whats the product of 3x(-6)?

-98-31 can also be written as

(-98) + (-31)

We know 98+31=129

Therefore -129

The student's question about '-98 - 31' refers to simple subtraction, not the additive inverse property. Subtracting 31 from -98 provides the answer, -129.

The student asked how to solve the expression -98 - 31 using the additive inverse property. The additive inverse property states that: for any number 'a', there is a number '-a' such that: 'a + -a = 0'. Applying this property, if you were to add 98 to -98, it would give 0. However, the question asks for -98 - 31. This doesn't require the additive inverse property, but simple subtraction. Subtract 31 from -98 to get -129.

In this flowchart proof, we utilised the Corresponding Angles Postulate to conclude that line c is parallel to line d. Given that line a is parallel to line b, and angle 7 is congruent to angle 10, we can say that corresponding angles on line c and line d are also congruent, hence proving line c is parallel to line d.

For this flowchart proof, we will use the idea of corresponding angles and the postulate that if a transversal intersects two lines and the corresponding angles are congruent, then the lines are parallel.

[tex]|n-3|=5\iff n-3=5\ \vee\ n-3=-5\qquad|\text{add 3 to both sides}\\\\n=8\ \vee\ n=-2[/tex]

The solution for the equation |n-3|=5 is n=8, -2. These two points, when graphed on a number line represent the solution set.

In Mathematics, the absolute value of a number can have two possible solutions because it represents the distance from zero, and distance is always positive. To solve the equation |n-3|=5, we need to break it down into two separate equations.

When the term inside the absolute value (n-3 in this case) is positive, the equation is simply n-3=5. Solving for n gives n=8.

When the term inside the absolute value is negative, the equation is -(n-3) = 5, or equivalently, 3-n=5. Solving for n in this case gives n=-2.

So the solution set for n is {8, -2}. To graph the solution set on a number line, draw a number line from -3 to 9 and put closed dots at n=-2 and n=8.

The addition property of equality is the idea we can add some number to both sides of an equation. You must add the same number to both sides to keep things balanced.

It's asking "what number can we add to both sides of this equation so that we isolate x?"

Think of 20+x as x+20. We can rearrange terms since adding in any order doesn't matter (eg: 2+3 = 3+2 = 5)

So we really have this equation: x+20 = 25

We can add -20 to both sides to cancel out the +20 on the left side

x+20 = 25

x+20+(-20) = 25+(-20) ...... add -20 to both sides

x = 5

This is the exact same as subtracting 20 from both sides. So 5 will go where x is, meaning that 20+x = 20+5 = 25

Law of detachment is used when you have a conditional statement and another statement that matches the hypothesis of the conditional. ... Law of syllogism is used when you have two conditionals and the hypothesis of one matches the conclusion of the other.

Final answer:

In geometry, the law of syllogism allows for the combination of two conditional statements to reach a conclusion, while the law of detachment allows us to derive a conclusion from a known hypothesis and a conditional statement.

Explanation:

The Law of Syllogism and Detachment in Geometry

Both the law of syllogism and the law of detachment are forms of deductive reasoning used in geometry. The law of detachment is a process where we derive a conclusion from a single conditional statement and its hypothesis. For example, if we have a statement 'If a figure is a square, then it has four equal sides', and we know that a given figure is a square, we can deduce that this figure has four equal sides.

The law of syllogism, on the other hand, allows us to combine two conditional statements to derive a new conclusion. If we have two true statements, such as 'If an angle is acute, then it is less than 90 degrees' and 'If an angle is less than 90 degrees, then it is not a right angle', we can then conclude that 'If an angle is acute, then it is not a right angle'.

These laws form the backbone of logical reasoning in mathematics, allowing us to connect premises to reach valid conclusions and build upon established theorems and properties in geometry.

The range of a graph is the high-and-low points of the graph on the y-axis.

The high point looks like it is at y = 5. The low point appears at y = - 9

Option D is your answer.

Answer:

The range is:

 -9≤y≤5

Step-by-step explanation:

We have to find the range of the graphed function.

Here, the scale is of 2 units

The range is calculated as the values between the smallest value and the largest value

The smallest value graph attains is:  -9

and the largest value graph attains is: 5

Hence, the range is:

f ( 5 ) = 20 - 11

f(5 ) =  9

therefore f ( 5 ) = 9

Answer:

Insert a number into the x,

the middle column, you just substitute,

and the last column, you enter what x and y is.

Step-by-step explanation:

For example,

if x was 5, I would write 5 under the column,

under the y=2x+5 column, you would write y=2*5+5,

and under the last column you would write (5, 15)

2x+3=5

Subtract 3 both sides

2x=5-3

Simplify

2x=2

Divide 2 each side

X= 2/2

Evaluate

X=1

Step-by-step explanation:

The answer would be 230 2/3, because to get the perimeter you have to add all the sides together, 60 5/6 + 59 1/3 + 56 1/6 + 54 1/3 = 230 2/3

The correct perimeter of the figure is 230 2/3 ft. Here option C is correct.

The perimeter of the figure is the sum of the lengths of all its sides. To find the perimeter, we need to add the fractions given for each side.

We can do this by finding the common denominator and then adding the numerators. The common denominator for 3, 6 and 9 is 18. So, we have:

54 1/3 ft = 54 + 1/3 ft = 54 + 6/18 ft = 54 6/18 ft

56 1/6 ft = 56 + 1/6 ft = 56 + 3/18 ft = 56 3/18 ft

59 1/3 ft = 59 + 1/3 ft = 59 + 6/18 ft = 59 6/18 ft

60 5/6 ft = 60 + 5/6 ft = 60 + 15/18 ft = 60 15/18 ft

Now, we can add the fractions and simplify:

54 6/18 ft + 56 3/18 ft + 59 6/18 ft + 60 15/18 ft

= (54 + 56 + 59 + 60) + (6 + 3 + 6 + 15)/18 ft

= 229 + 30/18 ft

= 229 + 1 12/18 ft

= 229 + 1 2/3 ft

= 230 2/3 ft

Therefore, the perimeter of the figure is 230 2/3 ft. Here option C is correct.

To complete the square for [tex]x^2+2x-2=0[/tex].

We rewrite the equation to get

[tex]x^2+2x=2[/tex].

We now add [tex](1)^2[/tex] to both sides to get

[tex]x^2+2x+1^2=2+1^2[/tex].

The expression on the Left Hand Side of the equation is a perfect square.

So our equation becomes

[tex](x+1)^2=2+1[/tex]

This gives us,

[tex](x+1)^2=3[/tex]

We take square root of both sides to obtain,

[tex]x+1=\pm \sqrt{3}[/tex]

[tex]x=-1\pm \sqrt{3}[/tex]

We split the [tex]\pm[/tex] to obtain,

[tex]x=\sqrt{3}-1[/tex]

Answer:

x = √3 - 1 and x = -√3 - 1

Step-by-step explanation:

x^2  +2x - 2 = 0

To solve this equation, keep the variables on one side and constants on the other

x^2 + 2x = 2

Now to complete the square, divide the coefficient of x by 2:

2x ---> coefficient of x is 2

so 2/2 = 1

Now add the square of 1 to both the sides of the equation:

x^2 + 2x + (1)^2 = 2 + (1)^2

which makes it

(x + 1)^2 = 3

To solve it, take square root of both sides which gives

x = √3 - 1 and x = -√3 - 1
