Please help me with my question!

<h2>Positive and Negative Numbers on the Number Line</h2>

When we add two negative numbers, the result will be negative.

When we add a negative and a positive number, the result can be positive, negative, or equal to zero.

Take the absolute values of both numbers (disregard their signs). If the number that was positive is greater, then the result will be positive.
If the number that was negative is greater, then the result will be negative.
If the two numbers are equal, then the result will be 0.

When we add two positive numbers, the result will be positive.

<h2>Solving the Question</h2><h3><em>j</em> + <em>k</em></h3>

These are both negative numbers. We know this because they are both to the left of 0. When we add two negative numbers, we will get a result that is less than 0.

<em>Less than 0</em>

<em />

<em>k</em> is a negative number while <em>n</em> is a positive number.

Notice that on the number line, <em>k</em> and <em>n</em> appear to be at a equal distance away from 0. This means that if we were to take their absolute values, they would be equal.

This means that adding <em>k</em> and <em>n</em> would result in an answer of 0.

<em>Equal to 0</em>

<em />

<em>m</em> is a negative number while <em>n</em> is a positive number.

Notice that on the number line, <em>n</em> appears to be further away from 0 than <em>m</em> is. <em>m</em> is very close to 0.

This means that the absolute value of <em>n</em> would be greater than that of <em>m</em>. The result would therefore be positive

<em>Greater than 0</em>

<em />

Both these numbers are negative. Adding them would produce a negative result.

<em>Less than 0</em>

A spinner is divided into four equal sections that are numbered 2, 4, 7, and 9. The spinner is spun twice.How many outcomes have

shusha [124]

The spinner is divided into four equal sections: 2, 4, 7, 9. This represents 4 possibilities

If the spinner is spun twice, the sample space is:

$\text{Sample space = 4}^2\text{ = 16}$

For product less than 30, the number of outcomes is shown below:

The number of outcomes that have a product less than 30 = 10

The sample space that shows possibilities of an odd number combination:

The number of outcomes that contains at least one odd number = 12

The number of outcomes that have a product less than 30 and contain at least one odd number is shown below. These outcomes are outcomes circled in both cases shown above,

The outcomes circled represents the number of outcomes that has a product less than 30 and contains at least one odd number

Answer: 6 (option B)

Solve the problem. give that f(x)=4x²-7x;find all values of a such that f(a)=15 HELP!!!

joja [24]

$4x^2-7x=15\\
4x^2-7x-15=0\\
4x^2-12x+5x-15=0\\
4x(x-3)+5(x-3)=0\\
(4x+5)(x-3)=0\\
x=-\frac{5}{4} \vee x=3$

Is the statement {0}=ø true or false

Schach [20]

Answer:

False

Step-by-step explanation:

This statement is false

{0}=ø

The first parts {0} says there is a zero in the set

The second item says it is an empty set
