AD is the perpendicular bisector of BC.
BD = 5x – 10 and DC = 3x + 10.
Determine the value of x.
5x-10= 3x+10
5x-3x= 10+10
2x÷2= 20÷2
x= 10
Step-by-step explanation:
as AD bisects them they will be two equal parts so
5x-10=3x+10
5x-3x=10+10
2x=20
divide both sides by 2 and
x=10

1. what is the doamin and range form this graph and the minimum and maximum and interval of increase and decrease?
Answer:
Below.
Step-by-step explanation:
The Domain is all real values of x.
The range is -6 ≤ f(x) < ∞.
( I cant see the minimum value very clearly but I think its -6).
Minimum -6 Maxm ∞.
Decreasing from f(x) = -∞ to f(x) = -6.
Increasing from f(x) = -6 to ∞.

Which of the following are solutions to the equation below? Check all that apply. 4x2 - 12x + 9 = 5
Step-by-step explanation:
4x² - 12x + 9 = 5 → 4x² - 12x + 4 = 0 → x² - 3x + 1 = 0
∆ = b² - 4ac → ∆ = (-3)² -4(1)(1) = 9 - 4 = 5
x = (-(-3) ± √5)/2(1) = (3 ± √5)/2
x² - 3x + 1 = 0 → (x - 3/2)² - 9/4 + 1 = 0 → (x - 3/2)² = 5/4 → x - 3/2 = ±√5 / 2 → x = ½( 3 ± √5)

A towns population went from 40,000 to 50,000. What was the percent of change in the population?
Answer:
The percent of change in the population was of 25%.
Step-by-step explanation:
Percent change:
The percent change is given by the change multiplied by 100, and divided by the initial value.
A towns population went from 40,000 to 50,000.
Change: 50000 - 40000 = 10000
Initial value: 40000
10000*100/40000 = 25%
The percent of change in the population was of 25%.

Sheila is moving to a new house. She rents a truck with a storage body as shown below.
All of her belongings are in boxes that each have a volume of 9 cubic feet.
How many boxes can she fit in the storage body?
Use the drop-down menus to show your solution.
Cuboid with length as 15 ft, height as 8 ft and width as 6 ft. is given. Another cuboid with length of 4 ft, height of 6 ft and width as 6 ft is cut from bottom left corner of the bigger cuboid.
The volume of the storage body is
cubic feet.
To find how many boxes Sheila can fit in the storage body, by .
Sheila can fit
boxes into the truck.
Answer:
See below
Step-by-step explanation:
Since the shape of the truck isn't given and the volume, we will make some assumptions. You can solve this problem if you have the complete one by following the same procedure. Lets assume:
Shape of Truck is Cuboid
The dimensions of the Truck is 9 by 9 by 9
First, we need to find the volume of the cuboid truck.
Volume is basically 3 dimensions multiplied together. So that would be:
Volume of Truck = 9 * 9 * 9 = 729 cubic feet
Each box has a volume of 9 cubic feet. To get number of boxes that evenly fit the truck, we would need to divide the truck's volume by volume of each box.
729/9 = 81 boxes

Nuts berry farm makes their own trail mix using nuts and berries. Each pack of trail mix has a 3 tablespoon of nuts and 1 tablespoon of berries. Enter the percentage of the trail mix that is berries
Answer:
25%
Step-by-step explanation:
There's 3 tablespoons of nuts and 1 tablespoon of berries, so 1/4 tablespoons is berries.
Answer:
To sum up, we looked at the important amount devided by the total amount. Finally we solved for p. Which gave us p=75. Furthermore 75 percent of the trail mix is made up out of berries.
Step-by-step explanation:
So the main equation with percentages is W/G = p/100.
So First we look at G. G describes the total amount. In this case the total amount of teaspoons is four. Four because we have three tablespoons of berries and one tablespoon of nuts. That is four tablespoons.
Now we can go further to find out what W is. 2 is the important amount. In the question we are supposed to look at the amount of berries is the trail mix. Which gives us the value three.
So far our equation has no unknowns anymore 3/4=p/100. We multiply both sides of the equation with 100 3*100/4=p. Thus p = 300/4=150/2=75.

What are the solutions to the quadric equation x^2-16=0
Answer:
x=4, x=-4
Step-by-step explanation:
x^2-16=0
Add 16 to both sides;
x^2-16+16=0+16
Simplify;
x^2=16
x=[tex]\sqrt{16}[/tex], x[tex]-\sqrt{16}[/tex]
[tex]\sqrt{16}[/tex]
=4
factor the number;16
[tex]\sqrt{4^2}[/tex]
=[tex]\sqrt{4}[/tex]
-[tex]\sqrt{16}[/tex]
Factor the number 16;
[tex]\sqrt{4^2}[/tex]
=-4
You may recall that the area of a rectangle is A=L⋅W, where W is the width and L is the length.
Suppose that the length of a rectangle is 2 times the width. If the area is 128 square feet, then what is the width of the rectangle, in feet?
Answer:
length=2×width
2width×width=128
2width ²/2. =128/2
width². =64
width=8feet
