How many feet of the parking lot are presented by 1 centimeter on the scale drawing?

answer :

so this is the answer of the value of x

The solution of the linear equation is x = 21.

Here we have the linear equation:

5x - 2x + 5 = 2x + 26

To solve this for x, move all the terms with x to the left side and all the others to the right side:

5x - 2x - 2x = 26 - 5

5x - 4x = 21

x = 21

The solution of the linear equation is x = 21.

Answer:

[tex]\sqrt{13}[/tex]

Step-by-step explanation:

First calculate the 3-5 Triangle

Using Pythagorean Theorum,

[tex]\sqrt{5^{2}-3^{2} } =4[/tex]

That means that the other triangle side is 2.

Using Pythagorean Theorum again,

[tex]\sqrt{3^{2}+2^{2} } =\sqrt{13}[/tex]

The lines represented by y = -5x + 10 and 5y = x + 15 are; Perpendicular

We are given the equation of two lines as;

Line 1; y = -5x + 10

Line 2; 5y = x + 15

Now, the equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Now, for the equation in line 1, we know that;

slope = -5 while the y-intercept is 10

For line 2, the equation can be rewritten as;

y = ¹/₅x + 3

Slope = 1/5

y-intercept = 3

Now, we know that when two lines are perpendicular, it means that their slopes are negative reciprocals of each other.

Slopes of lines 1 and 2 are negative reciprocals of each other and thus they are perpendicular.

Step-by-step explanation:

Given equation

Expand the parenthesis

[tex]-5x+6+4x=-2\times3x-2\times(-4)[/tex]

[tex]-5x+6+4x=-6x+8[/tex]

Combine like terms

The linear equation in the slope-intercept form is:

y = (-1/3)*x + 4

Remember that if a line passes through two points (a, b) and (c, d), then the slope is given by:

slope = (d - b)/(c - a)

By looking at the graph, we can see that the points (0,4) and (3, 3), then the slope will be:

s = (3 - 4)/(3 - 0) = -1/3

And we can see that the y-intercept is y = 4 (because the line passes through the point (0,4))

Then the linear equation in the slope-intercept form is:

y = (-1/3)*x + 4

The value of the angle SRT using the given parameters is; ∡SRT = 90°

Collinear points are the points that lie on the same straight line or in a single line. Thus, the points T and W are collinear.

We are told that ∡TRV ≅ ∡VRW. That congruency statement can only be possible if both angles are 90°.

From the above, it means that we can say that;

∡TRV = ∡VRW = 90°

The rule is reflection in y=x (x, y)→(y, x) and reflection in y=-x (x, y)→(-y, -x).

Given that, a rotation and reflection composition is equivalent to other compositions.

Reflection is flipping an object across a line without changing its size or shape. Rotation is rotating an object about a fixed point without changing its size or shape.

Rotation rule:

Rotation of a point through 180°, about the origin when a point A (x, y) is rotated about the origin O through 180° in the anticlockwise or clockwise direction, it takes a new position A' (-x, -y).

Reflection rule:

A vertical reflection reflects a graph vertically across the x-axis, while a horizontal reflection reflects a graph horizontally across the y-axis.

Therefore, the rule is reflection in y=x (x, y)→(y, x) and reflection in y=-x (x, y)→(-y, -x).

The decay factor for the annual rate of change of - 55 % is 0.45.

A quantity must vary by a specific percentage each time period in order for growth or decay to be exponential.

With the function displayed to the right, you may represent exponential growth or decay.

A(x) = a( 1 + r)ˣ

Where A is the amount after x time periods, a is the initial amount, x is the number of time periods, and r is the rate of change.

Now, we have the annual rate of change as:

r = - 55 % = - 55 / 100 = - 0.55

From the function A(x) = a( 1 + r)ˣ , the corresponding factor is 1 + r.

So, let B = 1 + r

B = 1 + r

B = 1 + (- 0.55)

B = 1 - 0.55

B = 0.45

The Binomial theorem tells us how to expand expressions of the form (a + b)ⁿ, for example, (x + y)⁷. The larger the power is, the harder it is to expand expressions like this directly.

The total number of terms in the expansion of (x+y)ⁿ are (n+1).

The sum of exponents of x and y is always n.

The given logarithmic representation i.e., (log x)² = log x² is true only for x = 1 and 100 and for rest it is not valid.

Given that, (log x)² = log x², let's proceed to simplify this in order to reach at the conclusion part.

(log x)² = log x²

(log x)² = 2log x

(log x)² - 2log x = 0

log x(log x - 2) = 0

⇒log x = 0 or log x - 2 = 0

Now, put log x = 0

⇒ x = 1

Now, put log x - 2 = 0

log x = 2

log x = 10²

x = 100

Hence, we got two values for x one is 1 and other is 100. Now, putting one by one in (log x)² = log x² in order to reach at the conclusion.

Put x = 1 in (log x)² = log x², we get

(log 1)² = log 1²

0 = 0²

0 = 0

⇒ true for x = 1

Now, put x = 100 in (log x)² = log x² , we get

(log 100)² = log 100²

2² = 2log 100

4 = 2 x 2

4 = 4

⇒ true for x = 100

So, (log x)² = log x² is true only when x = 1 and 100 for rest it is false.
