Just substitute 3 for x, and it’s 3+1=4. Your answer is 4!
Answer:
x = -5, x = -6
Step-by-step explanation:
After canceling common terms from numerator and denominator, there are two factors remaining in the denominator that can become zero. The vertical asymptotes are at those values of x.

The denominator will be zero when ...
x + 5 = 0 . . . . at x = -5
x + 6 = 0 . . . . at x = -6
Answer:
25
Step-by-step explanation:
Given that:
Initial payment done for buying the phone = $50
Charges per month for the phone = $25 per month
To find:
The equation to represent the situation and its slope.
Solution:
First of all, let us assume that
represents the number of months for which monthly is to be made.
Charges paid for one month = $25
Charges paid for
months = $25
Total cost of the phone = Initial payment + Charges paid for
months

It is a linear equation between two variables
and
.
This equation can be compared with slope intercept form of a line.
Slope intercept form of a line is represented by:

is the slope.
On Comparing, we get:

Therefore, the slope is <em>25</em>.

Answer: The answer is 6.
The number sentence is
3-3=0
10-4=6
So, 13-7=6
Step-by-step explanation:
To solve
, by making ten
First break 13 and write 
Then break 7 as 
Now to subtract 7 from 13,
Step 1. Subtract 3 (a part of 7), from 3(a part of 13) or cross 3 circles, then we have left 10-4

Step 2. Subtract 4 from 10 or cross 4 circles out of 10, we get 6.
The answer is 6.
