15) Evaluate the following expression for x=0.2 and y=3.4: x(y2 - 4)

Answers

Answer:

x(y² - 4) = 1.512

Step-by-step explanation:

We need to evaluate the following expression for x = 0.2 and y = 3.4 :

x(y² - 4)

Put the values of x and y.

x(y² - 4) = (0.2)((3.4)² - 4)

= (0.2)((3.4)² - 4)

= 0.2×7.56

= 1.512

So, the value of the above expression is 1.512

(-4,6), slope=-1

Write the slope-intercept equation using the given information.

Answers

Answer:

y = -x +2

Step-by-step explanation:

y = mx + b

y=6

x=-4

m=-1 (m is the slope)

b=? (b is the y-intercept)

Putting these numbers into this equation,

6 = -1(-4) + b

b=6-4

b=2

So the equation is y = -1x + 2

or just y = -x +2

What is the slope and equation of a line parallel to the y-axis passing through point (9, -1)?
O A. The slope is zero and the equation of the line is y=-1.
O B. The slope is undefined and the equation of the line is y = -1.
O C. The slope is undefined and the equation of the line is x = 9.
D. The slope is zero and the equation of the line is x

Answers

Answer:

The slope is undefined and the equation of the line is x = 9 ⇒ C

Step-by-step explanation:

Parallel lines have the same slopes and different y-interceptsThe slope of any vertical line is undefinedThe equation of any vertical line is x = a, where a is the x-coordinate of a point that lies on the lineAll x-coordinates of the points lie on a vertical line equal

Let us solve the question

∵ The line is parallel to the y-axis

∵ The y-axis is a vertical line

→ By using the second note above

∴ The slope of the y-axis is undefined

→ By using the first note above

∴ The slope of the line is undefined

→ By using the third note above

∵ The equation of the vertical line is x = a

∵ a is the x-coordinate of a point on the line

∵ The line passes through the point (9, -1)

∴ a = 9

∴ The equation of the line is x = 9

Olive is going to buy a scooter that costs $95. The sales tax rate is 8.5%. What is the total cost of the scooter including tax to the nearest cent?

Answers

Answer:

$103.08

Step-by-step explanation:

The total cost of the scooter including tax to the nearest cent will be $103.08.

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

Olive is going to buy a scooter that costs $95. The sales tax rate is 8.5%.

The amount of the sales tax will be

Sale tax = 8.5% of $95

Sale tax = 0.085 × $95

Sale tax = $8.075

The total cost of the scooter including tax to the nearest cent will be

Total cost = $95 + $8.075

Total cost = $103.075 ≈ $103.08

The total cost of the scooter including tax to the nearest cent will be $103.08.

When Sergio went to dinner with his brother, the bill was $51.19. What was the total they paid if they left a 15% tip?

Answers

Answer:

The total they paid was $58.8685

Step-by-step explanation:

Let us solve the question using the percentage method

∵ Sergio went to dinner with his brother

∵ The bill was $51.19

∵ They left a 15% tip

→ That means they pay extra money 15% of $51.19

∴ The total they paid = the bill + 15% of the bill

∵ 15% of the bill = 15% × 51.19

→ Change 15% to a decimal by divide it by 100

∴ 15% of the bill = [tex]\frac{15}{100}[/tex] × 51.19

∴ 15% of the bill = 0.15 × 51.19

∴ 15% of the bill = $7.6785

→ Substitute it in the total they paid

∵ The total they paid = 51.19 + 7.6785

∴ The total they paid = $58.8685

∴ The total they paid was $58.8685
