What must be a factor of the polynomial function f(x) graphed on the coordinate plane below?
A. X-2
B. X-1
C. X+1
D. X+2
Answers
Answer:
Step-by-step explanation:
Answer C (x + 1) is correct; if we let x + 1 equal 0, we get the root (x-intercept) -1, which appears on this graph
X + 1 must be a factor of the polynomial graphed
How to find the factor
The factor is solved using the points where the graph intersects the x-axis.
This points are called the roots
Examining the graph the roots are x = -1 and x = 4
Hence x + 1 must be a factor

Six times a number increased by 26 is 296
What is the number?
Answers
Answer:
x = 45
Step-by-step explanation:
6x+26 = 296
6x+26-26 = 296-26
6x = 270
x = 45
Answer:
45
Step-by-step explanation:
Write the equation:
6n+26= 296
Subtract 26 from both sides:
6n+26-26= 296-26
Simplify:
6n= 270
Divide 6 by each side to get n by itself:
6n/6= 270/6
Simplify:
n= 45
15x – 7 = 4x – 18
What is x
Answers
Answer:
x = - 1
Step-by-step explanation:
Given
15x - 7 = 4x - 18 ( subtract 4x from both sides )
11x - 7 = - 18 ( add 7 to both sides )
11x = - 11 ( divide both sides by 11 )
x = - 1

Different members are found in each sample,some members may possibly overlap in each sample,both samples would be representative of the population
Explanation:
Lana and Jeff selected the sample randomly. A Random sample is one where equal chances are given to everyone. It is selected in an unbiased manner.
There can be many possibilities in the selection of a sample of 15 students to study their favorite movies. Like:
Different members are found in each sample- the Lana and Jeff might select a sample from their own sources. So it might include different members.Some members may overlap- if Lana And Jeff are related then some of their members might be the same.Both samples would be the representative of the population- Sample would tell us about the entire population.

What is the value of x in the system of equations shown below?
5x + 4y= 1
Y= 1 -x
Answers
Answer:
The solution to this system of equations is x = -3 and y = 4.
Step-by-step explanation:
In order to solve this system we will use the second equation, which have the "y" isolated on the left side and use that value for "y" in the first equation. This is shown bellow:
5x + 4(1 - x) = 1
5x + 4 - 4x = 1
5x - 4x = 1 - 4
x = -3
Now we can use the value we found for x in the second equation to determine y.
y = 1 - x
y = 1 - (-3) = 1 + 3
y = 4
So the solution to this system of equations is x = -3 and y = 4.

You roll two number cubes. What is the probability of rolling double threes?
Answers
The probability of rolling double threes with two number cubes is calculated by multiplying the likelihood of each die showing a three independently, which is 1/6. Since each die is independent, the combined probability is 1/6 x 1/6 or 1/36.
When rolling two number cubes, often referred to as dice, the probability of rolling double threes is determined by considering the likelihood of each event occurring independently. Each die has six faces, so the probability of rolling a three-on-one die is 1/6. Since the outcome of rolling the second die is independent of the outcome of the first die, its probability of showing three is also 1/6.
The combined probability of both independent events occurring—that is, rolling a three on both dice—is found by multiplying the probabilities of the individual events. This means the probability is 1/6 multiplied by 1/6, which equals 1/36. So, the chance of rolling double threes is 1/36.
If we were discussing a different combination, such as rolling a one and a three, we would add the probability of the first die rolling a one and the second a three to the probability of the first die rolling a three and the second a one. But in the case of double threes, there is only one possible outcome that meets the criteria (a three on the first die and a three on the second) and therefore only one product of probabilities to consider.

