Bruce pitches for his little brother's baseball team. He has observed that the number of pitches a batter hits varies and is given by the function f(x) = x – 11, where x is the number of pitches and f(x) is the number of hits. If batters get {4, 12, 14, 27, 42} hits, how many pitches did Bruce throw? A. {13, 21, 24, 26, 44} B. {17, 24, 27, 28, 35} C. {20, 27, 32, 33, 45} D. {15, 23, 25, 38, 53}
Answers
Answer:
D.{15,23,25,38,53}
Step-by-step explanation:
Replace f(x) with any other variables of your choice.
Substitute the value of the variable for the given set of hits
that is {4,12,14,27,42}
Solve for x for each value of the variable from the above set
Put all the solution for x in a set that is inside {,} brackets.

As k₁ = k₂ = k₃, the table represents a linear relation whose constant of variation is - 4.
Does the table represent a linear relation?
A table between two variables represents a linear relation if and only if every pair of values (x, y) have the same constant:
k = y/x (1)
Now we proceed to check the existence of the constant of variation:
k₁ = 8/(- 2) = - 4
k₂ = (- 16)/4 = - 4
k₃ = (- 36)/9 = - 4
As k₁ = k₂ = k₃, the table represents a linear relation whose constant of variation is - 4.

The equation of the line in standard form is 6x - 7y = - 11
How to represent linear equation in standard form?The standard form for linear equations in two variables is Ax + By = C.
Therefore, using (-3, -1)(1 / 2, 2)
y = mx + b
where
m = slopeb = y-interceptHence,
m = 2 + 1 / 1 /2 + 3 = 6 / 7
Hence,
-1 = 6 / 7(-3) + b
- 1 = - 18 / 7 + b
-1 + 18 / 7 = b
b = -7 + 18/ 7
b = 11 / 7
Therefore,
y = 6 / 7 x + 11 / 7
Using the standard form,
6 / 7 x - y = - 11 / 7

The linear equation in standard form is:
6x - 7y = -11
Which is the last option.
How to get the equation of the line?
The line in slope-intercept form is written as:
y = a*x + b
We can see that the line passes through the points (-3, -1) and (1/2, 2), then the slope is:
[tex]a = \frac{2 - (-1)}{1/2 - (-3)} = \frac{3}{3.5} = \frac{6}{7}[/tex]
Then we can write:
y = (6/7)*x + b
To find the value of b, we use the first point. It means that when x = -3, the value of y is -1, then we get:
-1 = (6/7)*-3 + b
-1 + 18/7 = b
-7/7 + 18/7 = b
11/7 = b
Then the equation is:
y = (6/7)*x + 11/7
If we multiply both sides by 7 we get:
7y = 6x + 11
Now we move the term with "x" to the left:
7y - 6x = 11
That is the line in standard form.
If we multiply both sides by -1, we get the last option:
6x - 7y = -11

The equation y = -0.5x +45 represent the linear relationship.
According to the statement
We have given that the When she plants 30 stalks, each plant yields 30 oz of beans and When she plants 33 stalks, each plant produces 29 oz of beans.
And we have to find the linear relationship between the plants which are stalks.
So, For this purpose,
When we consider this graph as a straight line, the two points lying on the line would be
(30, 30) and (34, 28) taking n as horizontal and y vertical
Using two point equation we find that
the equation of the line is
y-y1 / y2-y1 = x-x1 / x2-x1
Substitute the points as x =n and put the other values in it then
y-30 / 28-30 = x-30 / 34-30

Find the difference: -2-6
Answers
I was taught how to solve these kinds of problems easily! Whenever you are subtracting a negative by a positive, you can think of it as using the two minus signs as addition and keeping the result negative. An example of this would be as follows:
Let’s take the problem -7 - 3.
See the two minus signs (the one in -7 and the one that shows we are subtracting)? Well, these two signs can be put together to form an addition sign (+), which shows that we are adding these two numbers together.
7 + 3 = 10
Now that we added the numbers, we can just add the negative sign back on to show that -7 - 3 = -10.
A simple way to remember this is that -7 + 3 would give us -4. This makes things easier to remember because subtraction is the inverse operation of addition, and since adding a negative and positive results in numbers that go more toward the origin and positive numbers side of a number line, we can just do the inverse operation to find that subtracting a negative by a positive number results in numbers moving to the left on a number line, which resembles less and farther from the origin.
Your final answer: -2 - 6 = -8. If you need extra help, let me know and I will gladly assist you.

Which of the following graphs represents a function?
Answers
The third graph represents a function.
In a function, every input (x value) has exactly one output (y value). If even a single input has zero or two outputs, the graph does not represent a function.
A good way of testing this is using a vertical line. As you move a vertical line from left to right across a graph, it should always be touching exactly one point on the graphed line.
In this case, every graph fails this vertical line test except for the third graph, so the third graph represents a function.
