Suppose you planted 3 trees around the north and west sides of one of the houses worth $100,000 on the map. You have increased the property value of the house by $10,000. In addition, the owner will save an average of$50 per year in heating costs.

Assuming that the homeowner lives in the house for another 20 years.

Then the total dollar value of the trees to the homeowner and the community will be

⇒ 10,000 + 50 x 20

⇒ 10,000 + 1,000

⇒ $11,000

1 yard = 3 feet

1 foot = 12 inches

 so 36 inches = 1 yard

765 / 36 = 21.25 yards

the answer would be A because 3 rooms would equal 150 and that would only take 6 hours to complete.

Answer:  The correct option is (A) < .

Step-by-step explanation:  We are given to select the correct mathematical symbol that would best fill in the blank to compare the following two real numbers :

[tex]\sqrt7~~~?~~~\dfrac{14}{5}.[/tex]

First , we need to find the values of both the real numbers in decimal form.

We have

[tex]\sqrt7=2.64575...,\\\\\dfrac{14}{5}=2.8.[/tex]

Since, [tex]2.64575<2.8,[/tex] so we get

[tex]\sqrt7<\dfrac{14}{5}.[/tex]

Thus, the correct mathematical symbol is <.

Option (A) is CORRECT.

Step-by-step explanation:

The equation of the line parallel to [tex]\(5x + 2y = 12\)[/tex] and passing through the point (-2, 4) is given as [tex]\(y = -\frac{5}{2}x - 1\).[/tex]

To find the equation of a line parallel to [tex]\(5x + 2y = 12\)[/tex] and passing through the point (-2, 4), we need to follow these steps:

1. Convert the given equation[tex]\(5x + 2y = 12\)[/tex] into slope-intercept form [tex]\(y = mx + b\).[/tex]

2. Determine the slope of the given line.

3. Use the slope and the given point to find the equation of the parallel line using the point-slope form.

4. Convert the equation into slope-intercept form if needed.

Let's start with step 1:

1. Convert [tex]\(5x + 2y = 12\)[/tex] into slope-intercept form [tex]\(y = mx + b\):[/tex]

  Subtract [tex]\(5x\)[/tex] from both sides:

[tex]\[2y = -5x + 12\][/tex]

  Divide both sides by 2:

[tex]\[y = -\frac{5}{2}x + 6\][/tex]

Now, we know that the slope of the given line is [tex]\(-\frac{5}{2}\)[/tex] . Since the line we're looking for is parallel to this line, it will have the same slope.

2. The slope [tex](\(m\))[/tex] of the parallel line is [tex]\(-\frac{5}{2}\).[/tex]

Next, we use the point-slope form[tex]\(y - y_1 = m(x - x_1)\),[/tex]where [tex]\((x_1, y_1)\)[/tex] is the given point (-2, 4) and [tex]\(m\)[/tex] is the slope.

3. Substitute the values into the point-slope form:

 [tex]\[y - 4 = -\frac{5}{2}(x - (-2))\][/tex]

 [tex]\[y - 4 = -\frac{5}{2}(x + 2)\][/tex]

Now, distribute[tex]\(-\frac{5}{2}\):[/tex]

[tex]\[y - 4 = -\frac{5}{2}x - 5\][/tex]

4. Convert to slope-intercept form:

  Add 4 to both sides:

 [tex]\[y = -\frac{5}{2}x - 5 + 4\][/tex]

[tex]\[y = -\frac{5}{2}x - 1\][/tex]

So, the equation of the line parallel to [tex]\(5x + 2y = 12\)[/tex] and passing through the point (-2, 4) is [tex]\(y = -\frac{5}{2}x - 1\).[/tex]

An equation is formed of two equal expressions. The number of CDs owned by Carlin is 102.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the following points:

Let the variables represent the following numbers as shown,

The number of CDs owned by Chad.

M = 2N ______(1)

The number of CDs owned by Carlin.

= N  ________(2)

The number of CDs owned by Bryce.

