a positive number multiplied or divided by a negative number is always
negative or positive

Answers

Answer 1
It is always negative. For example, -1 times 2 is -2
Answer 2

Answer:

Negative

Step-by-step explanation:

Think about it this way, you cannot do something positive and then do something negative and it still be positive. You cannot do something negative and then do something positive for it to be positive. But you can do something positive and do something else positive for it to remain positive the same with negative. Therefore the answer is "negative."

Rules:

Positive ÷ Negative = Negative

Positive × Positive = Positive

Negative ÷ Negative = Positive

Hope this helps.

[Help Asap] For each ordered pair, determine whether it is a solution to the system of equations.

Answers

Answer:

(-4,-4)

Step-by-step explanation:

6x - 7y = 4

6(-4) - 7(-4) = 4

-24 + 28 = 4

4 = 4 This is correct to the first equation.

Now let us try the second equation.

-5x + 3y = 8

-5(-4) + 3(-4) = 8

20 - 12 = 8

8 = 8 This is also correct to the second equation.

Hope this helps, thank you !!

A plant is already 54 centimeters tall, and it will grow one centimeter every month. The plant's height, H (in centimeters), after M months is given by the following.
What is the plant's height after 13 months?

Answers

Answer:

67 cm

Step-by-step explanation:

We are given the initial height of the plant let's call it H.

H = 54 cm. This is the original height of the plant at M(months) = 0.

We are given that it grows at 1 cm/month. This is the rate of growth.

Rate = 1

Time (M) is given in Months.

So when M = 0, H = 54

Let's say M = 1, That is one month has passed. In this time the plant's height would have increased by 1 cm. So our plant's height would be H = 54+1 = 55 cm.

When Two months have passed our plant's height would be H = 54 + 2 = 56 cm , since every month our plant gains 1 cm in Height, we can make a fuction for this.

H = 1M + 54.

Now we just plug in 13 for M, to get 13 months.

H = 13 + 54

H = 67 cm

So our plant would be 67 cm in height after 13 months.

What is the Area and Perimeter for tbe rectangle?

Answers

Given :-

length of rectangle = ( 4n-5 )

breadth of rectangle = ( 3n-2)

To find :-

Area and perimeter of rectangle.

solution :-

by the question ,

We know the area of rectangle = length × breadth

Area = (4n -5) (3n-2)

[tex] = {12n}^{2} - 8n - 15n + 10[/tex]

[tex] = {12n}^{2} - 23n + 10[/tex]

now ,

perimeter = 2 ( length + breadth (

= 2 ( 4n-5 + 3n-2)

= 2 ( 7n-7)
