If you have a positive numerator but then a negative denominator while doing slope is it a Negative or Positive slope?

Answers

Answer:

Step-by-step explanation:

If either the numerator or a denominator in a fraction is negative, the slope if negative. However, if both the numerator and denominator are negative, it is positive.

The sign of the slope depends on the sign of the numerator and the denominator.

What is the slope of a line?

The slope of a line is given by the ratio of the change in the y-coordinate to the change in the x-coordinate between any two points on the line.

If the numerator is positive and the denominator is negative, then the overall sign of the fraction will be negative. Therefore, the slope will be negative.

For example, suppose the numerator is 3 and the denominator is -2. Then, the slope would be:

slope = 3/(-2) = -1.5

This means that the line has a negative slope, which indicates that the line is decreasing as it moves from left to right.

Thus, the slope of a line is negative if it is sloping downwards from left to right, and positive if it is sloping upwards from left to right.

A store clerk has 45 shirts to pack in boxes. Each box holds 6 shirts. What is the fewest boxes the clerk will need to pack all of the shirts?

Answers

Answer:

Answer- 8 cause 6 x 7 =42 he would need another on

Step-by-step explanation:

Answer:

8 boxes.

Step-by-step explanation:

We have to find out how many times 6 goes into 45.

45/6 = 7.5

Unfortunately, you can't have half a box. To correct this and be able to find the fewest amount of boxes, you simply round to the nearest whole number.

In this case, since the max amount of shirts that can fit in a box is 6, you must round up.

7.5 rounded up is 8.

The fewest amount of boxes you need is 8.

What is a complex number?

Complex numbers are helpful in finding the square root of negative numbers.

A complex number is the sum of a real number and an imaginary number.

The general form of a complex number is a + ib where the first part a called real and the ib is called imaginary.

If we solve x² + 1 = 0 ⇒ x = √(-1) which is called as iota(i).

Bar of complex number = replace i (iota) with - i (iota)

since z = 12 + i

So,

z bar = 12 - i

So 12 - i will be the correct answer to the given question.
