The equation to represent the relationship between  number of years and height of tree is y = 2.5x + 4

The tree was planted at 4 feet.

It will grow 2.5 feet each year.

x =  the number of years since the tree has been planted.

y = the projected height of the tree

Therefore, the relationships between x, the number of years since the tree has been planted, and y, the projected height of the tree can be represented as follows:

The equations is linear.

Hence, it will be in the format below

y = mx + b

where

y = 2.5x + 4

Therefore, the equation to represent the relationship is as follows:

Answer: Table 3,

x :  -9   -7    -5   -3    -1

y: -25   -21   -17  -13   -9

has same slope as line given equal to 2.

Step-by-step explanation:

Slope between two points having coordinates,  (x1, y1) (x2,y2) which lie in a coordinate plane is given by:

coordinate plane is given by:

                                = (y2 - y1) / (x2 - x1)

We can see table 1,

Then we can write,

                           = (-7 - (-9) ) / (-21 - (-25) )

                           = (-7+9) / (-21+25)

                           = 2/4

                           = 1/2

We can see table 2,

Then we can write,

                         = (7-9) / (-21 - (-25) )

                         = -2/-21+25

                         = -2/4

                         = -1/2

We can see table 2,

Then we can write,

                              =  (-21 - (-25) ) / (-7 - (-9) )

                              = (-21+25) / (-7+9)

                              = 4/2

                              = 2

Now, slope of line which passes through (0,-3) and (3,3) is

                              = (3 - (-3)) / 3-0

                              = 3+3/3

                              = 6/3

                              = 2

Table 3,

x :  -9   -7    -5   -3    -1

y: -25   -21   -17  -13   -9

has same slope as line given equal to 2.

From what i can see c will be in the middle so 14cm and d i cant see really but going off what i can see 3cm

Answer:

[tex]x = -8[/tex]

Step-by-step explanation:

Let [tex]x[/tex] be the integer, then the consecutive integer is [tex]x + 1[/tex]. "3 times the next consecutive integer" means we should multiply [tex]x + 1[/tex] (the consecutive integer) by 3, giving us [tex]3 ( x + 1)[/tex].

We are told that the sum of [tex]x[/tex] and [tex]3(x + 1)[/tex] gives -29. Therefore, we can build an equation.

The sum of [tex]x[/tex] and [tex]3(x + 1)[/tex] can be expressed as [tex]x + 3(x + 1)[/tex].

Therefore,

[tex]x + 3(x + 1) = -29 \text{ // Distribute 3(x + 1)}\\x + 3 \times x + 3 \times 1 = -29\\\to x + 3x + 3 = -29 \text{ // Simplify}\\\to 4x + 3 = -29 \text{ // Subtract 3 from both sides}\\4x + 3 - 3 = -29 - 3\\\to 4x = -32 \text{ // Divide by 4 on both sides}\\\frac{4x}4 = -\frac{32}4\\\to x = -8[/tex]

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

If she works 30 hours per week then

So, her weekly pay

=30*8.75

=262.5

Then her monthly pay

=4* 262.5

Answer: Option C. 6x+8=3(2x+4)

Step-by-step explanation:

Solution = S

No Solution = NS

( S ) A. 6x - 9 = 9x - 6

6x - 9 + 9 = 9x - 6 + 9

6x = 9x + 3

6x - 9x = 9x + 3 - 9x

-3x = 3

-3x/-3 = 3/-3

( S ) B. 6 - (2x+3) = -4 (x + 1 ) + 7

6 - (2x+3)

6 - 2x - 3

-2x + 3 = -4x + 3

-2x + 3 - 3 = -4x + 3 - 3

-2x = -4x

-2x + 4x = -4x +4x

2x = 0

2x/2 = 0/2

The linear equation in standard form that satisfies the given conditions is

x - y = -5

Given,

Points that the line passes through:

(x₁, y₁) = (4, -1)

(x₂, y₂) = (8, 3)

Let's find the slope of the line,

m = [tex]\frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex] = [tex]\frac{3-(-1)}{8-4}[/tex] = [tex]\frac{3+1}{4}[/tex] = [tex]\frac{4}{4}[/tex] = 1

Now, we can write the equation in point slope form:

y - y₁ = m(x - x₁)

y - (-1) = 1(x - 4)

y + 1 = x - 4

Add -1 to both sides.

y + 1 - 1 = x - 4 - 1

y = x - 5

Now, let's convert this to standard form.

