solve for y. y/6 = 3/9 simplify your answer as much as possible
Answer: y=2
Step-by-step explanation:
y/6 = 3/9 multiply both sides by 6/1 (since 6/1 times y/6 equals 1y or just y)
y = 18/9 now that y is isolated, just simplify 18/9
y=2 18 divided by 9 is 2

Answer:
A
X, 5x
Step-by-step explanation:
A
X, 5x yes, both variables are x
B
3x, 2xy no, the first variable is x the second is x times y
C
2x, 2y no the first variable is x and the second is y
D
-4, -4y no, the first is a constant and the second has a variable
Answer:
Pair A
Step-by-step explanation:
Pair A (x, 5x) are like terms.
Like terms are terms in a expression or equations with the same variables.
'x' and '5x' have the same variable (you can think of 'x' as '1x'), so they are like terms. All other pairs have different variables.

Suppose f has absolute minimum value m and absolute maximum value M. Between what two values must 7 f(x) dx 4 lie?Which property of integrals allows you to make your conclusion?
Answer:
3m ≤ ∫ f(x) dx ≤ 3M, at limit of b, a
Step-by-step explanation:
Like the question asked, which property of integral was used.
Property 8 of integrals was the basis upon which the question was solved.
The property of the integral is used to solve the problem. The function is given below.
[tex]3m & \leq \int_a^b f(x)dx \leq 3M \end{aligned}[/tex]
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
Suppose f has absolute minimum value m and absolute maximum value M.
We know that the property of the integral can be used.
If m ≤ f(x) ≤ M ∀ a ≤ x ≤ b. Then we have
[tex]m (b-a) \leq \int_a^b f(x) dx \leq M(b-a)\\[/tex]
Then we have
[tex]m \leq f(x) \leq M \ \ and \ \ 4 \leq x \leq 7[/tex]
This means that
[tex]\begin{aligned} m(7-4) & \leq \int_a^b f(x)dx \leq M(7-4)\\\\3m & \leq \int_a^b f(x)dx \leq 3M \end{aligned}[/tex]

A football is thrown by a quarterback to a receiver. The points in the figure show the height of the football, in feet, above the ground in terms of its distance, in yards, from the quarterback. Use this information to solve the problem. Find the coordinates of point B.
Answer:
Coordinates of the point B will be (14, 3.5).
Step-by-step explanation:
From the graph attached,
Distance between the Quarterback and Receiver = x-coordinate of the point B = 14 yards
Similarly, height of the football from the ground at point B = y-coordinate of the point B = 9 + [tex]\frac{12-9}{2}[/tex]
= 9 + 1.5
= 10.5 feet
Since, 1 feet = [tex]\frac{1}{3}[/tex] yards
10.5 feet = [tex]\frac{10.5}{3}[/tex]
= 3.5 yards
Therefore, coordinates of the point B will be (14, 3.5).

17. Write a quadratic equation to find two consecutive odd natural numbers whose
product is 63. Then find the numbers
Answer:
7 and 9
Step-by-step explanation:
So we want two consecutive odd numbers whose product is 63.
Let's write an equation.
Let's let n be a random integer: doesn't matter what it is. Therefore, the first integer must be 2n+1.
This is because we're letting n be whatever it wants to be. If we multiply that whatever number by 2, then it will turn even. If we add 1 to an even number, it becomes odd.
Therefore, our first odd number is (2n+1). Our second, then, must be (2n+3).
Multiply them together. They equal 63. Thus:
[tex](2n+1)(2n+3)=63[/tex]
Expand:
[tex]4n^2+6n+2n+3=63[/tex]
Combine like terms:
[tex]4n^2+8n+3=63[/tex]
Subtract 63 from both sides:
[tex]4n^2+8n-60=0[/tex]
Divide both sides by 4:
[tex]n^2+2n-15=0[/tex]
And now, factor:
[tex](n+5)(n-3)=0[/tex]
Zero Product Property:
[tex]n+5=0\text{ or } x-3=0[/tex]
Find n:
[tex]n=-5\text{ or } n=3[/tex]
So, we've found n.
Then the first integer is either:
[tex]2(-5)+1 \text{ or } 2(3)+1[/tex]
Evaluate:
[tex]-9 \text{ or } 7[/tex]
However, we want two consecutive odd natural numbers. So, ignore the -9.
Therefore, our first odd integer is 7.
And our second one would be 9.
So, our answer is 7 and 9.
And we're done!
Which of the following would you consider to be an example of a geometric line segment? Please
explain your answer or answers.
The 10-yard line on a football field
A scientist's line of vision as he looks into space with a telescope
A line of 15 dancers on stage
A light shone into the darkness
Hands of a clock
Answer:
The 10-yard line on a football field
Step-by-step explanation:
A geometric line segment is a straight path of points(that is a line) that has two end points (that is a beginning and an end). A 10 yard line on a football field is a line segment because it has two endpoints which is at the beginning of the 10 yard and at the end of the 10 yard.
A scientist's line of vision as he looks into space with a telescope is not a line segment because it extends forever (has no end).
A line of 15 dancers on stage is not a line segment, A light shone into the darkness is not a line segment because it continues forever and also, the hands of a clock is also not a line segment.

