Answer:
Step-by-step explanation:
To find the equation of a line passing through two points, we can use the slope-point form:
y - y1 = m(x - x1)
where (x1, y1) is one of the points on the line, m is the slope of the line and can be calculated as
m = (y2 - y1) / (x2 - x1)
where (x2, y2) is the second point on the line.
Given the points (-6, -5) and (4, -3), we can substitute the values into the slope formula to find m:
m = (-3 - (-5)) / (4 - (-6)) = 2 / 10 = 1/5
Next, we can substitute the point (-6, -5) and the slope 1/5 into the slope-point form to find the equation of the line:
y - (-5) = 1/5 (x - (-6))
y + 5 = 1/5 x + 6
5y + 25 = x + 30
5y = x + 5
y = (x + 5) / 5
Thus, the equation of the line passing through the points (-6, -5) and (4, -3) is y = (x + 5) / 5.

You must first formulate a polynomial equation in standard form before you can solve it. Factor it, then set the values of each variable factor to zero after it reaches zero.
How do you calculate a polynomial?The original equations' answers are the answers to the derived equations. Factoring cannot be used to resolve all polynomial equations.
The sum of terms with the pattern kxn, where k is any number and n is a positive integer, is what we call a polynomial.
It is impossible to classify an expression as a polynomial if it contains a variable with exponents that are negative or fractional, divides by a variable, or is included inside a radical.

M
3,600 s. 1,760 yd.
N
3,600 s. • 1,760 yd.
9 s. • 100 yd.
Answer: To find Usain's speed in miles per hour, we need to convert the distance from yards to miles and the time from seconds to hours. To convert yards to miles, we divide the number of yards by the number of yards in a mile (1,760). To convert seconds to hours, we divide the number of seconds by the number of seconds in an hour (3,600).
So, to find Usain's speed, we use the formula:
Speed = Distance / Time
In this case, we have:
Speed = (100 yd) / (9 s)
We need to convert yards to miles and seconds to hours, so we can use the following conversion factors:
1 yd = 1/1,760 mi
1 s = 1/3,600 hr
By applying this conversion factor we get the speed in miles/hour.
Speed = (100 yd) / (9 s) * (1/1,760 mi/yd) * (1/3,600 hr/s)
So the final answer will be:
Speed = (100/9) * (1/1,760) * (1/3,600) miles/hour
Hence, option M: 3,600 s is the final answer.

How are scale drawings formed?For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means

Graph the solution of |2x-1|=3 on the number line.
The graph of the solutions of the absolute value equation can be seen on the image at the end.
How to graph the solution of the equation?Here we have the absolute value equation:
|2x - 1| = 3
We can "break" that absolute value equation into two simpler ones, we will get:
(2x - 1) = 3
(2x - 1) = -3
Now we can solve these two, we will get for the first one.
2x - 1 = 3
2x = 3 + 1
x = 4/2
x = 2
The other gives.
2x - 1 = -3
2x = -3 + 1
2x = -2
x = -2/2 = -1
The solutions are 2 and -1, then the graph is the one below.

An Uber ride costs $13.15 for a 3 mile trip and $18.25 for a 5 mile trip find the rate of the cost per mile
The cost per mile for both trips are $4.5 and $3.65
How to calculate the cost per mile ?An uber ride costs $13.15 for a 3 mile trip and $18.25 for a 5 mile trip
The cost per mile for both trips can be calculated as follows
The first step is to calculate the cost of mile for the First trip
13.15= 3
x= 1
cross multiply both sides
3x= 13.15
x= 13.15/3
x= 4.5
The next step is to calculate the cost of mile for the Second trip
18.25= 5
y= 1
cross multiply both sides
5y= 18.25
y= 18.25/5
y= 3.65
Hence the cost per mile for both trips are $4.5 and $3.65

want a garden at their respective homes, and they decide they want to
build identical flower gardens that are in the shape of a triangle.
They spend a lot of time emailing and talking on the phone, trying to
figure out how to make these triangular gardens exactly the same.
• Sue suggests that they each make their gardens with brick walls
outlining the gardens, and they should make sure all three angles
of the two triangles are the same: 30, 60, and 90. Sue asserts
that this will make their gardens congruent.
Pam likes the idea of the wall, but instead she thinks that they
should make their triangles equal by making one wall 7 feet long
with a 30 angle attached to it. Sue says the other two walls
will match up to make a triangle, and that their triangles will
be equal.
The two women can't agree on the best method. They hire you to help
them with the design.
Determine if either of their methods will create congruent
triangular gardens. Use your congruent triangle theorems, like

What is the speed of an object?Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time
Given here: The distance is 93,000,000 miles and the speed of light as 1.86×10⁵ miles per hour.
Now we know speed = Distance/ time