(1,1)
Answers
Answer:
(2,3)
Step-by-step explanation:
Substitute y = 2x - 1 in the equation y = 5x - 7
2x - 1 = 5x - 7
2x - 1 + 7 = 5x
2x + 6 = 5x
6 = 5x - 2x
6 = 3x
3x = 6
x = 6/3
x = 2
Substitute the value of x in, y = 2x - 1
y = 2*2 - 1
y= 4 - 1
y = 3

4x+1=3
Can you give me a value for x that makes this equation false?
Answers
For this equation, x = 1/2 makes it true.
4x + 1 = 3
To find a value for x that makes this equation true, we need to find a value where 4x + 1 equals 3.
4x + 1 = 3
Subtracting 1 from both sides:
4x = 2
Dividing both sides by 4:
x = 2/4
Simplifying:
x = 1/2
Substituting x = 1/2 into the equation:
4 . 1/2 + 1 = 3
2 + 1 = 3
3 = 3
Question
Mosi is putting together his monthly budget and would like to know how much he makes in a month. His annual net salary is
$52,000. What is his monthly pay rate, rounded to the nearest dollar?
Answers
Final answer:
Mosi's monthly pay rate, calculated from his annual net salary of $52,000 and divided by 12 months, is $4,333 when rounded to the nearest dollar.
Explanation:
To calculate Mosi's monthly pay rate from his annual net salary, we need to divide his total annual net income by the number of months in a year. Since Mosi's annual net salary is $52,000, we perform the following calculation:
Monthly Pay Rate = Annual Net Salary ÷ Number of months in a year
Monthly Pay Rate = $52,000 ÷ 12
The result is a monthly pay rate of $4,333.33. However, the question asks us to round to the nearest dollar. Therefore, Mosi's monthly pay rate is $4,333 when rounded to the nearest dollar.

Using Euler's Formula, given Edges = 12, Vertices = 8, how many Faces?
A.10
B.8
C.6
D.4
Answers
Answer:
C
Step-by-step explanation:
Euler's formula for polyhedra states that
F + V - E = 2 ( F is faces, V vertices and E edges ), thus
F + 8 - 12 = 2, that is
F - 4 = 2 ( add 4 to both sides )
F = 6
The number of faces is 6
Circle $O$ is located on the coordinate plane with center at $(2,3)$. One endpoint of a diameter is at $(-1,-1)$. What are the coordinates of the other endpoint of this diameter? Express your answer as an ordered pair.
Answers
To find the other endpoint of the diameter of a circle, you can use the midpoint formula in reverse with the given center and one endpoint. In this case, the coordinates of the other endpoint of the diameter are (5, 7).
The coordinates of the other endpoint of a diameter of a circle given that one endpoint and the center of the circle are known. We know the center of the circle, O, is at (2, 3) and one endpoint of the diameter is at (-1, -1). The diameter of a circle is a straight line through the center connecting two points on the circle. If you have one endpoint (x₁, y₁) and the center (x₂, y₂), the coordinates of the other endpoint (x₃, y₃) can be calculated using the midpoint formula in reverse:
x₃ = 2 × x₂ - x₁
y₃ = 2 × y₂ - y₁
For this circle:
x₃ = 2 × 2 - (-1) = 4 + 1 = 5
y₃ = 2 × 3 - (-1) = 6 + 1 = 7
So, the coordinates of the other endpoint of the diameter are (5, 7).

L=U²A divided by (A+B)² make A the subject of formular
Answers
Answer:
A = [- 2Bl + U^2 +/- √((2BL - U^2)^2 - 4B^2L^2) ] / 2L
Step-by-step explanation:
L = U^2A / (A + B)^2
U^2 A = L(A^2 + 2AB + B^2)
U^2 A = LA^2 + 2ABL + B^2L
LA^2 + 2ABL - U^2A + B^2 L = 0
LA^2 + (2BL - U^2)A + B^2L = 0
Using the quadratic formula
A = [- (2BL - U^2) +/- √[(2BL - U^2)^2 - 4*L*B^2L] / 2L
A = [- 2BL + U^2 +/- √[(2BL - U^2)^2 - 4B^2L^2) ] / 2L
