STEP
1
:
5a + 5b
Simplify ———————
a2 - b2
STEP
2
:
Pulling out like terms
2.1 Pull out like factors :
5a + 5b = 5 • (a + b)
Trying to factor as a Difference of Squares:
2.2 Factoring: a2 - 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 : a2 is the square of a1
Check : b2 is the square of b1
Factorization is : (a + b) • (a - b)
Canceling Out :
2.3 Cancel out (a + b) which appears on both sides of the fraction line.
Final result :
5 / a -b
Step-by-step explanation:
The linear equation in its generic form is:
y-yo = m (x-xo)
In this case we have that the slope is:
m = 300
The ordered pair is:
(xo, yo) = (2, 1400)
Substituting we have:
y-1400 = -300 (x-2)
Rewriting:
y = -300x + 600 + 1400
y = -300x + 2000
Answer:
a linear function that models this scenario is:
y = -300x + 2000
The slope of the line is:
-300
The y-intercept of the line is:
2000
Thank you for the question the answer is X=f - 7 over 4
