Answer:

$39.04

Step-by-step explanation:

1.Approach

To solve this problem, one must first find the amount of tip that was left, then add the value to the cost of the meal. The amount of tip given can be found by dividing the percent value of the tip by (100) and then multiplying the result by the price of the meal.

2.Find the amount of tip

To find the amount of tip that was left, divide the percent value of the tip by (100). This technique converts the percent into a decimal. After doing so,  multiply the result by the cost of the meal.

Tip as a percent: 15%

Tip as a decimal: 0.15

Amount of tip left:

33.95 * 0.15 = 5.0925

Round the result

~5.09

3.Find the total bill

Disincluding the tax, one now has to add the tip to the cost of the meal to find the total amount paid.

(tip) + (price)

= (5.09) + (33.95)

= (39.04)

4y - 7 = 5x2 - x + 2 + 3y
zalisa [80]

Answer:

y = 9 + -1x + 5x2

Step-by-step explanation:

Simplifying

4y + -7 = 5x2 + -1x + 2 + 3y

Reorder the terms:

-7 + 4y = 5x2 + -1x + 2 + 3y

Reorder the terms:

-7 + 4y = 2 + -1x + 5x2 + 3y

Solving

-7 + 4y = 2 + -1x + 5x2 + 3y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-3y' to each side of the equation.

-7 + 4y + -3y = 2 + -1x + 5x2 + 3y + -3y

Combine like terms: 4y + -3y = 1y

-7 + 1y = 2 + -1x + 5x2 + 3y + -3y

Combine like terms: 3y + -3y = 0

-7 + 1y = 2 + -1x + 5x2 + 0

-7 + 1y = 2 + -1x + 5x2

Add '7' to each side of the equation.

-7 + 7 + 1y = 2 + -1x + 7 + 5x2

Combine like terms: -7 + 7 = 0

0 + 1y = 2 + -1x + 7 + 5x2

1y = 2 + -1x + 7 + 5x2

Reorder the terms:

1y = 2 + 7 + -1x + 5x2

Combine like terms: 2 + 7 = 9

1y = 9 + -1x + 5x2

Divide each side by '1'.

y = 9 + -1x + 5x2

Simplifying

y = 9 + -1x + 5x2

Derive the equation of the line that goes through (−3, 1) and (0, −5).
Oksanka [162]

Answer:

C)  y = -2x - 5

Step-by-step explanation:

\sf let \ (x_1,y_1)=(-3,1)\\\\let \ (x_2,y_2)=(0,-5)

\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-5-1}{0-(-3)}=-2

Point-slope formula: \sf y-y_1=m(x-x_1)

\sf \implies y-1=-2(x-(-3))

\sf \implies y=-2x-5
