(A) Find the midpoint of the segment
(B) Find the length of the segment
Answer:
The midpoint is (1, 3) and the length of the segment (let's call it AB) is 6.32
Step-by-step explanation:
Answer:
A) (1, 3)
B) [tex]2\sqrt{10}\\[/tex]
Step-by-step explanation:
A) We are finding the averages of the x and y values. The midpoint formula is as so:
(x1 + x2/2, y1 + y2/2)
(-2+4/2 , 4+2/2)
(2/2 , 6/2)
(1.3)
With distance, the formula is[tex]\sqrt{(x_{1} -x_{2})^{2} + (y_{1} -y_{2})^{2}[/tex]
[tex]\sqrt{(4-(-2))^{2} + (2-4)^{2}[/tex]
[tex]\sqrt{(6)^{2} + (-2)^{2}[/tex]

x2+7x+12=0 please help
Answer:
x has the values -4 and -3
Step-by-step explanation:
x² + 7x + 12 = 0
x² + 3x + 4x + 12 = 0
x(x + 3) + 4(x + 3) = 0
(x + 4)(x + 3) = 0
What’s the solution for y=2x+7 y=3x-1
Answer:
x=8 and y=23
Step-by-step explanation:
Rewrite equations:
y=2x+7;y=3x−1
Step: Solve y=2x+7 for y:
y=2x+7
Step: Substitute 2x+7 for y in y=3x−1:
y=3x−1
2x+7=3x−1
2x+7+−3x=3x−1+−3x(Add -3x to both sides)
−x+7=−1
−x+7+−7=−1+−7(Add -7 to both sides)
−x=−8−x−1=−8−1
(Divide both sides by -1)
x=8
Step: Substitute 8 for x in y=2x+7:
y=2x+7
y=(2)(8)+7
y=23(Simplify both sides of the equation)

Solve for x in the diagram below.
3xº
75°
Answer:
x = 35°
Step-by-step explanation:
A flat line = 180°
Knowing that, we can make an equation:
3x + 75 = 180
Now, solve:
3x + 75 = 180
- 75 - 75
3x = 105
x = 35
Hope this helps :)
Answer:x=35
Step-by-step explanation:180-75=105
105/3=35

The admission ticket for Pat Pat Zoo is $1.50 for children and $4.00 for adults. On a certain day, 2200 people went to the zoo and $5050 was collected. How many children and how many adults went to the zoo that day?
Answer:
1380 children and 820 adults went to the zoo that day
Step-by-step explanation:
System of Equations
Define the following variables
x = number of children that went to the zoo
y = number of adults that went to the zoo
On a certain day, 2000 people went to the zoo, thus:
x + y = 2000
Solving for x:
x = 2000 - y [1]
The admission ticket is $1.50 for children and $4.00 for adults and that same day, $5050 was collected, then:
1.50x + 4y = 5050 [2]
Substituting x from [1]:
1.50(2000 - y) + 4y = 5050
Operating:
3000 - 1.50y + 4y = 5050
3000 + 2.5y = 5050
Subtracting 3000
2.5y = 5050 - 3000 = 2050
Dividing by 2.5
y = 820
From [1]
x = 2200 - 820 = 1380
1380 children and 820 adults went to the zoo that day
