write an equation of the line passing through the point (-20, 4) that is perpendicular to the line 2x+5y=10
Equation of the line passing through the point of (-20, 4) and perpendicular to the line [(2x + 5y) = 10] will be [2y = (5x + 108)].
As per the question statement, a line passes through the point of (-20, 4) and is perpendicular to the line [(2x + 5y) = 10].
We are required to determine the equation of the above-mentioned line.
To solve this question, we need to know about the formula to express the point-slope form of a line, which goes as, [(y - y₁) = m(x - x₁)],
where (x₁, y₁) is a point through which the line passes, and "m" is the slope of the line.
Also, we need to know about the mathematical fact that, the product of the slopes of two perpendicular lines equate to (-1), i.e., if (m₁ and m₂) are the slopes of two perpendicular lines, then [(m₁ * m₂) = (-1)].
Converting [(2x + 5y) = 10] into the point-slope form of line, we get,
(2x + 5y) = 10
or, [5y = {(-2x) + 10}]
or, [y = {(-2/5)x + 2}]
Therefore, Slope of the line [(2x + 5y) = 10] is (-2/5).
Hence, slope of the line perpendicular to [(2x + 5y) = 10] is [-1/(-2/5)], i.e.,
Slope of the line perpendicular to [(2x + 5y) = 10] is (5/2).
Now, using [m = (5/2)] and (x₁, y₁) as (-20, 4), equation of the line will be
[(y - 4) = (5/2){x - (-20)}]
or, [(y - 4) = (5/2)(x + 20)]
or, [(y - 4) = (5/2x) + 50]
or, [2(y - 4) = 5x + 100]
or, [(2y - 8) = (5x + 100)]
or, [2y = (5x + 108)]

An architect makes a model of a new house. The model shows a tile patio in the backyard. In the model, each tile has
1/4
length in. and width 1/6 in. The actual tiles have length 1/6 ft and width 1/9 ft. What is the ratio of the length of a tile in the
model to the length of an actual tile? What is the ratio of the area of a tile in the model to the area of an actual tile? Use
pencil and paper. Describe two ways to find each ratio.
The ratio is 1:8 and 1:64
Since each tile is one sixth of an inch in width and one fourth of an inch in length.
That is L1= 1/4 in addition to W1= 1/6 inches.
The real tiles are one sixth of a foot long and one tenth of a foot wide.
Since 1 foot equals 12 inches, that is in inches and inches. that is L2=2 and W2= 4/3
So, the length of the tile divided by its real length is equal to L1/L2
=(1/4)/2= 1/8
In addition, the relationship between the area of the tile in the model and the real area is given by:
(1/4 x 1/6)/ 2 x 4/3
= 1/64
Second method
Since there is a 1/8 ratio between the width of the model's tiles and their real width

Step-by-step explanation:
You want 88 increased by 14% using the multiplier method.
MultiplierThe multiplier used to increase an amount by some fraction (p) of that amount is (1 +p). Here, the fraction is 14%, or 0.14. That means the multiplier is ...
multiplier = 1 +p
multiplier = 1 +0.14 = 1.14
The increased amount is then ...

Given the point:

Let's find the equation of the line that passes through the point and is perpendicular to the line x = -4.
Here, the given line x = -4 is a vertical line that is always at x = -4.
The slope of a vertical line is undefined.
Since x = -4 is a vertical line it means the slope is undefined.
The slope of a line perpendicular to a vertical line is always zero.
Also, the line perpendicular to a vertical line must be a horizontal line.
Therefore, since the perpendincular line passes the point (-1, 4), it means the line will be:
y = 4

Find the area of the region that is bounded above by the curve f(x)=(x+3)2 and the line g(x)=−x−1 and bounded below by the x-axis.
By definite integrals, we find that the area of the region bounded by the functions f(x) and g(x) described in the statement is equal to 4.5 units.
How to determine the area of the region bounded by two curvesIn this problem we must determine the area between two functions, a quadratic equation f(x) and a linear equation g(x).
First, we need to determine the limits of the interval of x-values with the help of a graphing tool, represented by the points of intersection of the two functions.
The points of intersection of the two functions are (x₁, y₁) = (- 5, 4) and (x₂, y₂) = (- 2, 1), respectively. Then, the area is defined by the following definite integral:
[tex]I = \int\limits^{-2}_{-5} {[g(x) - f(x)]} \, dx[/tex]
[tex]I = \int\limits^{-2}_{- 5} {[(- x - 1) - (x + 3)^{2}]} \, dx[/tex]
[tex]I = - \frac{1}{2} \cdot [(- 2)^{2} - (- 5)^{2}] - [(- 2) - (- 5)] - (1 / 3) \cdot [(- 2 + 3)^{3} - (- 5 + 3)^{3}][/tex]
I = - (1 / 2) · (4 - 25) - 3 - (1 / 3) · (1 + 8)
I = - (1 / 2) · (- 21) - 3 - (1 / 3) · 9
I = 21 / 2 - 3 - 3
I = 21 / 2 - 6
I = 21 / 2 - 12 / 2
I = 9 / 2
I = 4.5
The area of the region represented by the definite integral introduced above is equal to 4.5 units.
RemarkThe statement leads to a contradiction. Correct form is presented below:

What type of linear equation is X +1 equals X +1?
X+1 depicts horizontal linear equation as x = -1 and slope = 0.
Given that the slope is 0, it shows a horizontal linear equation.
Every point on a horizontal line has the same y-coordinate.
If two points have the same y coordinate, b, then the line's equation is y=b.
The y-intercept of the horizontal line y=b is the point (0,b). The line y=0 is the only x-intercept for horizontal lines.
Horizontal lines have zero slope.
As a result, in the slope-intercept equation y = mx + b, m = 0. The equation is Y = b, where b is the y-coordinate of the y-intercept.
A line that is perpendicular to the x-axis is referred to as a horizontal line.
The graph of a relation of the form x = 5 is a line parallel to the origin since the value of x never changes.

The level of ibuprofen in the patients bloodstream increased from 0 hours to 2 hours.
What is ibuprofen?
Ibuprofen is an example of an NSAID that is used to relieve pain, fever, and inflammation. This includes menstruation pain, migraines, and rheumatoid arthritis. Additionally, it can be applied to seal off a premature infant's patent ductus arteriosus. It can be given orally or intravenously. After an hour, it usually begins to function.
In the graph that is attached, the y-axis represents the concentration of ibuprofen in the patient's bloodstream, and the x-axis represents the number of hours since ibuprofen was last consumed.
As we can see from the graph, the curve increases from a time of 0 hours, which corresponds to 0 mg of ibuprofen, to a time of 2 hours, which corresponds to 400 mg of ibuprofen.
The curve starts to descend after that point. We will settle for the first assertion because increase is what we are interested in.

From the given parameters to determine the cost of the airline ticket, we can interpret that that the maximum amount that each ticket costs is $295 while the maximum amount of bags is 5 bags.
How to interpret Equation of a line in slope intercept form?
We are given the linear equation that represents the cost of an airline ticket after adding a number of checked bags as;
y = 145 + 30x
