What are Variables ?A variable is a symbol and a stand-in for any mathematical object in mathematics. A variable can specifically represent a number, a vector, a matrix, a function, its argument, a set, or one of its elements.
According to the given information
Let x be the variable
Let the number of adults in the fair = x
Number of kids in the fair is 12 more than the adults
So
Number of kids in the fair = 12 + Number of adults in the fair
= 12+x
Hence

Todd has created the following diagram to prove the Pythagorean theorem. He drew right Δ A B C with leg lengths a and b and hypotenuse length c. Then he drew altitude C Z to the hypotenuse. He determines that c/a=a/x and c/b=b/y. Then he determines that c x=a² and c y=b². What is the next step in proving the theorem?
c²=a²+b²
c x=c y
c x+c y=a²+b²
c(x+y)=a²+b²
cx + cy = a² + b² is the next step to prove the theorem.
Given,
The given Pythagorean theorem was created by Todd.
With leg lengths a and b and a hypotenuse length of c, he drew right
ΔABC. The hypotenuse was then drawn with altitude C Z.
He finds that the equations c/a=a/x and c/b=b/y. He then discovers that c x=a² and c y=b².
We have to find the next step to prove the theorem;

What are the vertex and range of y = |4x + 8| − 1? (0, −1); −∞ < y < ∞ (0, −1); −1 ≤ y < ∞ (−2, −1); −∞ < y < ∞ (−2, −1); −1 ≤ y < ∞
The vertex and range of y = |x + 1| + 3 will be (−1, 3); 3 ≤ y < ∞ respectively.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
You may get the vertex of y = |x + 1| + 3 as follows.
Where the absolute values are zeros are the vertex points of the absolute value function.
|x + 1| = 0
x + 1 = 0
x = -1
Substitute the value into an original function,
y = |-1 + 1| + 3
y= 0 + 3
y = 3
As a result, the vertex is at (-1, 3)
Remember that the domain is specified in the range of (-∞, ∞) while determining the range.
Given that |x + 1| ≥ 0 , (absolute value is always 0 or positive)
The result of adding 3 to the inequality's two sides is
|x + 1| + 3 ≥ 3
But since |x+1| + 3 is identical to f(x) = y, we have y = f(x) 3, which means that the range is specified for all values larger than 3.
So the range is 3 ≤ y < ∞
Thus,the vertex and range of y = |x + 1| + 3 will be (−1, 3); 3 ≤ y < ∞ respectively.

During bowling practice, Marley rolled 28 strikes out of 70 attempts. What percent of Marley's
attempts were strikes?
40 percent of Marley's attempts were strikes, when Marley rolled 28 strikes out of 70 attempts.
Define percentage.Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. You divide the part of the whole by the whole and multiply the result by 100 to get the percentage. A % is a number that indicates how many out of 100 it is, and it can also be expressed as a decimal or a fraction. Put the percentage value in the numerator and 100 in the denominator to convert a percentage to a fraction.
Given,
28 strikes rolled by Marley
Total attempts = 70
For percentage,
28/ 70 × 100%

Wile Coyote is chasing after the famous Road Runner one afternoon. The roadrunner sets off at a
speed of 72mph, while the coyote has issues with his rocket bike. It takes him 15 minutes to
repair it, then he shoots after him. The coyote is not worried at all because his ACME rocket bike
has a speed of 220mph. How long (in minutes) has the Road Runner been running once the
coyote catches up to him?
The time the Road Runner been running is 7.3 minutes
How to determine the time the Road Runner been running?From the question, we have the following parameters that can be used in our computation:
Roadrunner speed = 72mph
Time for repair = 15 minutes
Speed = 220mph
Represent the time the Road Runner been running with x
The speed is calculated using
Speed = Distance/Time
So, we have the following representations
Roadrunner speed = Distance/Time
Wile Coyote speed = Distance/Time
This gives
72 = Distance/(15 + x) -- for the roadrunner
220 = Distance/x for the Wile Coyote
So, we have
Distance = 72(15 + x)
Distance = 220x
Substitute the known values in the above equation, so, we have the following representation
220x = 72(15 + x)
Open the brackets
220x = 1080 + 72x
Evaluate the like terms
148x = 1080
So, we have
x = 7.3
Hence, the minutes is 7.3 minutes

B. 0.08x + 20
C. 0.1x + 10
D. 0.12x
Answer:
b. 0.08x + 20
Step-by-step explanation:
its B because the price goes up $40 every 500 KW's so
40 divided by 500 = 0.08
The expression used to calculate Naomi's electricity cost after using x kilowatt hours is 0.08x+20. Therefore, option B is the correct answer.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
From the graph we have, (500, 60), (1000, 100), (1500, 140) and (2000, 180).
We know that, slope of a line is Slope=(y2-y1)/(x2-x1)
= (100-60)/500
= 40/500
= 0.08
Substitute m=0.08 and (x, y)=(500, 60) in y=mx+c, we get
60=0.08(500)+c
60=40+c
c=20
Substitute m=0.08 and c=20 in y=mx+c, we get
y=0.08x+20
The expression used to calculate Naomi's electricity cost after using x kilowatt hours is 0.08x+20. Therefore, option B is the correct answer.

What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)

Find the equation of the tangent line that crosses the function, f(x) = x^2-5, at x=-2
Answer:
We can use the point-slope formula to find the equation of the tangent line. The point-slope formula is given by:
y - y1 = m(x - x1)
where (x1, y1) is a point on the line, and m is the slope of the line. To find the equation of the tangent line, we need to find the slope of the line and a point on the line.
To find the slope of the line, we can use the definition of derivative. The derivative of a function f(x) at a point x0 is defined as:
f'(x0) = lim(h->0) (f(x0 + h) - f(x0))/h
In our case, the function f(x) is given by f(x) = x^2 - 5, and the point x0 is -2, so we have:
f'(-2) = lim(h->0) (f(-2 + h) - f(-2))/h
Substituting the value of the function f(x) = x^2 - 5, we get:
f'(-2) = lim(h->0) (((-2 + h)^2 - 5) - ((-2)^2 - 5))/h
Simplifying the expression, we get:
f'(-2) = lim(h->0) (h^2 - 4h)/h
Since the limit is defined as h approaches 0, we can drop the h from the denominator since it will become insignificant in the limit:
f'(-2) = lim(h->0) (h^2 - 4h)
Now we can evaluate the limit as h approaches 0:
f'(-2) = lim(h->0) h^2 - 4h
In the limit, h^2 becomes 0, so we are left with:
f'(-2) = lim(h->0) - 4h
Since the limit is defined as h approaches 0, the value of the limit is simply -4 times 0, which is 0. Therefore, the slope of the tangent line is 0.
Now that we know the slope of the tangent line, we need to find a point on the line. We are told that the line passes through the point (-2, f(-2)) on the function f(x) = x^2 - 5. Substituting the value of the function, we get:
(-2, f(-2)) = (-2, (-2)^2 - 5) = (-2, -9)
So the point on the line is (-2, -9).
We now have the slope and a point on the line, so we can use the point-slope formula to find the equation of the line. Substituting the values into the point-slope formula, we get:
y - (-9) = 0(x - (-2))
Simplifying, we get:
y = -9
Therefore, the equation of the tangent line that passes through the point (-2, -9) with a slope of 0 is given by y = -9.
