+2.15.
Explanation: subtract 6.3 by 4.15 = 2.15 so you add 2.15
Answer:
x=29
Step-by-step explanation:
The square notation indicates 90 degrees.
90=(x+3)+(x-1)+(x+1)
90=3x+3
87=3x
x=29
Answer:
450
Step-by-step explanation:
here is a fast way:
1- 75% = 75/100 = 3/4
2- 600 × (3/4) = 450
Y determines how many hours, and x gives you the whole amount.

The behavior of the function around its vertical asymptote at 

Expand the numerator

Factorize

Factor out x + 1

We test the function using values close to -2 (one value will be less than -2 while the other will be greater than -2)
We are only interested in the sign of the result
----------------------------------------------------------------------------------------------------------
As x approaches -2 implies that:
Say x = -3


We have a negative value (-12); This will be called negative infinity
This implies that as x approaches -2, p(x) approaches negative infinity

Take note of the superscript of 2 (this implies that, we approach 2 from a value less than 2)
As x leaves -2 implies that: 
Say x = -2.1

We have a negative value (-56.1); This will be called negative infinity
This implies that as x leaves -2, p(x) approaches negative infinity

So, the behavior is:
and as
