Answer:

x > -2

Step-by-step explanation:

Domain is the range is of all possible value for x  in y=  f(x) .

Domain of logarithmic function  log(x) is given by x > 0.

It means any value can greater than x can be plugged in place of x in function log(x).

In the given function  Y= In(x+ 2). In place of x there x+2 .

Thus x+2> 0

subtracting -2 from both sides

=>  x+2 -2> 0-2

=> x > -2

Thus, domain of the function Y= In(x+ 2) is x > -2

Answer:

-5

Step-by-step explanation:

Put the coordinates into the equation the difference of y over the difference of x. for example, -4-(-9)/-6-(-5) then you get 5/-1, which is -5.

Answer:

-5

Step-by-step explanation:

Slope = m = (y2 - y1)/(x2 - x1)

m = (-9 - (-4))/(-5 - (-6)) = (-9 + 4)/(-5 + 6) = -5/1 = -5

Answer: The slope is -5

Answer:

[tex](x-5)^2+(y-2)^2=9\\[/tex]

Step-by-step explanation:

So, you basically want the equation of the circle.

Given:

Center(C): [tex]C(5, 2)[/tex]

[tex]r=3[/tex]

The equation of circle is:

[tex](x-h)^2+(y-k)^2=r^2\\[/tex]

Where, [tex](h, k)[/tex] represents the center point and [tex]r[/tex] is the radius of the circle.

Plotting the values in the equation:

[tex](x-5)^2+(y-2)^2=3^2\\[/tex]

[tex](x-5)^2+(y-2)^2=9\\[/tex]

This is the equation of the circle of center (5, 2) and radius 3.

Answer:

(x-5)2 + (y -2)2 = 9

Answer:

A.) y=3x-1

Step-by-step explanation:

Point-slope form can be shown using the equation: y = mx+b

In this case, m is slope, and b is the y-intercept.

Slope in this graph can be found by finding the rise over the run, or the number of blocks the line moves vertically over the number of blocks the line moves horizontally. The line moves at a rate of 3 blocks up for every 1 block to the right, or 3/1. That means that the slope is 3.

The y-intercept is wherever the line crosses the y-intercept, or wherever x equals 0. This happens at y = -1.

If you plug the slope (3) and the y-intercept (-1) into the equation y = mx+b, you get y = 3x-1.

The answer is the top one to the right

The graph that represents the function g(x) = 2(0.5)ˣ -1 is given.

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.

The relationships between two or more items are frequently represented by the points on a graph.

Given expression,

g(x) = 2(0.5)ˣ -1

To draw the graph take x = 0, 1,2, -1 , -2 and so on .

And draw these numbers in the graph.

Take x=0

g(0) = 1

the point is (0,1)

And now , take x = 1

g(1) = 0

the point is (1,0)

Take x =-1

g(-1) = 3

The point is (-1,3)

Therefore, the graph is given in the image.

Answer:

55 total students

Step-by-step explanation:

Change the percent to a decimal.

40% = 0.4

Divide the number of 8th graders by the decimal to find the total players on the team.

22/0.4 = 55

The total number of students is 55.

Answer:

B. 7m

Step-by-step explanation:

She has 7 classes a day (3+4), and each takes the same number of minutes. If m stands for minutes per class, you can find the total minutes per day by multiplying 7 by m. Therefore the answer is 7m.

Example: Let's say a class takes 30 minutes, you would put 30 in the place of m, 7x30=210, so she would be teaching 210 minutes of yoga class each day.

Answer:

500 mg Carbon Monoxide

1100 mg Carbon Dioxide

Step-by-step explanation:

Weight of total sample = 1600 mg

Percentage of Carbon in Carbon Monoxide = 43%

Percentage of Carbon in Carbon Dioxide = 27%

Percentage of carbon in Mixture = 32%

Let amount of Carbon Monoxide = [tex]x[/tex] mg

Amount of Carbon Dioxide in mixture = (1600-[tex]x[/tex]) mg

Amount of carbon in [tex]x[/tex] mg of Carbon Monoxide =

[tex]x \times 43\%\\\Rightarrow x \times \frac{43}{100} ...... (1)[/tex]

Amount of carbon in (1600-[tex]x[/tex]) mg of Carbon Monoxide =

[tex](1600-x) \times 27\%\\\Rightarrow (1600-x) \times \frac{27}{100}......(2)[/tex]

We know that the sample of 1600 mg contains carbon because of Carbon Monoxide and Carbon Dioxide present in it.

Adding (1) and (2) and equating to 32% of 1600 mg:

[tex]x \times \dfrac{43}{100} + (1600-x) \times \dfrac{27}{100} = 1600 \times \dfrac{32}{100}\\\Rightarrow x \times (43-27) = 1600 \times (32-27)\\\Rightarrow 16x = 1600 \times 5\\\Rightarrow x =500[/tex]

Amount of Carbon Monoxide in sample,[tex]x[/tex] = 500 mg

Amount of Carbon Dioxide in sample = (1600 - [tex]x[/tex]) = (1600 - 500) = 1100 mg

Hence, answer is

500 mg Carbon Monoxide

1100 mg Carbon Dioxide
