4(1 - x) + 2 x= -3( x + 1)
Answers
Answer:
x = -7
Step-by-step explanation:
Solve for x:
4 (1 - x) + 2 x = -3 (x + 1)
4 (1 - x) = 4 - 4 x:
2 x + 4 - 4 x = -3 (x + 1)
2 x - 4 x = -2 x:
-2 x + 4 = -3 (x + 1)
Expand out terms of the right hand side:
4 - 2 x = -3 x - 3
Add 3 x to both sides:
3 x - 2 x + 4 = (3 x - 3 x) - 3
3 x - 3 x = 0:
3 x - 2 x + 4 = -3
3 x - 2 x = x:
x + 4 = -3
Subtract 4 from both sides:
x + (4 - 4) = -4 - 3
4 - 4 = 0:
x = -4 - 3

Determine if the sequence is arithmetic. If it is, find the common difference, the 52nd term, and the explicit formula.
34. -11, -7, -3, 1, . . .
Given the explicit formula for an arithmetic sequence find the common difference and the 52nd term.
35. a_n = -30 - 4n
Answers
Answer:
#34. aₙ = 4n - 15; a₅₂ = 193#35. a₅₂ = -238; d = - 4-----------------
Question 34Find the differences in the sequence -11, -7, -3, 1, ...
1 - (-3) = 4,-3 - (-7) = 4,-7 - (-11) = 4The difference is common, so the sequence is an AP.
The nth term is:
\(a_n=a_1+(n-1)d\)\(a_n=-11+(n-1)*4=-11+4n-4=4n-15\)Find the 52nd term:
\(a_{52}=4*52-15=208-15=193\)Question 35Find the 52nd term using the given formula:
\(a_{52}=-30-4*52=-30-208=-238\)Find the previous term:
\(a_{51}=-30-4*51=-30-204=-234\)Find the common difference:
\(d=a_{52}-a_{51}=-238-(-234)=-4\)Answer:
\(\begin{aligned}\textsf{34)} \quad d&=4\\a_n&=4n-15\\a_{52}&=193\end{aligned}\)
\(\begin{aligned}\textsf{35)} \quad d&=-4\\a_{52}&=-238\end{aligned}\)
Step-by-step explanation:
Question 34An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant.
Given sequence:
-11, -7, -3, 1, ...To determine if the given sequence is arithmetic, calculate the differences between consecutive terms.
\(a_4-a_3=1-(-3)=4\)
\(a_3-a_2=-3-(-7)=4\)
\(a_2-a_1=-7-(-11)=4\)
As the differences are constant, the sequence is arithmetic, with common difference, d = 4.
The explicit formula for an arithmetic sequence is:
\(\boxed{a_n=a+(n-1)d}\)
where:
a is the first term of the sequence.n is the position of the termd is the common difference between consecutive terms.To find the explicit formula for the given sequence, substitute a = -11 and d = 4 into the formula:
\(\begin{aligned}a_n&=-11+(n-1)4\\&=-11+4n-4\\&=4n-15\end{aligned}\)
To find the 52nd term, simply substitute n = 52 into the formula:
\(\begin{aligned}a_{52}&=4(52)-15\\&=208-15\\&=193\end{aligned}\)
Therefore, the 52nd term is a₅₂ = 193.
\(\hrulefill\)
Question 35Given explicit formula for an arithmetic sequence:
\(a_n=-30-4n\)
To find the common difference, we need to compare it with the explicit formula for the nth term:
\(\begin{aligned}a_n&=a+(n-1)d\\&=a+dn-d\\&=a-d+dn\end{aligned}\)
The coefficient of the n-term is -4, therefore, the common difference is d = -4.
To find the 52nd term, simply substitute n = 52 into the formula:
\(\begin{aligned}a_{52}&=-30-4(52)\\&=-30-208\\&=-238\end{aligned}\)
Therefore, the 52nd term is a₅₂ = -238.

