The midpoint of the line segment is (-1, -1).
What is midpoint of a line segment?The midpoint of a line segment is a point that lies halfway between 2 points. The midpoint is the same distance from each endpoint.
It is obtained by averaging the x-coordinates and averaging the y-coordinates of the endpoints of the segment.
Given endpoints
A(− 4, −5) and B(2, 3)
Midpoint of the line segment formula:
Midpoint of a Line Segment : Its x value is halfway between the two x values · Its y value is halfway between the two y values.
Midpoint [tex]= (\frac{x_{1}+x_{2} }{2} ,\frac{y_{1}+y_{2} }{2})[/tex]
Midpoint = [tex](\frac{-4+2}{2} ,\frac{-5+3}{2} )[/tex]
Midpoint = [tex](\frac{-2}{2}, \frac{-2}{2} )[/tex]
Midpoint = (-1, -1)
The midpoint of the line segment is (-1, -1).

Well..They gave you the hint all you have to do is apply the formula
hint: the way a quadratic formula is written is [tex]ax^2 + bx + c[/tex]
So lets do this
axis of symmetry = [tex]\frac{-b}{2a} = \frac{-(-12)}{2(-3)} = \frac{12}{-6} = -2 = x[/tex]

find the value of x in the picture
Answer:
x = 9
Step-by-step explanation:
5x+4 = 49
subtract 4 from both sides
5x = 45
divide both sides by 5
x = 9
Answer:
x = 9
Step-by-step explanation:
49 degrees and (5x + 4) are vertical lines, meaning they are congruent.
We can make an equation with this information:
(5x + 4) = 49
-4 -4
5x = 45
/5 /5
x = 9

Answer:
[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]
Step-by-step explanation:
Given
[tex]S = \{1,2,3,4,5\}[/tex]
[tex]n(S) = 5[/tex]
Required
[tex]P(x > 1\ and\ x < 2)[/tex]
[tex]P(x > 1\ and\ x < 2)[/tex] is calculated as:
[tex]P(x > 1\ and\ x < 2) = P(x > 1) * P(x < 2)[/tex]
Since it is a probability with replacement, we have:
[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]
For x > 1, we have:
[tex]x > 1 = \{2,3,4,5\}\\[/tex]
[tex]n(x > 1) = 4[/tex]
For x < 2, we have:
[tex]x < 2 = \{1\}[/tex]
[tex]n(x < 2) = 1[/tex]
[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]
becomes
[tex]P(x > 1\ and\ x < 2) = \frac{4}{5} * \frac{1}{5}[/tex]
[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]
According to the stem-and-leaf plot above, how many drivers travel below 80 miles hour per hour? A. 2 B. 6 C. 14 D. 5
Answer:
See Explanation
Step-by-step explanation:
Given
The question is incomplete, as the required stem-and-leaf plot is not available. I will answer this question with the attached plot
Required
Drivers that travel below 80 mph
A stem and leaf plot has the following syntax: Stem | Leaves
Take for instance:
7 | 2 3 4 7
The above represents 72, 73, 74 and 77
Using the above illustration, the attached leaf plot can be interpreted as:
60, 61, 61, 65, 66, 66, 67
71, 73, 76, 77, 78
80 81... and so on
The drivers that drive below 80 mph are:
60, 61, 61, 65, 66, 66, 67
71, 73, 76, 77, 78
And the frequency is: 12
Hence, 12 drivers travel below 80 mph (using the attached stem and leaf plot)

The value of a car with an initial purchase price of $12,250 depreciates by 11 percent per year
Answer:
It is decay because the value of the car keeps falling.
for example, the value next year, would be 12250 x (100% - 11%) = $10,902.50
If it were a growth, the value would increase yearly
12250 x (0.89)^time
Step-by-step explanation:
the equation to represent exponential decay = Amount x ( 1 - rate)^time
