factor 4a^2-b^2-2a+b
Answer:Equation at the end of step 1
STEP
2
:
4a2 - b2
Simplify ————————
2a - b
Trying to factor as a Difference of Squares:
2.1 Factoring: 4a2 - b2
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 4 is the square of 2
Check : a2 is the square of a1
Check : b2 is the square of b1
Factorization is : (2a + b) • (2a - b)
Canceling Out :
2.2 Cancel out (2a - b) which appears on both sides of the fraction line.
Final result :
2a + b

Answer pls
Answer: x = 8
Step-by-step explanation:
Answer:
x=8
Step-by-step explanation:
10= -1/4x+12
move the 12 to the other side
10-12= -1/4x
-2= -1/4x
divide -1/4 by both sides
8=x

Answer:
subtract 2.4 from both sides, simplify to -3x=16.8, divide by -3, simplify to x=-5.6.
Step-by-step explanation:
-3x + 2.4 = 19.2
v -2.4 -2.4
v 0 16.8
-3x=16.8

Step-by-step explanation:
r + 4s = -8
3r + 2s = 6
Answer:
R = 4
s = -3
Step-by-step explanation:
r + 4s = -8
3r + 2s = 6
there are several ways to solve this system but i chose the elimination method and multiplied the second equation by -2 to get:
-6r - 4s = -12 and added it to the first equation
+ 1r + 4s = -8
-5r = -20
r = 4
plug in to find 's': 4 + 4s = -8
4s = -12
s = -3
What is the distance between (2, 5) and (2,-5) on the coordinate plane
Answer:
10
Step-by-step explanation:
When you find the distance, you just add both of the numbers as if they were in absolute value 5+|-5|
so then since the x values are the same, you would go up/down 10 spaces on the Y-axis
Answer:
10 units
Step-by-step explanation:
Use the distance formula:
[tex]\sqrt{ (x_{2} - x_{1} )^2 -(y_{2} - y_{1} )^2[/tex]
Plug in values:
[tex]\sqrt{ (-5-5 )^2 -(2-2 )^2[/tex]
[tex]\sqrt 100[/tex]

A school district currently has 12,000 students. Based on declining enrollment figures, the number of students in the school district is expected to decline by 5% each year. Which of the following functions represents the number of students, S, in the school district after n years?
Answer:
S(n) = 12,000(–0.05)n
Step-by-step explanation:
The function that represents the number of students, S, in the school district after n years is [tex]S=12000(0.95)^n[/tex]
Original population , P = 12000
Rate of decline, r = 5%
r = 5/100
r = 0.05
The number of years = n
The population of students after n years will be given by the formula:
[tex]S =P(1-r)^n[/tex]
Substitute r = 0.05 and P = 12000 into the formula above
[tex]S=12000(1-0.05)^n\\\\S=12000(0.95)^n[/tex]
The function that represents the number of students, S, in the school district after n years is [tex]S=12000(0.95)^n[/tex]
