Answer:
B. Y= x^2+4x+6
Step-by-step explanation:
You plug in the numbers into the quadratic formula.
a=1 b=4 c=6
Answer:
The answer is (b)
Step-by-step explanation:
The quadratic formula is (-b±√(b^2-4ac))/2a. Letter choice (b) is x^2 + 4x +6. Since there is no number before x, we can assume it is 1. With this, you just plug the numbers into the letters. a=1, b=4, and c=6. When you do this, you get (-4±√(16-4(1)(6))/2(1). The 16 comes from 4^2. Hope this helps.

If the spinner shown is spun 40 times, predict the number of times the spinner would land on Section B.
Answers
Answer:
10 times
Step-by-step explanation:
Given that:
Number of sections = (A, B, C, D) = 4
Probability of spinner landing on section B on a single spin = required outcome / Total possible outcomes
P(landing on B) = 1 /4
Predicted Number of times spinner will land on D ; if spinner is spurned 40 times
1/4 * 40 = 10 times

Step-by-step explanation:
Given
See attachment for plot
Required
Determine the probability that few than 7 boxes will be needed.
This is represented as:
[tex]P(x < 7)[/tex]
And the solution is:
[tex]P(x < 7) = P(x = 4) + P(x = 5) + P(x = 6)[/tex]
Each probability is calculated by dividing the number of dots by the total dots.
So, we have:
[tex]P(x < 7) = \frac{n(x = 4) + n(x = 5) + n(x = 6)}{Total}[/tex]
From the attached, the formula becomes:
[tex]P(x < 7) = \frac{4 + 6 + 3}{4+6+3+4+4+6+3+2+1+2+0+1}[/tex]
[tex]P(x < 7) = \frac{13}{36}[/tex]

The distance between is the number of units between them, and the distance from Diego's ship to the closest island is 5.4 units
What is a point coordinate?A point coordinate is the location of a point on the coordinate plane
From the question, the coordinate of point X is:
X = (-2, -4)
The closest island to point X is the island B, and the coordinate is:
B = (3, -6)
The distance is then calculated using:
XB =√[(x₁ - x₂)² + (y₁ - y₂)²]
So, we have:
XB =√[(-2 - 3)² + (-4 + 6)²]
Evaluate
XB = 5.4
Hence, the distance from Diego's ship to the closest island is 5.4 units

Answer:
x = 23 degrees
Step-by-step explanation:
It is given that the two parallel lines, (m) and (n) are intersected by a transversal. The two given angles (5x - 20) and (85) are alternate corresponding. Meaning that they are supplementary; their angle measures add up to (180) degrees. Based on this given information, form an equation and solve for the parameter (x).
(5x - 20) + (85) = 180

-4/7 > - 2
On a number line, numbers are arranged in ascending order (lowest to smallest) the number at the tail end to the left of the numbwr line will be the least number represented by the number line and the highest will be located at the end of the right side of the number line.
Therefore, if it is represented that -4/7 > - 2
Then counting from the left ; - 2 comes before - 4/7
Hence, - 4/7 is located to the right of −2

Answers
Answer:
Step-by-step explanation:
(-1,4) (1,4) 2,0
The endpoint of the line segment will be (-1, 4) and (2, 0). Then the correct options are B and E.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
A line segment in mathematics has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a path that joins two places.
Section Stomach muscle has endpoints A(- 2, 8) and B(4,0). The section is widened at the beginning by a scale variable of 0.5 to make a fragment of the Stomach muscle.
The endpoint of the line segment is given as,
A = 0.5(-2, 8)
A = (-1, 4)
B = 0.5(4, 0)
B = (2, 0)
The endpoint of the line fragment will be (- 1, 4) and (2, 0). Then the right choices are B and E.

The sum of the ages of Farhan and his cousin is 38. Seven years ago, Farhan
was thrice as old as his cousin.Find Farhan's present age.
Answers
Answer:
25 and 13
Step-by-step explanation:
sum of ages of Farhan and his cousin = 38
7 years ago Farhan thrice of his cousin = 3:1
7 year ago the sum of their ages = 38-14 = 24( 7 years for each)
3:1 = 4 units = 24
1 unit =6
ages of Farhan and his cousin 7 years ago = 6*3= 18 and 6*1 = 6
so the present age of Farhan = 18+7 = 25 and his cousin 6+7 = 13

Answer:
[1] x - 4y = 22

Step-by-step explanation:
Solve equation [1] for the variable x
[1] x = 4y + 22
// Plug this in for variable x in equation [2]
[2] 2•(4y+22) + 5y = -21
[2] 13y = -65
// Solve equation [2] for the variable y
[2] 13y = - 65
[2] y = - 5
// By now we know this much :
x = 4y+22
y = -5
// Use the y value to solve for x
x = 4(-5)+22 = 2
