Answer:
w = -1/2
Step-by-step explanation:
Eliminate parentheses, collect terms:
7w +14 = -12w +6 +3w . . . eliminate parentheses
7w +14 = -9w +6 . . . . . . . . collect terms
16w +14 = 6 . . . . . . . . . . . . add 9w
16w = -8 . . . . . . . . . . . . . . . subtract 14
w = -1/2 . . . . . . . divide by 16, reduce the fraction

<em>Check</em>
7(-1/2 +2) = -6(2(-1/2) -1) +3(-1/2)
7(3/2) = -6(-2) -3/2
21/2 = 12 -3/2 . . . . . true, answer checks OK
Answer: First building at 17.5 months
Step-by-step explanation:
Months you can stay in the first building.
One time fee of $1,000 reduces the amount you have to;
= 15,000 - 1,000
= $14,000
Rent is $800. Months you can stay;
= 14,000/800
= 17.5 months
Months you can stay in second building;
Rent is $1,000 and no one time fee;
= 15,000/1,000
= 15 months
<em>You can stay longer in the first building for 17.5 months. </em>

Answer: koh-rien
Step-by-step explanation:
Answer:
first option
Step-by-step explanation:
Given
f(x) = 
← factorise the numerator
= 
← cancel (x + 4) on numerator/ denominator
= 2x - 3
Cancelling (x + 4) creates a discontinuity ( a hole ) at x + 4 = 0, that is
x = - 4
Substitute x = - 4 into the simplified f(x) for y- coordinate
f(- 4) = 2(- 4) - 3 = - 8 - 3 = - 11
The discontinuity occurs at (- 4, - 11 )
To obtain the zero let f(x) = 0, that is
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = 
There is a zero at ( , 0 )
Thus
discontinuity at (- 4, - 11 ), zero at ( , 0 )