O = (6+2N) / 7

And O = 30

30 = (6 + 2N) / 7 ________(3)

From (3), the value of N can be written as,

30 = (6 + 2N) / 7

Multiply both sides by 7

30 x 7 = 6 + 2N

210 = 6 + 2N

Subtract 6 on both sides.

210 - 6 = 6 + 2N - 6

204 = 2N

Divide both sides by 2.

102 = N

N = 102

Thus, the number of CDs owned by Carlin is 102.

Final answer:

A linear equation perpendicular to y=5 is a vertical line, expressed as x=c, where c is any real number. For instance, x=2 is perpendicular to y=5.

Explanation:

A linear equation perpendicular to y=5 would need to have an undefined slope, meaning it's a vertical line. Since y=5 is a horizontal line, a perpendicular line will have no slope value that we can put in terms of y=mx+b, where m represents the slope and b represents the y-intercept. Thus, the equation will be of the form x=c, where c is any real number. This represents a vertical line that crosses the x-axis at the point (c,0).

For example, the linear equation x=2 is perpendicular to y=5 and crosses the x-axis at the point (2,0).

No, (2,5) is not a solution of y = 3x-10

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, an equation y = 3x-10, we need to check whether (2,5) is solution of the give equation or not,

For that put x = 2 in 3x-10 and check whether it equals to 5 or not, if not then (2,5) is not a solution of the equation,

= 3×2-10

= 6-10

= -4

∵ -4 ≠ 5

Hence, No, (2,5) is not a solution of y = 3x-10

Answer:

Given equations have no solution

Step-by-step explanation:

Given -

Three set of equations -

[tex]-3x-4y-3z=-7\\2x-6y+2z=3\\5x-2y+5z=9[/tex]

We will now equate "x" in the first equation in terms of "y" and "Z" and put it in second equation -

[tex]-3x-4y-3z=-7\\x = \frac{1}{3} (-4y -3z+7)\\\frac{2}{3}(-4y -3z+7) -6y+2z=3\\-8.667 y = -1.667\\y = 0.192\\[/tex]

We will substitute the value of y in the under given equation-

[tex]x = \frac{1}{3} (-4y -3z+7)\\x = \frac{1}{3} (-4*0.192 -3z+7)\\x= 2.077-z[/tex]

substituting the derived values in last equation, we get -

[tex]5x-2y+5z=9\\5(2.077-z)-2(0.192)+5z=9\\10.385-5z-0.384+5z=9\\0=-1[/tex]

The solutions of the quadratic equation x² = -5x - 3 are [tex]\( x = \frac{-5 - \sqrt{13}}{2} \)[/tex] and [tex]\( x = \frac{-5 + \sqrt{13}}{2} \)[/tex].

To find the solutions of the quadratic equation x² = -5x - 3, first we rearrange it to the standard form:

x² + 5x + 3 = 0

We solve this using the quadratic formula, which is given by:

x = [tex]\frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

For our equation, a = 1, b = 5, and c = 3. Substituting these values in, we get:

x = [tex]\frac{-5 \pm \sqrt{5^2 - 4*1*3}}{2*1}[/tex]

x =[tex]\frac{-5 \pm \sqrt{25 - 12}}{2}\\[/tex]

x =[tex]\frac{-5 \pm \sqrt{13}}{2}[/tex]

Hence, the solutions are:

x = [tex]\frac{-5 - \sqrt{13}}{2}[/tex] and x = [tex]\frac{-5 + \sqrt{13}}{2}[/tex]

The amount of discount is $1.095 and the discounted sales price is $9.855.

We need to calculate the amount of discount and then subtract it from the original sales price to find the discounted sales price.

First, we calculate the amount of discount. A 10% discount on an item selling for $10.95 means we need to find 10% of $10.95. To find 10% of a number, we can multiply the number by 0.10 (which is the decimal equivalent of 10%).

Amount of discount = 10% of $10.95

= 0.10 [tex]\times[/tex] $10.95

= $1.095

Now that we have the amount of discount, we can calculate the discounted sales price by subtracting the discount from the original sales price.

Discounted sales price = Original sales price - Amount of discount

= $10.95 - $1.095

= $9.855