Ax + By = C

Here,

y = x - 5

Add +5 to both sides.

y + 5 = x - 5 + 5

y + 5 = x

x - y = -5

Answer:

Step-by-step explanation:

So start with your parentheses, (8-5)(5-3). 8-5=3 and 5-3=2, and when two parentheses are next to each other they will be multiplied.

Example: 3(5-3)^2 ---> 3 x 2^2
Although this "^" means "to the power" so 2 to the power of 2 is 2 x 2=4

So putting it all together we get, (8-5)(5-3)^2 --> 3(5-3)^2 --> 3 x 2^2 [2x2=4] --> 3 x 4 = 12
Your final answer is 12!

Answer:

14.5 inches of snow, S=T(H)+B

Step-by-step explanation:

This question is a linear equation. First, we will extract the important numbers

amount of snow at beginning=2

snow falling per hour=2.5

trying to find how much snow has fallen after 5 hours.

First, lets put this into an equation, variables will go as follows

total amount of snow=S

hours=H

snow at beginning=B

Rate of snow fall=T

Now, we make an equation

S=T(H)+B

Now, substitute the variables out

S=2.5(5)+2

Then, solve

S=12.5+2

S=14.5

For the second question, just put the equation you made as the answer

The missing coefficients of x² is 8.

According to the question we have been given the expression which is :

        [tex](15x^{2} + 11y^{2} + 8x) - (7x^{2} + 5y^{2} + 2x) = [ ]x^{2} + 6y^{2} + 6x\\[/tex]

In this we have to find the missing coefficient.

To find the missing coefficients we will solve the L.H.S that is

       [tex]= (15x^{2} + 11y^{2} + 8x) - (7x^{2} + 5y^{2} + 2x)[/tex]

First we will eliminate the brackets we get

        [tex]= 15x^{2} + 11y^{2} + 8x - 7x^{2} - 5y^{2} - 2x\\[/tex]

Solving the coefficients of  x² terms , y² terms and x terms we get

        = 8x² + 6y² + 6x

Which is equal to the R.H.S

Combining both the equation we get the coefficient of the x² is 8.

Hence the missing coefficient is 8.

You can measure the 1-positive distance between points A and B by using 3-either point as zero.

Distance means a distance magnitude or a direction vector.

Distance between points A and B is a distance magnitude, which can never be negative because it is the amount of space between the two points.  It does not take into account the direction of the displacement.

The distance between points A and B shows the size of the displacement.  The distance will remain the same whether measured from point A or from point B.

Thus, measuring the points between A and B can start from any of the points, and the measured distance is always positive.

Answer:29

Step-by-step explanation: 174 divided by 6 is 49 becuase 6x49=174

The sum of a number is 92 which is not equal to 4.

8(N+6) = 4

N+6 = 4/8

N=1/2-6

  =11/2

plug that into the original equation to check the solution

8(11/2 + 6) = 4

8(23/2) = 4

8 x23/2 = 4

92 = 4, which is not equal to 4.

An equation is simply a number sentence with a variable in the place of an unknown value. A variable is a letter that is substituted in place of the unknown value. It can be any letter you want, although x or n is most commonly used.There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.

The term “linear”, though derived from the idea that a linear equation in two variables represents a line, has been generalized from that to mean that the equation involves a polynomial with degree 1. That is, the variable(s) are only multiplied by constants and added to other terms, with nothing more (squaring, etc.)

A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line
