Write an equation for (-5,3) and (0,-7)
The equation of line is y + 2x +7 =0 for the points (-5,3) and (0,-7).
What is equation of line?A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.
The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.
The given points are (-5, 3) and (0, -7).
To find the equation of line, use formula,
y - y₁ = m(x - x₁) where m = (y₂-y₁)/(x₂-x₁),
y - 3 = (-7 - 3)/(0-(-5)) (x - (-5))
y - 3 = -10 / 5 (x + 5)
y - 3 = -2 (x + 5)
y + 2x +7 =0
The required equation of line is y + 2x +7 =0 .

Given f(x) = 2x and g(x) = f(x − 4) + 5, write the new function rule (equation) for function and
describe
The new function rule is g(x) = 2x -3
What is a function?A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
This means that if the object x is in the set of inputs (called the domain) then a function f will map the object x to exactly one object f(x) in the set of possible outputs (called the codomain).
if f(x) = 2x, then f(x-4) = 2(x-4)
g(x) = f(x-4) + 5
substitute f(x-4) into g(x)
g(x) = 2(x-4) + 5
g(x) = 2x -8 + 5
g(x) = 2x - 3
In conclusion, the function rule g(x) is 2x - 3

In Silvergrove, the library is due south of the courthouse and due west of the community swimming pool. If the distance between the library and the courthouse is 9 kilometers and the distance between the courthouse and the city pool is 10 kilometers, how far is the library from the community pool? If necessary, round to the nearest tenth.
The distance of the library from the community pool is given as 4.4 km
How to solve for the distanceWe have to solve this problem with the use of the Pythagoras theorem.
The formula is given as
a² = b² + c²
The total distance flown would be represented by a = 10 kilometer
the distance for the courthouse would be given as 9 kilometers
When we put these values in the formula we would have
10² = a² + 9²
100 = a² + 81
a² = 100 - 81
a² = 19
a = √19
a = 4.4 km
Hence the calculated distance is given a 4.4 km from the library to pool.

Scott whose eye level is 1.5m above the ground, stands 30m from a tree. The angle of elevation of a bird at the top of the tree is 36 degrees. How far above the ground is the bird?
A. 21.8 m
B. 23.3 m
C. 41.3 m
Using trigonometric ratio, the distance of the bird is 21.8m
Angle of ElevationThe angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.
To solve this problem, we have to use trigonometric ratio of SOHCAHTOA
Let's define the variables given;
Using Tangent of an angle;
tanθ = opposite / adjacent
tan 36 = x / 30
Cross multiply both sides and solve for x
30 tan36 = x
21.8 = x

Consider the curve given by the equation y² - 6y - 9x² - 144x = 576. It can be shown that dy/dx=
9(x + 8)/ Y-3
Find the x-coordinate of the point where the line tangent to the curve is the x-axis.
The x-coordinate of the point where the line tangent to the curve is the x-axis is; x = -8
How to Interpret the tangent line to a curve?To get he x-coordinate of the point that the line tangent to the curve is the x-axis, what we will do is to equate the numerator of the derivative to zero.
Now, we are given the equation of the curve as;
y² - 6y - 9x² - 144x = 576.
We are told that It can be shown that;
dy/dx = 9(x + 8)/(y - 3)
From our earlier definition, the x-coordinate will be at;
9(x + 8) = 0
divide both sides by 9 to get;
x + 8 = 0

100 ⇒ 20 ⇒ 120
30 ⇒ 20 ⇒ x
Accordingly,
100 ⇒ 120

The equation of asked line is y = x/3+3
What is equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
The equation of a line passing through two points (x1, y1) and (x2, y2) is
y-y1 = (y2-y1)/(x2-x1)*(x-x1)
The two points are (6, 5) and (3, 1)
Equation =
y-5 = -4/-3*(x-6)
y-5 = 4/3*(x-6)
3y - 15 = x-6
3y = x+9
y = x/3+3

What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
Chindi puts 2(3/5) kg of bird seed in his large feed.
This is 1(3/10) times as much bird seed as he puts in his smaller feeder.
The total amount is represented by 1.
Now,
1(3/10) = 2(3/5) kg
13/10 = 13/5 kg
Multiply both sides by 10/13
1 = 10/13 x 13/5 kg
1 = 2 kg
This means the total amount of seeds in the smaller feeder is 2 kg.
Thus,
The total amount in the smaller feeder is 2 kg.