What is regression analysis?Regression analysis is a group of statistical procedures used in statistical modeling to determine the relationships between a dependent variable and one or more independent variables.
A scatter plot is a particular kind of plot or mathematical diagram that displays values for typically two variables for a collection of data. It uses Cartesian coordinates. When the points are coded, a further variable can be seen.
Given that store recorded the number of sweatshirts sold on several days throughout the year. The scatterplot shows the relationship between the average daily temperature and the number of sweatshirts sold.
Here is the scatter plot, it is observed that by increasing the temperature the number of sweatshirts sold is decreasing. For every 10-degree depression of temperature, the number of the sells is decreased by 50.
Therefore, for every 10-degree increase in temperature, the store sells around 50 fewer sweatshirts. The correct option is D.

Find and simplify the following for f(x)=x(22-x), assuming h ≠ 0 in (C),a. f(x + h)b. f(x+h)- f(x)c. f(x+ h)- f(x)/h
Answer:
The answer is below
Step-by-step explanation:
Given that f(x)=x(22-x)
a) f(x)=x(22-x)
f(x + h) = (x + h)(22 - (x + h))
f(x + h) = (x + h)(22 - x - h)
f(x + h) = (22x - x² - xh + 22h - xh - h²)
f(x + h) = (-x² + 22x - h²+ 22h - 2xh)
b) f(x)=x(22-x) = 22x - x²
f(x + h) = (-x² + 22x - h²+ 22h - 2xh)
f(x+h)- f(x) = (-x² + 22x - h²+ 22h - 2xh) - (22x - x²)
f(x+h)- f(x) = -x² + 22x - h²+ 22h - 2xh - 22x + x²
f(x+h)- f(x) = -x² + x² + 22x - 22x - h²+ 22h - 2xh
f(x+h)- f(x) = - h²+ 22h - 2xh
c) f(x+h)- f(x) = - h²+ 22h - 2xh
[tex]\frac{f(x+h)-f(x)}{h}=\frac{- h^2+ 22h - 2xh}{h}\\ \\\frac{f(x+h)-f(x)}{h}=\frac{- h^2}{h}+\frac{22h}{h}-\frac{2xh}{h}\\\\\frac{f(x+h)-f(x)}{h}=-h+22-2x[/tex]
[tex]\lim_{h \to 0} \frac{f(x+h)-f(x)}{h}= \lim_{h \to 0} (-h+22-2x )=22-2x[/tex]

In a hockey game, Seth took 12 shots and scored 3 times.
Zak took 10 shots and scored twice. Who scored on a
greater fraction of his shots?
Answer:
Seth
Step-by-step explanation:
Seth:3/12 = 0.25
0.25*100 = 25%
Seth scored at 25%
Zak:2/10 = 0.2
0.2*100 = 0.2
0.2*100 = 20%
Zak scored at 20%
then:
25>20
then:
Seth scored on a greater fraction of his shots.
Zak scored on a greater fraction of his shots.
Given,
In a hockey game, Seth took 12 shots and scored 3 times.
Zak took 10 shots and scored twice.
We need to find who scored on a greater fraction of his shots.
How do we compare fractions?
We can compare fractions by finding their decimal values a nd comparing them.
Example: 1/2 and 2/5
1/2 = 0.5
2/5 = 0.4
0.5 is greater than 0.4.
Find the number of score Seth shots out of 12 shots.
= 3
We can write in fractions as:
3/12 _____(1)
Find the number of score Zak shots out of 10 shots.
= 2 x 3
= 6
We can write in fractions as:
6/10 _____(2)
Compare (1) and (2)
3/12 = 1/4 = 0.25
6/10 = 3/5 = 0.6
0.25 is less than 0.6
6/10 is a greater fraction than 3/12
