yes because in a standard form that that equation is in, it'd be y=mx=b. the m represents the constant of proportionality or the rate of change. another name for it is the slope. in this case, the 9/5 is the m & c is x. meaning that, there is one & it is 9/5

Answer:

D. y= -4x +5

Step-by-step explanation:

To find the equation that is equivalent to y + 3 = -4(x - 2), we need to simplify and rearrange the equation to the standard y = mx + b form.

To find the equation that is equivalent to y + 3 = -4(x - 2), we need to simplify and rearrange the equation to the standard y = mx + b form. Here are the steps:

Therefore, the equation that is equivalent to y + 3 = -4(x - 2) is -4x + y = 5.

Step-by-step explanation:

[tex]\text{The product of the number and its reciprocal gives us 1.}\\\text{Reciprocal of }\ \dfrac{5}{2}\ \text{is equal}\ \dfrac{2}{5}.\\\\\dfrac{5}{2}\times\dfrac{2}{5}=\dfrac{5\!\!\!\!\diagup}{2\!\!\!\!\diagup}\times\dfrac{2\!\!\!\!\diagup}{5\!\!\!\!\diagup}=\dfrac{1}{1}\times\dfrac{1}{1}=1\times1=1[/tex]

Answer:

No

Step-by-step explanation:

For the relation to be a function

Each value of x from the domain ( values on left ) must map to exactly one unique value of y in the range ( values on the right )

Here x = 0 → 0 and 1 ( that is 2 values from the range )

Thus this does not represent a function

because the ratio of 98÷10=9.8

when we did the ration of 1078÷110=9.8

we can say that both ratio is same.

Answer: [tex]\frac{98}{10}[/tex] ; x = 110

Step-by-step explanation:

Since the ratio of weight to mass is constant , it implies:

[tex]\frac{490}{50}[/tex] = [tex]\frac{1078}{x}[/tex]

490x = 1078 X 50

490x = 53900

x = 53900/490

x = 110

Therefore the ratio of weight to mass will be :

1078/110

98/10

The time to make the taste to half is 4.265 s.

Step-by-step explanation:

Given:

Initial value of the taste is, [tex]Q_0=1[/tex]

Therefore, the quality of taste over time 't' is given as:

[tex]Q(t)=Q_0(0.85)^t\\Q(t)=1(0.85)^t[/tex]

Now, when the taste reduces to half, [tex]Q=0.5[/tex]

Therefore,

[tex]0.5=1(0.85)^t[/tex]

Taking natural log on both the sides, we get:

[tex]\ln(0.5)=\ln(0.85)^t\\\ln(0.5)=t\ln(0.85)\\t=\frac{ln(0.5)}{\ln(0.85)}=4.265\ s[/tex]

Therefore, the time to make the taste to half is 4.265 s.

Answer:This can be checked by the following steps;

Step-by-step explanation:

The pair (1,2) is a solution to the inequality 6x - y > 3 because when these values are substituted into the inequality, the result is 4 > 3, which is a true statement.

The question is asking if the pair of numbers (1,2) is a solution to the inequality 6x - y > 3. We can evaluate this by substituting the pair of values (1, 2) into the inequality in place of x and y. This gives us 6*1 - 2 > 3, or 6 - 2 > 3, which simplifies to 4 > 3. Since 4 is indeed greater than 3, we can conclude that the pair (1,2) is a solution to the inequality 6x - y > 3.

Using the rational exponent property, an equivalent expression for[tex]\(x^{3/4}\[/tex]  can be written as[tex]\(\sqrt[4]{x^3}\).[/tex]

The rational exponent property states that for any real number a and positive integer[tex]\(n\), \(a^{m/n} = \sqrt[n]{a^m}\)[/tex] . Applying this property to the given expression[tex]\(x^{3/4}\[/tex] ), where (m = 3) and (n = 4), we can rewrite it as [tex]\(\sqrt[4]{x^3}\)[/tex] . This is derived by taking the fourth root of [tex]\(x^3\),[/tex]  which is equivalent to raising [tex]\(x^3\)[/tex] to the power of[tex]\(1/4\).[/tex]

To further understand this, consider the original expression [tex]\(x^{3/4}\).[/tex] This represents the fourth root of [tex]\(x^3\)[/tex] , as the numerator 3 indicates the power to which x is raised, and the denominator 4 indicates the root. Expressing it as [tex]\(\sqrt[4]{x^3}\)[/tex] provides a clearer representation of the same mathematical concept, emphasizing the fourth root of [tex]\(x^3\).[/tex]

In mathematical notation, the rational exponent property is a useful tool for simplifying expressions involving fractional exponents. It allows us to transform expressions between radical form and exponent form, providing flexibility in mathematical manipulations and aiding in the understanding of the underlying concepts.

The solution of inequality would be -

c ≥ 1.95

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. There are two types of inequalities namely strict and slack inequalities.

