Answer:

C

Step-by-step explanation:

The domain of a function is a set of values that make the function real and defined. No matter what number you substitute as x, the result is always real. Hence, the domain would be from negative infinity to positive infinity.

Answer:

k = 9/2

Step-by-step explanation:

Constant of proportionality, k = y/x

given: x/y = 2/9

since k = y/x, therefore, k value will now be inverse of 2/9, which is 9/2

Step-by-step explanation:

Answer:

Hypotenuse^2 = Opposite^2 + Adjacent^2

Step-by-step explanation:

Here hypotenuse is c, opposite is a and adjacent is b.

c^2 = a^2 + b^2

16^2 = a^2 + 12^2

a^2 = 16^2 - 12^2

a^2 = 112

a = √112 or 10.58

As the question uses inches I think it would be better if you wrote 10.58 in.

Hopefully this helps!!

Answer:

[tex]1 + 2 = [/tex]

answer

Answer:

Option A: 0

Step-by-step explanation:

Given the multiplication of fractions, [tex]\huge\mathsf{\frac{1}{9} \:\times\frac{24}{25}}[/tex]:

Simply multiply the numerators (together), as well as the denominators.

In other words:

[tex]\huge\mathsf{\frac{1}{9} \:\times\frac{24}{25}\:=\frac{1\:\times\:24}{9\:\times\:25}\:=\:\frac{24}{225}}[/tex]

Since 24 and 225 do not have common multiples, then we cannot simplify the fraction into its lowest terms.

Next, in order to find out which is the closest value to the product, [tex]\huge\mathsf{\frac{24}{225}}[/tex], divide the numerator by the denominator, which gives you the following quotient:

[tex]\huge\mathsf{\frac{24}{225}\:=\:24\:\div\:225\:=\:0.1067}[/tex] or 0.11.

We must compare this quotient with the other options:

Option A) 0: This is a possible answer, since rounding 0.11 to the nearest ones (whole number) is 0.

Option B) 0.5:  Unlikely a valid answer, since the digit on the hundreths place is 0.11, and rounding it up to the nearest tenths will become 0.1.

Option C) 1: Definitely not a valid answer, according to the explanations provided in Options A and B.

For Option D) [tex]\huge\mathsf{\frac{21}{20}}[/tex] , we need to find its equivalent decimal form by dividing its numerator by the denominator:  [tex]\huge\mathsf{\frac{21}{20}\:=\:21\:\div\:20\:=\:1.05}[/tex]. Hence, it is also not a valid answer, according to the explanations provided in Options A and B.

Therefore, the closest value to  [tex]\huge\mathsf{\frac{24}{225}\:=\:0.11}[/tex] is Option A) 0.

15x=-4

Step-by-step explanation:

Answer: f(x) = (x −8)2

Step-by-step explanation:

Answer:

Step-by-step explanation:

x=4

Step-by-step explanation:

To calculate each slope, just take any two points from each table, and plug them into this formula:⤵⤵⤵

(It'll be a bit small btw)

[tex] \frac{y _{2} - y _{1} }{x _{2} - x _{1} } [/tex]

Table 1: I chose points (13,1) and (5,21)

21 - 1 = 20

5 - 13 = -8

Simplified = -5/2 ⬅ Slope

Table 2: I chose points (4,16) and (9,19)

19 - 16 = 3

9 - 4 = 5

3/5 ⬅ Slope

Table 3: I chose points (0,6) and (9,0)

0 - 6 = -6

9 - 0 = 9

Simplified = -2/3 ⬅ Slope

Table 4: I chose points (-8,1) and (-8,17)

17 - 1 = 16

-8 - (-8) = -8 + 8 = 0

Undefined slope (meaning the line will just be verticle)

Table 5: I chose points (2,3) and (3,5)

5 - 3 = 2

3 - 2 = 1

Simplified = 2 ⬅ Slope

Hope this helps :)

Answer:

0.134

Step-by-step explanation:

"By" means multiplied by, so the question is, what's 0.00536 multiplied by 25?

In the first step, we multiply all the numbers in the decimal by 5, and we get 0.02680. In the second, we multiply all the numbers in the decimal by 20, and we get 0.10720. Then we add the two together and get 0.134.

I hope that helped :)

Answer:

-5e/6-2/3=-24

Step-by-step explanation:

Answer:

1. 11 players per team

2. 60 miles per hour

3. 25 games per season

4. 60 words per minute

Step-by-step explanation:

1) 132 players divided by 12 teams = # of players per team

132/12 = 11 players per team

2) 240 miles divided by 4 hours = # of miles per hour

240/4 = 60 miles per hour

3) 125 games divided by 5 seasons = # of games per season

125/5 = 25 games per season

4) 180 words divided by 3 minutes = # of words per minute

180/3 = 60 words per minute

Answer:

  b.  not similar

Step-by-step explanation:

Side SC of the smaller triangle is ...

  96 -57 = 39

So, the side lengths of the small triangle, shortest to longest, are ...

  39, 40, 44

Side ST of the larger triangle is ...

 44 +64 = 108

So, the side lengths of the large triangle, shortest to longest, are ...

  96, 96, 108

These lengths do not have the same ratios as the lengths of the sides in the smaller triangle, so the triangles are not similar.

_____

Additional comment

The larger triangle is isosceles. The smaller triangle is not.

The Answer will equal 4(x-1)(x-6)

Step by step explanation= 4x^2+20x-24, 16x+20x-24, 36x-24= 12x

Answer:

4(x-1) (x-6) as an evaluation OR 12x as the answer since you didn't include what it equals.

Step-by-step explanation:

4x^2+20x-24

16x+20x-24

36x-24

12x

Step-by-step explanation:

formula: y=mx+b

First you gotta find M witch is Slope.

B is the y-intercept which is -2

then you have to do rise/run

so up 2

right 3

= 2/3

so your answer would be

y=2/3-2 because you can't simplify 2/3

Answer:

6,6,6,6,6

Step-by-step explanation:

You’d have to have an odd number of 6s and more than one, so either 3 or 6 of the numbers will have to be 6s

6, 6, 6, 6, 6

5, 6, 6, 6, 7 (the 5 and 7 could be replaced by 4/8, 3/9, 2/10, or 1/11 - as long as balance is preserved)

Answer:

d.

took the test

Step-by-step explanation:

[tex]2 - \frac{x+1}{x-2} - \frac{x-4}{x+2} = \frac{2(x-2)(x+2)}{(x-2)(x+2)} - \frac{(x+1)(x+2)}{(x-2)(x+2)} - \frac{(x-4)(x-2)}{(x-2)(x+2)} \\= \frac{2(x-2)(x+2)-(x+1)(x+2)-(x-4)(x-2)}{(x-2)(x+2)} \\= \frac{2x^{2} -8-x^{2}-3x-2-x^{2} +6x-8 }{x^{2} -4} \\=\frac{3x+(-18)}{x^{2} -4}[/tex]

so : a = 3   b = -18

ok done. Thank to me :>

Answer:

In order to find the inverse of a function, we flip it over the line y=x, or we switch the x and y values in the equation and solve it for y. So let's do the latter:

m(x) = 5x - 5

y = 5x - 5

x = 5y - 5

5y = x + 5

y = (x + 5)/5

Step-by-step explanation:
