Step-by-step explanation:

Answer: D: s∈ (-∞, 3]

Step-by-step explanation:

When we have a function:

y = f(x)

The domain is the set of the possible values we can input in f(x).

In this case, we have:

y = √(3 - s)

Where our variable is s.

So we want to find the possible values of s we can input in that function.

Remember that if y is a real number, then we can not have a negative number inside the square root, because it will lead to an complex solution.

Then the argument of the square root needs to be equal to or larger than zero.

This means that:

3 - s ≥ 0

From this inequality, we can find the possible values of s, which will be the domain.

We need to isolate s.

3 ≥ s

This means that s needs to be smaller than or equal to 3.

Then the domain is:

D: s∈ (-∞, 3]

180° - 125° = 55°

180° - 115° = 65°

180° - 55° - 65° = 60°

180° - 60° = 120°

180° - 120° = 60°

Answer:

x = 120°

Step-by-step explanation:

you can draw a perpendicular base betweeen the two parallel segments and form a pentagon, which has 540 degrees inside.

the two base angles will each be 90°, and we have known values for the other two.

as far as 'x', that angle is vertical to the top angle of the pentagon so we add up all the known values and solve for 'x':

90 + 90 + 125 + 115 + x = 540

180 + 240 + x = 540

x = 540 - (180 + 240)

x = 540 - 420

x = 120

Answer:

Step-by-step explanation:

From the question, we're told that the length of the garden is 3 feet longer than its width. Mathematically, we would have

l = w + 3, where

l = length of the garden

w = width of the garden

Again we're told that this same garden has a walkway of about 2 foot wide. Mathematically we would have that as

W(w) = 2, where

W(w) = width of the garden.

That's all the parameters given in the question

Answer:

-20x+30

Step-by-step explanation:

Using distributive property take -5 and multiply 4x and -6 to that -5

That equals 4 x 5 is 20

add the negative -20

add the x -20x

-5 x -6 = 30

add the final product together

-20x+30

Answer:

-10 or 25 (read my explanation)

Step-by-step explanation:

(-5)2

-5*2=-10

(Unless the 2 is supposed to be an exponent)

If it is supposed to be an exponent the answer is 25

(-5)^2

25

[tex]\huge\boxed{Hi\;there!}[/tex]

(-5)2 means negative five times 2.

The answer is -10.

Remember, if we multiply a negative times a positive, we get a negative number.

This has multiple answers:

(4, -2) (2, -4) (8, -1) (1, -8)

Step-by-step explanation:

4*-2 = -8

-4* 2 = -8

-1*8 = -8

1*-8 =-8

Answer:

no

Step-by-step explanation:

When solving this equation you would substitute the x coordinate for x and the y coordinate for y:

[tex]17=(3*-5)+2[/tex]

Then multiply -5 and 3:

[tex]17=-15+2[/tex]

Then, add it out and you will come to the conclusion that it equals negative 13 not 17. The correct answer would be (5,17).

Answer:

  2/3·fg

Step-by-step explanation:

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

  (ab)^c = (a^c)(b^c)

  (a^b)^c) = a^(bc)

__

We assume your 'x' is a multiplication symbol, so you want to simplify ...

  [tex]3f^4g^3 \times\dfrac{ 8fg^4}{ (6f^2g^3)^2}\\\\=\dfrac{3\cdot8f^{4+1}g^{3+4}}{6^2f^{2\cdot2}g^{3\cdot2}}=\dfrac{24}{36}f^{5-4}g^{7-6}\\\\=\boxed{\dfrac{2}{3}fg}[/tex]

Answer:

The y-intercept is the constant [whole number, the one without a variable] in the equation. So you're looking for the equation that has + 2 at the end, not -2.

Answer:

z=70, y=102

Step-by-step explanation:

180-110 = 70

so, z=70

99+89+70 = 258

360-258 = 102

so, y=102

Answer:

270 = number who get news from print sources

630 =  number who get news from social media

Step-by-step explanation:

Let 3x = number who get news from print sources

and 7x = number who get news from social media

Then 3x + 7x = 900

10x = 900

x = 90

3x = 3(90) = 270 = number who get news from print sources

7x = 7(90) = 630 =  number who get news from social media

Check:  270/630 = 3/7 and 270 + 630 = 900

Answer:

dont say you don't know to be lazy and not work say you don't know when you haven't learned and need to.

The best advice someone has ever given me was to hold on and trust that God will bring me through the storms. There was a time in my life in which I felt the only escape from my troubles was death. Although "Hold on" doesn't sound very encouraging... looking back, it's what was needed for me to get to a point in my life where I cherish my existence.

Step-by-step explanation:

Given

Volume and Surface area of a cube

Required

Which is linear

The volume of a cube is:

[tex]V(x) = x^3[/tex]

While the surface are is:

[tex]A(x) = 6x^2[/tex]

Where x represents the length of the side

A linear function construct is represented as:

[tex]f(x) = mx + c[/tex]

By comparing A(x) and V(x) to f(x):

f(x) do not have any form of exponent while A(x) and V(x) have.

So, we can see that both functions are not linear

Answer:

42 post cards

Step-by-step explanation:

First, let's find how many cards are from each country by multiplying the decimal forms of the percent by the total number of post cards (150).

Reminder: to get the decimal form of a percent you move the decimal point twice to the left!

Africa: (.42)(150) = 63

Europe: (.20)(150) = 30

Asia: (.10)(150) = 15

Add all of them

63 + 30 + 15

= 108

Subtract it from the total

150 - 108

= 42

Another way to do this is to add up the percent's and then subtract it from 100, convert that to decimal form and multiply it by 150. Like this:

42% + 20% + 10% = 72%

100 - 72 = 28

(.28)(150) = 42

Therefore, 42 post cards are from South America.

I hope this helps!!

Answer:

100 + 20 x n = 400

Step-by-step explanation:

If he ended the game with 400 points, and he scored 100 points in the first round, and 20 points every round after that, then we have to find out how many rounds he played using multiplication and addition. n represents the number of rounds he played, which is what we want to find out. What number do you have to multiply 20 by to get 300? the answer is 10. Therefore, n is 10.
