x = 0 and x = 4
To find intersection equate them.
x² - 2x - 4 = 2x - 4
subtract 2x - 4 from both sides
x² - 4x = 0 → (take out common factor x)
x(x - 4 ) = 0 ⇒ x = 0 , x = 4

This bar graph shows the number of hurricane in the Atlantic Basin from 2006-2011. Find the amount of change and the percent of decrease in the number of hurricanes from 2008 to 2009 and from 2010 to 2011. Compare the amount of change and percents of decrease.
Answer:
Step-by-step explanation:
Number of hurricanes in year 2008 = 8
Number of hurricanes in year 2009 = 3
Decrease in number of hurricanes = 8 - 3 = 5
Percent of decrease in number of hurricanes = [tex]\frac{5}{8}\times 100[/tex] = 62.5%
Number of hurricanes in year 2010 = 12
Number of hurricanes in year 2011 = 7
Decrease in number of hurricanes = 12 - 7 = 5
Percentage decrease in number of hurricanes = [tex]\frac{5}{12}\times 100[/tex] = 41.7%
Decrease in numbers of hurricanes in year 2010 - 11 was same as in year 2010 - 11.
Percentage decrease in hurricanes were more in year 2008 - 09 than percentage decrease in year 2010 - 11.

Answer:
The missing value in the table would be 160.
Step-by-step explanation:
The answer is 160 because each value on the left side of the table is multiplied by 8 to get the value on the right half, so we can assume that we need to multiply 20 by 8 to get the missing value on the right.
Answer:
160
Step-by-step explanation:
Note
2 × 8 = 16
4 × 8 = 32
60 × 8 = 480
Thus
20 × 8 = 160 ← missing value

The graph shows the calling charges of two cell phone companies. At how many minutes do the two companies charge the same amount?
Α. Ο
B. 15
C. 20
D 4
Answer: The answer would be C
Step-by-step explanation:
The two lines intersect on (20, 6) so that means that the charging rates were the same when on that point. And since it is asking for how many minutes they charge at the same amount, that would make it 20.

9x - 1 = -11. Simplify.
Hi there!
[tex]\large\boxed{x = \frac{-10}{9}}[/tex]
9x - 1 = -11
Add 1 to both sides:
9x -1 + 1 = -11 + 1
9x = -10
Divide both sides by 9:
9x/9 = -10/9
x = -10/9

How many 1/3 inch cubes does it take to fill a box with width 2 2/3 inches, length 3 1/3 inches, and height 2 1/3 inches?
Answer:
560/9 cubes
Step-by-step explanation:
How many 1/3 inch cubes does it take to fill a box
the dimension of the box is
width 2 2/3 inches,
length 3 1/3 inches, and
height 2 1/3 inches
The volume of the box is
volume= L*W*H
volume= 3 1/3 * 2 2/3* 2 1/3
converting to proper fraction
volume= 10/3*8/3*7/3
volume= 10*8*7/3*3*3
volume=560/27 in^3
the volume of the cube is 1/3
so the number of cubes will be
=560/27/1/3
=560/27*3
=560/9

HELP!! What is the length of AB
Answer:
ITS B
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
triangle ABC is an isosceles triangle since there are two equal angles
hence,
AB = BC
4x = 2x + 6
4x - 2x - 6 = 0
2x - 6 = 0
2x = 6
x = 3
AB = 4x
AB = 4 * 3
AB = 12

What is the value of y?
O 2/3 units
O 4 units
O 4/3 units
O 8 units
Answer:
y = 4[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using the altitude- on- hypotenuse theorem
( leg of large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )
y² = 6 × (6 + 2) = 6 × 8 = 48 ( take the square root of both sides )
y = [tex]\sqrt{48}[/tex]
= [tex]\sqrt{16(3)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{3}[/tex] = 4[tex]\sqrt{3}[/tex]
Answer: 4/3
Step-by-step explanation:
Two vertical angles have measures of (4x + 8) and (7x -22). What is the measure of the two angles?
Answer:
48
Step-by-step explanation:
Vertical angles are congruent
7x - 22 = 4x + 8 {Add 22 to both sides}
7x = 4x + 8 + 22
7x = 4x + 30 { subtract 4x from both sides}
7x - 4x = 30
3x = 30
x = 30/3
x = 10
4x + 8 = 4*10 + 8
= 40 + 8
= 48
7x - 22 = 7*10 - 22
= 70 - 22
= 48
