Which function is the inverse of f(x) = 2x + 3

Answer:

Step-by-step explanation:

if two functions are squeezed together at a particular point , then any function trapped between them will get squeezed to that point. the squeeze theorem deals with limit value , rather than function value. the squeeze theorem sometimes called Pinch Theorem.

Answer: The answer is B i just did this test

Step-by-step explanation:

The only number on the list that matches the rounding requirement is 0.579. Hence, the correct option is B.

Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.

Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.

We can consider what the offered numbers are when they are rounded to hundredths:

 0.574 ⇒ 0.57

 0.579 ⇒ 0.58 . . . matches the requirement

 0.585 ⇒ 0.59

 0.681 ⇒ 0.68

The only number on the list that matches the rounding requirement is 0.579.

Hence, the correct option is B.

Answer:

$720 in one week

Step-by-step explanation:

40 * 18

$720

Best of Luck!

Answer:

$720

Step-by-step explanation:

The equation set up for this problem is 40x18 because for every one hour Mr. Thompson works, he earns $18.

Answer: Choice A) $0.20

=======================================================

Explanation:

The store bought the batch for $100, and sold that same batch for $150. The profit of the entire batch is 150-100 = 50 dollars.

Divide this over 250 to get 50/250 = 0.20 dollars.

Their profit is $0.20 per pastry (ie 20 cents per pastry).

-------

You can think of it like this

50 dollar profit = 250 pastries

50/250 dollar profit = 250/250 pastries (dividing both sides by 250)

0.20 dollar profit = 1 pastry

That last equation tells us one pastry yields a profit of $0.20 or 20 cents.

Answer:

$0.20

Step-by-step explanation:

If the purchased is $100 for 250 pastries, then 1 ipastry at purchase is:

$100=250

    ?  = 1

1×100/250 = $0.40 ( at purchase)

Then when resold, the profit is:

if 250 pastries= $150

1 pastry=?

$150× 1/ 250= $0.60

s0, the profit will be $0.60 - $0.40 = $0.20

Answer: x=-7

Step-by-step explanation:

1) The angles of a triangle are equal to 180

2) Add your angles together and set them equal to 180 like this:

x+59+x+51+84=180

3) Combine like terms:

2x+ 194 =180

4) Subtract 195 from both sides:

2x+ 194 =180

    - 194   -194

2x = -14

5) Divide by 2 on both sides

2x= -14

Answer: The 3x+21

Step-by-step explanation:

3(x=4) = (3x+12) The (3x+12) is being multiplied by (x+7) and the 3 should only be distributed to (x+4) which meant the the equation when simplified should have become (3x=12)(x+7).

Answer:

n = s/180 +2

Step-by-step explanation:

180(n-2)=s

Distribute

180n - 360 =s

Add 360 to each side

180n -360+360 = s+360

180n = s+360

Divide each side by 180

180n/180 = s/180 + 360/180

n = s/180 +2

Answer:

[tex]\boxed{\tt x=3}[/tex]

Step-by-step explanation:

We are given the equation:

[tex]5x=15[/tex]

and asked to solve for [tex]x[/tex]. Therefore, we must isolate the variable on one side of the equation.

[tex]x[/tex] is being multiplied by 5. The inverse of multiplication is division. Divide both sides of the equation by 5.

[tex]\frac{5x}{5}=\frac{15}{5}[/tex]

[tex]x=\frac{15}{5}[/tex]

[tex]x=3[/tex]

Let's check our solution. Plug 3 in for x and solve.

[tex]5x=15[/tex]

[tex]5(3)=15[/tex]                      

[tex]15=15[/tex]

This checks out, so we know our solution is correct.

The solution to 5x=15 is x=3.
