The statement can be proved by the law of syllogism.

A formal logical framework used to infer a conclusion from a series of premises is referred to as a syllogism, also known as a rule of inference.

The law of syllogism in conditional statement is given as:

if p then r and if r then q , then we can state that if p then q , where p , q, and r are statements.

Now in the given conditional statements we can write it as:

let p = You go camping

r = you will need a flashlight

q = you will need extra batteries.

Now it is given the if p then r and again if r then q , so by using the law of syllogism we can state that if p then q , that is

The equation x = 2

is the slope-intercept form of the line passing through the points (2,-1) and (2,6)

It is given that, the line is passing through two points (2, -1) and (2, 6)

The formula to find the equation of a line in two point form is

(y-y1) = [tex]\frac{y2 - y1}{x2 - x1}[/tex](x-x1)

where m = [tex]\frac{y2 - y1}{x2 - x1 }[/tex] is the slope of the line

Slope is the measurement of the level of steepness of the line

We need to find the Two- Point form of the line

Using the above formula we get, where

x1 = 2 , x2 = 2, y1 = -1, y2 = 6

m = [tex]\frac{(6-(-1))}{(2-2)}[/tex]= [tex]\frac{7}{0}[/tex]

The equation of the line = (y-y1) = [tex]\frac{y2 - y1}{x2 - x1}[/tex](x-x1)

[y - (-1)] = [tex]\frac{7}{0}[/tex] (x - 2)

0. [y - (-1)] = 7(x-2)

7x - 14 = 0

x = 2

Hence, x =2 is the slope-intercept form of the line passing through the points (2,-1) and (2,6)

The measure of the angle JL is 33 degrees

A bisection is a line that divides an angle into two equal portion. Using the addition postulate below:

<JKM = <JKL + <LKN + <NKM

If the line KN bisects <LKM then <LKN = <NKM = 22 degrees

Substitute the given parameters

<JKM = <JKL + <LKN + <NKM

77 = <JKL + 22 + 22

77 = <JKL + 44

<JKL = 77 - 44

<JKL = 33 degrees

The properties used in the the simplification of the expression is:

step 1: Inverse multiplication property

step 2: Commutative property

step 3: Associative property

step 4:  Commutative property

step 5: Identity property

Given the expression is:

1 ÷ 2/3 × (₋5) × 3 ÷ (₋1/4)

step 1: 1 × 3/2 × (₋5)  × 3 × (₋4)

Inverse multiplication property is applied.

The reciprocal of a particular integer is referred to as the multiplicative inverse. It is employed to make mathematical expressions simpler. The word "inverse" denotes an opposing or opposed action, arrangement, position, or direction. A number becomes 1 when it is multiplied by its multiplicative inverse.

step 2: 1 × (₋4) × 3/2 × (₋5) × 3

Commutative property is applied.

Mathematical addition and multiplication operations are covered under the commutative property. In other words, adding or multiplying two integers does not change the outcome if the order or location of the numbers is changed.

step 3: 1 × [(₋4) × 3/2] × (₋5) × 3

Associative property is applied.

According to the associative feature of multiplication, the outcome of a multiplication problem is unaffected by the arrangement of the numbers in the problem's constituent parts.

step 4: 1 ×[-6] × (₋5) × 3

commutative property is applied.

step 5: (-6) × (₋5) × 3

Identity property is applied.

Multiplying 1 by any number yields the number itself, according to the Multiplicative Identity Property, commonly known as the Identity Property of Multiplication. This is because any time a number is multiplied by 1, it retains its identity and does not change.

Hence we have applied the above mentioned properties of multiplication.

The total weight of the two animals is 1.2 x 10^5 lbs

The given parameters are

Animal 1 = 5.36 x 104 lbs.

Animal 2 = 6.2 x 104 lbs

Rewrite the parameters properly

Animal 1 = 5.36 x 10^4 lbs.

Animal 2 = 6.2 x 10^4 lbs

The total weight of the two animals is calculated as

Total weight = Animal 1 + Animal 2

This gives

Total weight = 5.36 x 10^4 lbs + 6.2 x 10^4 lbs.

Factor out 10^4 lbs

Total weight = (5.36 + 6.2) x 10^4 lbs.

Evaluate the sum

Total weight = 11.56 x 10^4 lbs.

Rewrite as

Total weight = 1.156 x 10^5 lbs.

Approximate

Total weight = 1.2 x 10^5 lbs.
