Solving the problem as per a linear equation, it can be proved that q = r.

A linear equation is an algebraic equation in the form of y = mx+ b. The highest power of a variable in a linear equation is always 1. Such equations always form a straight line on the graph.

From equation 1 we can write,

2q - r = 4p.................(1)

or, 2q - 4p = r ( side switched ) ................(2)

Now, 2p = r

or, 4p = 2r and we know 2r = q

Hence, we can write 4p = q ...............(3)

If we put equation (3) in (1)

we will get, 2q - q = r

or, q = r

q = r is proved.

The stated logarithm equation log₇8 in changed by the Base Formula is logₓ8 - logₓ 7.

A logarithmic notation is one where variable x contains a logarithm.

The variable in an exponential equation is depicted by an exponent. To solve exponential equations, first see if both sides of the formula could be written as powers of the same number. If you can't, consider taking the common logarithm of both equation sides and solve the problem using property.

Now, as per the stated conditions;

The given equation is; log₇8

Apply the Base Rule and re-write the equation;

= logₓ8 / logₓ 7

This obtained equation can also be written on the form by applying product rule.

=  logₓ8 - logₓ 7

Therefore, the logarithm equation log₇8 in expressed by the Base Formula is logₓ8 - logₓ 7.

The equation 6 ⁸ = a + 1 in the logarithm form will be given as log ₆ ( a + 1 ) = 8 .

Logarithms are another form of  exponents.

For example, we know that 2 raised to which power is equal to 8,

this is expressed by the exponential form as follows 2³ = 8 is equal to log ₂ 8 = 3

Both equations describe the same relationship between the numbers 2, 3, 8 where 2 is the base and 3 is the exponent

The difference is that while the exponential form isolates the power 8,the logarithmic form isolates 3

So by writing given equation in logarithmic form we get -log₆ ( a + 1 ) = 8.

Therefore, the equation 6 ⁸ = a + 1 in the logarithm form will be given as log ₆ ( a + 1 ) = 8 .

The required dimension of the longer side of the fencing is 18 ft.

As given in the question, there is an 18-ft fence on one side of a rectangular garden. the gardener has 43 ft of fencing to enclose the other three sides.

Perimeter is the measure of the figure on its circumference.

Here,
Total length of the fencing = 18 + 43
The total length of the fencing = 61
Perimeter of rectangle  = 2 length + 2 width
61 = 2 * 18 + 2 width
2 width = 61 - 36
2 width = 25
width = 12.5 ft

Thus, the required dimension of the longer side of the fencing is 18 ft.

An equation is an formula which equates two mathematical expressions.

We can solve equations by adding or subtracting same number from both sides or by diving both sides by same number (positive or negative)

[tex]\frac{-8}{3} x+4(x+\frac{9}{4} )= \frac{-2}{3} (x+\frac{12}{8} )+3\\[/tex]

After Opening brackets, we get:

[tex]\frac{-8}{3} x+4x+4(\frac{9}{4} )= \frac{-2}{3} x-\frac{2}{3} *\frac{12}{8} +3[/tex]

[tex]\frac{-8}{3} x+4x+9= \frac{-2}{3} x-1 +3[/tex]

Subtracting 9 from both sides, we get:

[tex]\frac{-8}{3} x+4x+9-9= \frac{-2}{3} x-1 +3-9\\\frac{-8}{3} x+4x= \frac{-2}{3} x-7[/tex]

Moving all terms of x on to one side:

Step-by-step explanation:  3 over 9 = .333 repeating which is greater then .22 and lower then 33

Answer:

0.25

Step-by-step explanation:

group like terms: 0.42b+9.14b-8.3=-5.91

add similar elements: 9.56b-8.3=-5.91

multiply both sides by 100: 956b-830=-591

add 830 to both sides: 956b-830+830=-591+830

simplify: 956b=239

divide each side by 956: you know what that looks like

simplify: b=1/4

convert to decimal: 0.25

Answer:

b = 0.25

Step-by-step explanation:

Given:

[tex]\sf 0.42b - 8.3 + 9.14b = -5.91[/tex]

Collect like terms:

[tex]\implies\sf 0.42b+ 9.14b - 8.3 = -5.91[/tex]

Combine like terms:

[tex]\implies \sf 9.56b - 8.3 = -5.91[/tex]

Add 8.3 to both sides:

[tex]\implies \sf 9.56b - 8.3+8.3 = -5.91+8.3[/tex]

[tex]\implies \sf 9.56b=2.39[/tex]

Multiply both sides by 100:

[tex]\implies \sf 9.56b \times 100=2.39 \times 100[/tex]

[tex]\implies \sf 956b=239[/tex]

Divide both sides by 956:

[tex]\implies \sf \dfrac{956b}{956}=\dfrac{239}{956}[/tex]

[tex]\implies \sf b=\dfrac{239}{956}[/tex]

Write 956 as 4 × 239:

[tex]\implies \sf b=\dfrac{1 \times 239}{4 \times 239}[/tex]

Cancel the common factor 239:

[tex]\implies \sf b=\dfrac{1}{4}[/tex]

[tex]\implies \sf b=0.25[/tex]

The value of logarithmic expression x log₄m+1/y log₄n - log₄p is log₄(m^x  * n^1/4)/p.

By considering the given logarithmic expression

x log₄m+1/y log₄n - log₄p

log₄m^x+  log₄n^1/4- log₄p

log₄(m^x  * n^1/4)- log₄p

log₄(m^x  * n^1/4)/p

The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number.

Based on the logarithm base, the logarithmic functions are broadly divided into two types. There are common and natural logarithms. Common logarithms are based on the number 10, while natural logarithms are based on the base "e." The power to which a number must be raised in order to obtain another number is known as a logarithm (see Section 3 of this Math Review for more about exponents).

It is 100 million because if you forget the K which means three zeros, it would be like this. 100000000. After three digits, you put a comma, so it would be 100,000,000.

No, it is not as a result of all whole numbers are integers, thus there's no number that's not associate degree whole number.

The whole numbers area unit the numbers while not fractions and it's a group of positive integers and nil. it's diagrammatical by the image “W” and also the set of numbers area unit . Zero as a full represents nothing or a null worth.These numbers area unit positive integers as well as zero and don't embody aliquot or decimal elements (3/4, 2.2 and 5.3 don't seem to be whole numbers).

Calvin is incorrect. He should add 2 to each side not multiply each side by 2.

The correct answer is an option (C)

For given question,

Let l be the length of the rectangle and w be the width of the rectangle.

Assume that l = 10 units and w = 4 units

The perimeter of the rectangle is,

P = 2(length + width)

So, for above values the perimeter of the rectangle would be,

⇒ P1 = 2×(10 + 4)

⇒ P1 = 28 units

The length of each side is increased by 2 units.

so, l = 12 and w = 6 units

Then the perimeter of the rectangle would be,

P2 = 2(12 + 6)

P2 = 36 units

According to Calvin, if the length of each side of rectangle is increased by 2 units, the perimeter of the rectangle would double.

But from P1 and P2 we can clearly observe that, Calvin is incorrect.

Calvin possibly double the each side of the rectangle instead of increasing by 2 units.

If he double each side then l = 20 and w = 8

The perimeter of the rectangle would be,

P3 = 2(20 + 8)

P3 = 56

From P1 and P3, the perimeter of the rectangle is doubled.

Therefore,  Calvin is incorrect. He should add 2 to each side not multiply each side by 2.