We have the following inequality -

20 ≥ −3.2(c − 4.3)

It is given that -

20 ≥ −3.2(c − 4.3)

−3.2(c − 4.3) ≤ 20

-3.2c + 13.76 ≤ 20

-3.2c ≤  20 - 13.76

-3.2c ≤  6.24

c ≥ 1.95

Therefore, the solution of inequality would be -

c ≥ 1.95

Answer:

(2, 120° )

Step-by-step explanation:

To convert from rectangular to polar form, that is

(x, y) → (r, Θ ), use

r = [tex]\sqrt{x^2+y^2}[/tex]

Θ = [tex]tan^{-1}[/tex]( [tex]\frac{y}{x}[/tex])

here (x, y ) = (- 1, [tex]\sqrt{3}[/tex])

r = [tex]\sqrt{(-1)^2+(\sqrt{3} }[/tex] )^2

  = [tex]\sqrt{1+3}[/tex] = [tex]\sqrt{4}[/tex] = 2

Θ = [tex]tan^{-1}[/tex]([tex]\sqrt{3}[/tex]) = 60° ← related acute angle

Note (- 1, [tex]\sqrt{3}[/tex]) is in the second quadrant so Θ must be in the second quadrant.

Θ = 180° - 60° = 120°

(- 1, [tex]\sqrt{3}[/tex]) → (2, 120°)

Answer:

The total number of students actually went for skiing is 0.75 times the total students .

Step-by-step explanation:

Given as :

Some Students were surveyed about their wither break plans.

The percentage of students who actually did not go for skiing = 25 %

So , The percentage of students who actually go for skiing = 100 % of students - 25 %

I.e The percentage of students who actually go for skiing = 75 %

Let The total number of students = x

So, out of x students , The The percentage of students who actually go for skiing = 75 % of the total students

I.e The The percentage of students who actually go for skiing = 75 % of x

Or, The The percentage of students who actually go for skiing = 0.75 × x

So, The number of students for skiing = 0.75 x

Hence The total number of students actually went for skiing is 0.75 times the total students . Answer

Answer:

Number of songs played in commercial are 7 and  Number of songs played in movie are 5.

Step-by-step explanation:

Let Number of songs played in commercial be x

and Number of songs played in movie be y.

Total number of songs played =12

Hence,

[tex]x+y=12\ \ \ \ equation \ 1[/tex]

Also

Cost for songs played in commercial = $50

Cost for  songs played in movie = $130

Total Money earned = $1000

Hence,

[tex]\$50x+\$130y=\$1000[/tex]

Dividing by 10 on both side we get;

[tex]\$5x+\$13y=\$100\ \ \ \ equation \ 2[/tex]

Now multiplying equation 1 by 5 we get;

[tex]5x+5y=60 \ \ \ \ equation \ 3[/tex]

Now Subtracting equation 3 from equation 2 we get;

[tex](5x+13y=100)- (5x+5y=60)\\8y=40\\y=\frac{40}{8}=5[/tex]

y = 5

x + y = 12

x + 5 = 12

x = 12 - 5

x = 7

Hence, Number of songs played in commercial are 7 and  Number of songs played in movie are 5.

y = 17.5 when x = 5

Step-by-step explanation:

When two variables are in direct proportion i.e. change in one variable causes change in other variable it can be expressed mathematically as:

y∝x

when the proportionality symbol is removed a proportionality constant is introduced

So,

[tex]y = kx[/tex]

Putting y = 7 and x = 2

[tex]7 = k * 2\\k = \frac{7}{2}\\k = 3.5[/tex]

So the expression will be:

[tex]y = 3.5x[/tex]

Now putting x = 5

[tex]y = 3.5 * 5\\y = 17.5[/tex]

Hence,

y = 17.5 when x = 5

Step-by-step explanation:

The function would be h = 270 - 2.5s, where h is the height (in feet) and s it the time (in seconds) that has passed.

The 270 represents the initial value, which is given. We are told that the initial height of the block is 270 feet.

2.5s represents the feet that it has descended. We know the block is lowered at a rate of 2.5 feet per second. Multiplying this by s, the time, will give us how much it has descended.

The height at any point is can be given by function f(s) = 270 - 2.5s.

Given to us,

concrete block top height, H = 270 feet,

speed of the block, v = 2.5 feet/second,

We know that  [tex]\rm \bold{speed = \dfrac{Distance}{Time} }[/tex],

thus,  [tex]\rm \bold{Distance = speed\times Time}[/tex]

So, we can write, height (distance from the top height) covered is "s" seconds as,

[tex]\bold{h = v \times s}=\bold{2.5\times s} = \rm \bold{2.5s}[/tex]

therefore, we can write,

Height at any point = Top height - height covered

                                 = 270 - 2.5s

Hence, the height at any point is can be given by function f(s) = 270 - 2.5s.