What is quadratic function ?A quadratic function is a type of polynomial function with a degree of two, represented by a parabolic curve when graphed, and can have a maximum or minimum point known as the vertex.
To determine the correct option, we need to compare each feature given in the options with the graph. Here are the steps:
Step 1: Identify the vertex of the graph.
From the graph, we can see that the vertex is located at (–3,4).
Step 2: Identify the y-intercept.
From the graph, we can see that the y-intercept is located at (0,–5).
Step 3: Identify the x-intercepts.
From the graph, we can see that there are two x-intercepts located at (1,0) and (5,0).
Step 4: Identify the axis of symmetry.
The axis of symmetry is the vertical line that passes through the vertex and divides the parabola into two symmetric halves. From the graph, we can see that the axis of symmetry is the vertical line x = –3.
Comparing the features given in the options with the graph, we can see that option A matches all the features correctly.

Between number of seeds a plant produces and the percent of those seeds that sprout then the correlation coefficient is r = 0.233.
To find the correlation coefficient, we need to use the formula:
r = [n(∑xy) - (∑x)(∑y)] / [√(n∑x² - (∑x)²) × √n∑y² - (∑y)²)]
where n is the number of data points, x and y are the variables, and ∑ represents the sum of the values.
Using the data given, we have:
n = 7, ∑x = 354, ∑y = 414.4, ∑xy = 21636.4
∑x² = 177290, ∑y²= 152162.96
Plugging these values into the formula, we get:
r = [7(21636.4) - (354)(414.4)] / [√(7(177290) - (354)²) × √(7(152162.96) - (414.4)²)]
r = 0.233

To find the value of f(g(-4)), we need to first substitute -4 into the definition of g(x) and then substitute the result into the definition of f(x).
First we substitute -4 into g(x):
g(-4) = 2(-4)^2 + 4(-4) - 8
g(-4) = 2(16) + (-16) - 8
g(-4) = 32 - 16 - 8
g(-4) = 8
Now we substitute 8 into f(x):
f(g(-4)) = f(8) = 2(8) - 4 = 16 - 4 = 12
So the value of f(g(-4)) is 12.
Answer:
28
Step-by-step explanation:
The expression: f(g(-4)) just means calculate the value of g at x = -4 and then calculate what f is equal to at that value g is equal to, so we have to first calculate g(-4) which we can do by substituting in -4 as x.
g(-4) = 2(-4)^2 + 4(-4) - 8
g(-4) = 2(16) - 8 - 8
g(-4) = 32 - 16
g(-4) = 16
Now from here we can substitute 16 as g(-4) in the expression f(g(-4)) which means we want to evaluate g(16) which we can do by substituting in 16 as x.
f(16) = 2(16) - 4
f(16) = 32 - 4
f(16) = 28
So that means f(g(-4)) = 28

Complete this sequence of numbers such that the difference between any two adjacent numbers is the same : 3/k, _, _, 9/2k.
Answers
The completed sequence is: 3/k, 3/k, 3/k, 9/2k.To complete the sequence of numbers with a constant difference between adjacent numbers, we can calculate the common difference by subtracting the first term from the second term.
Let's denote the missing terms as A and B.
The given sequence is: 3/k, A, B, 9/2k.
The common difference can be found by subtracting 3/k from A or B. Therefore:
A - 3/k = B - A = 9/2k - B.
To simplify, we can equate the two expressions for the common difference:
A - 3/k = 9/2k - B.
Next, we can solve for A and B using this equation.
Adding 3/k to both sides gives:
A = 3/k + 9/2k - B.
Now, we can substitute the value of A into the equation:
3/k + 9/2k - B - 3/k = 9/2k - B.
Simplifying further, we have:
9/2k - 3/k = 9/2k - B.
Cancelling out the common terms, we find:
-3/k = -B.
Multiplying both sides by -1, we get:
3/k = B.
