What is the equation of a line, in general form, with a point (-3, 0) and an undefined slope? x + 3 = 0

1 answer:

6 0

x=-3

This is because when a line is vertical, then it has an undefined slope and so it must have a value for x only. This shows it must be x=-3.

Laura randomly pulled a marble from a bag and then replaced it.

marissa [1.9K]

Answer: C. 180 times

Step-by-step explanation:

From the 60 trials, the percentage of times Laura picked a green marble was:

= 100% - Percentage of times blue and red were picked

= 100% - 25% - 15%

= 60%

If these results were repeated with 300 trials, the number of times Laura would be expected to pick green would be:

= 60% * 300

= 180 times

C) Parbati buys a mobile for Rs 6,300 and sells it to Laxmi at 15% profit. How much

Leni [432]

Answer:

Rs. 7245

Step-by-step explanation:

Given parameters:

Cost price = Rs. 6300

Percentage profit = 15%

Unknown:

Selling price = ?

Solution:

If profit is made on a trade, the selling price is higher than the cost price.

Profit = Selling price - Cost price

To find the selling price simply;

Selling price =( 1 + $\frac{15}{100}$ ) x cost price

Selling price = 1.15 x 6300 = Rs. 7245

Answer:

Step-by-step explanation:

Take the area of the yard and subtract from it the area of the pool. In quadratic form, the area of the pool is

$2x^2-x-28$

Subtracting the area of the pool from the area of the yard:

$3x^2-14x-5-(2x^2-x-28)$

Since the negative in front of the parenthesis will change the signs inside:

$3x^2-14x-5-2x^2+x+28$

Combine like terms to get the area left after the pool goes in:

$x^2-13x+23$
