For this case we have that by definition, the equation in the form of slope-intersection is given by:
Where
Substituting the given point: and the cutoff point
we can find the slope,
We have:
Thus, the equation is given by:
Answer:
See attached image
Answer:
1. x = +/- 2 - 7
2. x = +/-
3. n = +/-
Step-by-step explanation:
1. Divide both sides by 2: (x + 7)^2 = 8
Square root both sides: x + 7 = +/- 2
Subtract 7 from both sides: x = +/- 2 - 7
2. Square root both sides: x - 3 =
Since there is a negative inside the radical, we need to have an imaginary number: . So,
Add 3 to both sides: x = +/-
3. Divide by -5 from both sides: (n - 2)^2 = -2
Square root both sides: n - 2 =
Again, we have to use i:
Add 2 to both sides: n = +/-
Hope this helps!
Answer:
1
Step-by-step explanation:
Using the definition
n =
where n! = n(n - 1)(n - 2) × 3 × 2 × 1
and 0! = 1
