The linear function is y = 3x + 6. Then the rate of change of the linear function will be 3.

The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.

The linear equation that is passing through the points  (2,9) and (-1,3).

Then we have

y - 3 = [(3 - 9)(-1 - 2)] (x + 1)

y - 3 = (-6) / (-2) (x + 1)

y - 3 = 3x + 3

    y = 3x + 6

Then the rate of change of the linear function will be

y' = 3

Answer:

3, 5, 7

Step-by-step explanation:

Let the first of the three positive consecutive odd numbers be [tex]x[/tex].

Now, the second odd number = [tex]x+2\\[/tex]

And, the third odd number = [tex]x+4[/tex]

As per question statement, the multiplication of the first and third odd number is 9 lesser than the 6 times the second integer.

Writing the equation, we get:

[tex]x(x+4) = 6(x+2)-9\\\Rightarrow x^{2} +4x=6x+12-9\\\Rightarrow x^{2} +4x-6x = 3\\\Rightarrow x^{2} -2x - 3=0\\\text{Solving the above equation by factorization method:}\\\Rightarrow x^{2} -3x +x - 3=0\\\Rightarrow x(x -3) + 1(x - 3)=0\\\Rightarrow (x -3) (x+ 1)=0\\\Rightarrow x =3, -1[/tex]

As, we got a quadratic equation, so we have two solutions here.

One is positive integer and other one is negative.

So, solution is [tex]x=3[/tex]

First number is 3.

Second number is 3 + 2 = 5

Third number is 5 + 2 = 7

Answer: 0.2d

Step-by-step explanation: For calculating the 20% tip of the cost in dollars of a dinner, simply multiply 0.2 by the cost of dollars of a dinner. 0.2 represents 20% and by using the variable "d" to represent the cost of the dinner, you can write this equation: 0.2d.

Answer:

So the first term is two so you start on the second term. 15,28,41

An arithmetic sequence having first term 2 and a common difference of 13 then the next terms are 15, 28 and 41.

An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference

d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.

In a geometric sequence numbers are written in the same constant ratio(r).

It means every next number is a multiple of a common constant and the previous number.

r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.

Given, An arithmetic sequence having first term 2 and a common difference of 13.

Therefore the next terms are (2+13), (2 + 2×13), (2 + 3×13).

= 15, 28, and 41.

Answer:

I'm assuming the 2 after 9t and -2t means squared.

7t² + 12t + 4

Step-by-step explanation:

To simplify the expression we should combine like terms. Like terms are terms with same variables and powers.

Let's start with 9t² and -2t² since they have the same variable and power of t². To combine them we should add them together which would be: 9t² + (-2t²) = 9t² - 2t² = 7t²

Next we can combine 7t and 5t since they have the same variable and power of t. 7t + 5t = 12t

4 doesn't have any like terms so we leave it as it is.

Lastly we add all of our terms: 7t² + 12t + 4

Answer:

Equation: x° + x° + (x + 10)° + 59° = 360°

Solution: x = 97

Step-by-step explanation:

The sum of the interior angles of a quadrilateral = 360°

Therefore:

x° + x° + (x + 10)° + 59° = 360°

Solve for x

x + x + x + 10 + 59 = 360

Add like terms

3x + 69 = 360

Subtract 69 from each side

3x = 360 - 69

3x = 291

Divide both sides by 3

x = 97

Answer:

(1.985, 15.815)

Step-by-step explanation:

Given that:

Sample size (n) = 20

Standard deviation (s) = 11.986

Mean (m) = 8.9

α = 99%

Using the relation :

Confidence Interval = Mean ± Error

Where ;

Error = Zcritical * standard deviation / sqrt(n)

Zcritical at 99% = 2.58

Hence,

Error = 2.58 * (11.986/sqrt(20))

Error = 2.58 * 2.6801510

Error = 6.91478958

Hence,

Lower boundary = 8.9 - 6.91478958 = 1.98521042

Upper boundary = 8.9 + 6.91478958 = 15.81478958

Line segments DE and BC are not parallel because they divide the opposite side of the triangle at different ratios.

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

Given, Line segment AD is 4 units and line segment DB is 2 units.

∴ Line segment AD is (4/2) = 2 times greater.

On the other hand line segment, AE is 9 units and line segment EC is 5 units.

∴ Line segment AE is (9/5) = 1.8  times greater.

Line segments BC and DE should have been parallel if they had the same ratios.

Answer:

48

Step-by-step explanation:

Hi!

Remember, the sum of the angles on a straight angle is 180 degrees. Additionally, the sum of the measures of a triangle are 180 degrees.

Now, let's label the angles of the given triangle.

<DCE = y and <CDE=x

x+y+92=180

x+y= 88

Now, y+140 = 180 --> y= 40

x+40 = 88

x=48

The answer is 48 degrees.
