you say a positive temperature such as this example (9) then say below zero it is is always going to be a negative temperature

A temperature of 9° below zero is represented by the number -9.

The negative sign indicates that the temperature is below zero on the Celsius or Fahrenheit scale. It means that the actual temperature is 9 degrees lower than the freezing point of water. For example, if the freezing point is 0°C, a temperature of -9°C would indicate that it is 9 degrees below freezing.

Similarly, on the Fahrenheit scale, a temperature of -9°F would indicate that it is 9 degrees below the freezing point of 32°F. Negative temperatures signify colder conditions than the reference point of zero degrees.

Therefore, a temperature of 9° below zero is represented by the number -9.

what is the average rate of change from 2 to 9 of the function represented by the graph?

Answers

Answer:

-3/7

Step-by-step explanation:

It is asking to find the slope of the secant line going through points (2,f(2)) and (9,f(9)).

We must find f(2) by looking at the curve at x=2. We should see that y=2 there so f(2)=2.

We must find f(9) by looking at the curve at x=9. We should see that y=-1 there so f(9)=-1.

The slope of a line is calculated by finding the ratio of the change of y to the change of x.

(-1-2)/(9-2)

(-3)/(7)

Suppose y varies inversely with x, and y = -1 when x = 6. What inverse variation equation relates x and y?

NO LINKS OR ANSWERING QUESTIONS YOU DON'T KNOW!!!
a. y = 6/x
b. y = -12x
c. y= -6x
d. y= -6/x​

Answers

Answer:

[tex]\displaystyle \text{d. }y=\frac{-6}{x}[/tex]

Step-by-step explanation:

If two values [tex]x[/tex] and [tex]y[/tex] are inversely proportional, their product is always some maintained constant (the product of [tex]x[/tex] and [tex]y[/tex] is always maintained). This way, if one goes up, the other must go down by the same extent. By definition, this represents an inversely proportional relationship.

Therefore, we can simply find this constant by multiplying the given values of [tex]x[/tex] and [tex]y[/tex]:

[tex]xy=k,\\6\cdot (-1)=-6[/tex]

The constant [tex]-6[/tex] must be maintained as the product of [tex]x[/tex] and [tex]y[/tex] for all values of [tex]x[/tex] and [tex]y[/tex] for them to be inversely proportional. Thus, we have the equation:

[tex]xy=-6[/tex]

Divide both sides by [tex]x[/tex] to isolate [tex]y[/tex]:

[tex]\boxed{y=\frac{-6}{x}}[/tex]

Answer:

d. [tex]\displaystyle y = \frac{-6}{x}[/tex]

Round this number to the nearest 100,000

Answer:

900,000

Step-by-step explanation:

rounding is quite simple, the number 927,545, like all numbers, has different number places/values. the number 9 is in the 100,000th place and to round you look at the number in the place to the right of it which is 2. the number 2 is is less than 5 so it can't raise the number 9 to a ten. because of this, it reduces all of the other numbers to 0. leaving you with the number 900,000

Answers

Answer:

  (c)  16.5 cm^2

Step-by-step explanation:

The area of each triangle is given by the formula ...

  A = 1/2bh

Smaller triangle area = (1/2)(2 cm)(6 cm) = 6 cm^2

Larger triangle area = (1/2)(5 cm)(9 cm) = 22.5 cm^2

The difference in area is ...

  22.5 cm^2 -6 cm^2 = 16.5 cm^2

2x+5 3x+ 5 X+ 1
x² – 3x X² – 9x x²-g

Answers

Answer:

(x + 5)(x + 2) / (x³ - 9x)

Step-by-step explanation:

We need to find a common denominator.

factor each denominator

x² - 3x = x(x - 3)

x³ - 9x = x(x² - 9) = x(x + 3)(x - 3)

x² - 9 = (x + 3)(x - 3)

As the factors of the first and third denominators are subsets of the second, the second is the LCD. This immediately eliminates the last two options as possible solutions.

Now we multiply each term by the missing factor over itself (1)

(2x + 5)(x + 3) - (3x + 5) - (x + 1)(x)]

(x² - 3x)(x + 3)   (x³ - 9x)  (x² - 9)(x)

[(2x² + 11x + 15) - (3x + 5) - (x² + x)] /  (x³ - 9x)

[2x² + 11x + 15 - 3x - 5 - x² - x] /  (x³ - 9x)

(x² + 7x + 10) /  (x³ - 9x)

(x + 5)(x + 2) / (x³ - 9x)

If the area of the square above is 144 what is the value of x

Answer:

It should be 12, but x wasn't defined. My condition could be wrong though.

If the area of the square above is 144. The value of x is the length of the side of the square which is 12 units.

What is the area of a square?

The area of a square can be calculated as the square of the sides of a given figure.

The area of a square = side x side

We have given the area of the square above is 144.

Let x be the side of the given square.

The area of a square = side x side

[tex]144 = x \times x\\\\144 = x^2\\\\x =\sqrt{144} \\\\x = 12[/tex]

Hence, the length of the side is 12 units.
