Linear equations are equations that have constant slopes

The linear equation that represents the table is (a) y = 7x +4

Start by calculating the slope (m) using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{-10 +17}{-2 +3}[/tex]

Simplify

[tex]m = \frac{7}{1}[/tex]

[tex]m = 7[/tex]

The equation is then calculated as:

[tex]y = m(x -x_1) + y_1[/tex]

So, we have:

[tex]y = 7(x +2) -10[/tex]

Open the brackets

[tex]y = 7x +14 -10[/tex]

[tex]y = 7x +4[/tex]

Hence, the linear equation that represents the table is (a) y = 7x +4

Step-by-step explanation:Sorry your answer is late

Answer:

41 and 205

Step-by-step explanation:

Since the smaller number is 1/5 the larger number, the distance between the numbers is 4/5 of the larger number because (5/5 - 1/5 = 4/5).

You are given the difference, so first find the smaller number by dividing by 4:

164 = (4/5)(larger number)

164 = 4(smaller number)

41 = smaller number

Now, just multiply by 5, since 41 is 1/5 of the larger number:

41 * 5 = 205 = larger number

Optionally, check the answer by testing the difference:

205 - 41 = 164

Answer:

3^3

The answer is a.3^3

The scale factor k for the sphere's volume in order to arrive at the volume of the new sphere is 3^3, the correct option is A

Suppose the initial measurement of a figure was x units.

And let the figure is scaled and new measurement is of y units.

Since the scaling is done by multiplication of some constant, that constant is called scale factor. Let that constant be 's'.

Then we have:

[tex]s \times x = y\\s = \dfrac{y}{x}[/tex]

Thus, scale factor is the ratio of the new measurement to the old measurement.

Given;

Radius is multiplied by 3

In order to arrive at the volume of new sphere the factor must be greater or equal to 3

So,

Scale factor=x*k

=3^3

Therefore, the scale factor k will be 3^3

The revenue function is the sum of the cost and profit functions

The total amount of revenue on Sunday is $59.17

The function for the number of roses is given as:

[tex]N(d) = 6d + 25[/tex]

The price per rose is given as:

[tex]P(d) = 0.02d^2 - 0.04d + 0.49[/tex]

On Sunday, the value of d is 6.

So, we start by calculating N(6) and P(6)

[tex]N(d) = 6d + 25[/tex]

[tex]N(6)= 6 * 6 + 25[/tex]

[tex]N(6)= 61[/tex]

[tex]P(d) = 0.02d^2 - 0.04d + 0.49[/tex]

[tex]P(6) = 0.02 * 6^2 - 0.04 * 6 + 0.49[/tex]

[tex]P(6) = 0.97[/tex]

The total amount of revenue is then calculated as:

[tex]R(d) = N(d) * P(d)[/tex]

Substitute 6 for d

[tex]R(6) = N(6) * P(6)[/tex]

So, we have:

[tex]R(6) = 61 * 0.97[/tex]

[tex]R(6) = 59.17[/tex]

Hence, the total amount of revenue is $59.17

Answer:

1107.4

Step-by-step explanation:

Took Test.

The sum of 14 terms of the arithmetic sequence having the first term, a₁ = 18, and the constant difference, d = 9.4 is given as S₁₄ = 1107.4. Hence, the first option is the right choice.

An arithmetic sequence is a special sequence where every term is the sum of the previous term and a constant.

The sum of an arithmetic sequence having n-terms, with the first term being a, and the constant difference being d is given by the formula:

Sₙ = (n/2){2a + (n - 1)d}, where Sₙ is the sum of n-terms.

In the question, we are asked to find the sum of 14 terms for the arithmetic sequence, where the first term, a₁ = 18, and the constant difference, d = 9.4.

We know that the sum of an arithmetic sequence having n-terms, with the first term being a, and the constant difference being d is given by the formula:

Sₙ = (n/2){2a + (n - 1)d}, where Sₙ is the sum of n-terms.

Thus, substituting n = 14, a = 18, and d = 9.4 in the above formula, we get:

S₁₄ = (14/2){2(18) + (14 - 1)(9.4)},

or, S₁₄ = 7{36 + 122.2},

or, S₁₄ = 7*158.2,

or, S₁₄ = 1107.4.

Thus, the sum of 14 terms of the arithmetic sequence having the first term, a₁ = 18, and the constant difference, d = 9.4 is given as S₁₄ = 1107.4. Hence, the first option is the right choice.
