Answer:

$10.52 tip should be given to the waiter.. The total bill including tax is $67.33

Step-by-step explanation:

We are given the following in the question:

Pre-tax amount = $52.60

Tip percentage = 20%

Tax percentage = 8$

Tip value =

20\% \times 52.60\\\\=\dfrac{20}{100}\times 52.60\\\\=10.52\$

Thus, $10.52 tip should be given to the waiter.

Tax value =

8\% \times 52.60\\\\=\dfrac{8}{100}\times 52.60\\\\=4.21\$

Total bill =

Pre tax amount + Tip + Tax

=52.60 + 10.52 + 4.21\\=67.33

Thus, the total bill including tax is $67.33

Find the equation of a line passing through the point (2, 3) and having a slope of 3.
Delvig [45]

Answer:

The answer to your question is the letter B) y = 3x - 3

Step-by-step explanation:

Data

Point = (2, 3)

slope = m = 3

Process

To solve this problem just substitute the values given in the slope-point equation.

Formula

               y - y1 = m(x - x1)

   x1 = 2      y1 = 3

-Substitution

              y - 3 = 3(x - 2)

-Expand

              y - 3 = 3x - 6

-Solve for y

             y = 3x - 6 + 3

-Result

             y = 3x - 3

What is the y-intercept Of the function Represented by the table of values belowX -2 1 2 4 7 y 15 6 3 -3 -12
Kipish [7]

Given:

The table of values.

To find:

The y-intercept of the given function.

Solution:

The table of values represents a linear function because the rate of change is constant.

Consider any two points from the given table. Let the two points are (-2,15) and (1,6). Then the equation of the linear function is

y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)

y-15=\dfrac{6-15}{1-(-2)}(x-(-2))

y-15=\dfrac{-9}{1+2}(x+2)

y-15=\dfrac{-9}{3}(x+2)

y-15=-3(x+2)

Adding 15 on both sides, we get

y=-3x-6+15

y=-3x+9

Putting x=0, we get

y=-3(0)+9

y=0+9

y=9

The y-intercept is 9. Therefore, the correct option is C.
