Answer:
AB = 54
Step-by-step explanation:
DE is a midsegment of the triangle and is half of AB , that is
2x + 13 = [tex]\frac{1}{2}[/tex](13x - 37) ← multiply through by 2 to clear the fraction
4x + 26 = 13x - 37 ( subtract 13x from both sides )
- 9x + 26 = - 37 ( subtract 26 from both sides )
- 9x = - 63 ( divide both sides by - 9 )
x = 7
Thus
AB = 13x - 37 = 13(7) - 37 = 91 - 37 = 54

3,1,-2,-4,-1, least to greatest
Answer:
-4, -2, -1, 1, 3
Step-by-step explanation:
Because some of these numbers are negative, they will be getting smaller as they get bigger. Think of it like this:
When you are determining whether the negative number is bigger or smaller, take the negative sign off or pretend its not there. Then, as the numbers get bigger, they become less. For example, you have these numbers:
-1, -5, -8, -3, and -2
To find out what the order is from least to greatest, you do this:
take the negative sign off
1,5,8,3, and 2
then put them in order from least to greatest
so its
1, 2, 3, 5, 8
Then flip it so its from greatest to least
so its
8,5,3,2,1
Now put the negative signs back
making it:
-8, -5, -3, -2, and -1
That is how you find out what the numbers are from least to greatest.
Hope this helps!

Answer:
The slope of the line = m = 3
Step-by-step explanation:
Given the table
x 3 6 8 12
y 7 16 22 34
Taking any two points let say (3, 7) and (6, 16)
(x₁, y₁) = (3, 7) (x₂, y₂) = (6, 16)Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [16 - 7] / [6 - 3]
= 9 / 3
= 3
Therefore, the slope of the line = m = 3

Kathy jumped 16 1/2 ft at the long jump event. Nadia jumped 18 1/8 ft at the long jump. How much farther did Nadia jump than Kathy?
Answer:
12 ft
Step-by-step explanation:
First you do 16 x 2 +1 and you get 133, second you do 18 x 8 +1 = 145 third you need to subtract 145 - 133, and you get 12 feet.

1. g(x) = -2(x + 3) 2 - 1
Identify the a,h,k and vertex for each quadratic function
9514 1404 393
Answer:
a = -2, h = -3, k = -1
vertex = (-3, -1)
Step-by-step explanation:
Compare the given equation ...
g(x) = -2(x +3)² -1
to the vertex form ...
g(x) = a(x -h)² +k
You see that ...
a = -2
-h = +3 ⇒ h = -3
+k = -1 ⇒ k = -1
The vertex is (h, k), so is ...
vertex = (-3, -1)

Answer:
Step-by-step explanation:
The formula for the gravitational potential energy of an object is U = mgh, where U represents the potential energy, m represents the mass of the object, g represents the acceleration due to gravity, and h represents the object’s height above the ground. Solve this formula for h.
U=mgh
U/m=gh
U/mg=h
therefore:
h=U/mg
The solution for h is h = U / (mg),
where U represents the potential energy, m represents the mass of the object, and g represents the acceleration due to gravity.
Here, we have,
To solve the formula U = mgh for h (the height above the ground),
we need to isolate h on one side of the equation.
Here are the steps:
Start by dividing both sides of the equation by mg:
U / (mg) = (mgh) / (mg)
This simplifies to:
U / (mg) = h
Now we have isolated h on one side of the equation.
Therefore, the formula for h is:
h = U / (mg)
So, the solution for h is h = U / (mg),
where U represents the potential energy, m represents the mass of the object, and g represents the acceleration due to gravity.

In the diagram below AB is parallel to CD what is the value of x
The value of x is 150°. The correct option is D. 150°
Calculating anglesFrom the question, we are to determine the measure of angle x
In the given diagram, we can observe that
The angle supplementary with x is 30° (Alternate angles theorem)
Thus,
x + 30° = 180° (Supplementary angles)
x = 180° - 30°
x = 150°
Hence, the value of x is 150°. The correct option is D. 150°
