Answer:

Step-by-step explanation:

The white-gloved etiquette mavens at the Emily Post Institute in Vermont say that restaurant tips should be 15% to 20% of the bill's pretax total. The Etiquette Scholar website agrees that you should “tip on the pretax amount of the bill, not on the total.”

What is the range for the following function? y=1/(x+2)+3

LUCKY_DIMON [66]

Answer:

$\large \boxed{\text{C) }\{y: y \in \mathbb{R}, y \ne 3\} }$

Step-by-step explanation:

The range is the spread of the y-values (minimum to maximum distance travelled).

The graph of your function is a hyperbola shifted two units left and three units up from the origin.

There is a vertical asymptote at x = -2, so y does not exist when x = -2. However,

$\displaystyle \lim_{x \rightarrow -{2}^{+}}f(x) = \lim_{x \rightarrow -{2}^{+}}\left (\dfrac{1}{x+2}+3 \right ) = 0 + 3 = 3\\\\\lim_{x \rightarrow -{2}^{-}}f(x) = \lim_{x \rightarrow -{2}^{-}}\left (\dfrac{1}{x+2}+3 \right ) = 0 + 3 = 3$

Since the limit from either side is the same,

$\displaystyle \lim_{x \rightarrow -{2}}f(x) = 3$

The graph below shows the asymptotes of your function.

Thus. y can take any value except 3.

In set builder notation, the range is

$\large \boxed{\mathbf{\{y: y \in \mathbb{R}, y \ne 3\} }}$

The low temperature last month was<br> -5˚F. What is the absolute value of -5?

solong [7]

5

The reason is because |-5| is equal to 5. The absolute value bars make the number positive.

The average of the degree measures of all angles of an octagon is less than the average of the degree measures of all angles of

agasfer [191]

Octagon - 135 degrees

Decagon - 144 degrees

135 / 144 * 100% = 93.75%

Therefore it is 6.25% less

Question 9 of 15 (1 point)

mote1985 [20]

The number is -9

Step-by-step explanation:

Let x be the number then according to given statement

$4x+10 = x-17$

Subtracting 10 from both sides

$4x+10-10 = x-17-10\\4x = x-27$

Subtracting x from both sides

$4x-x = x-x-27\\3x = -27$

Dividing both sides by 3

$\frac{3x}{3} = \frac{-27}{3}\\ x = -9$

<u>Verification:</u>

$4(-9)+10 = -9-17\\-36+10=-26\\-26=-26$

The number is -9
