Answer:
The point slope form of this equation would be y - 0 = -2(x + 1)
Step-by-step explanation:
In order to find this, we start by identifying that the x-intercept at -1 is the point (-1, 0). Now we can use that full point and the slope and plug them into the base form of point-slope form.
y - y1 = m(x - x1)
y - 0 = -2(x - -1)
y - 0 = -2(x + 1)
We add 7 to both sides, making x=31. we can substitute 31 and make the true number sentence.
only 31 can be substituted, as it is only one x value, holding only one true value, which we found out is 31.
hope this helped!! xx

Answer:
3/(x +1) -4/(x +1)^2
Step-by-step explanation:
The partial fraction expansion will be of the form ...
A/(x+1)^2 +B/(x+1)
We can find the values of A and B by writing the sum of these terms:
= (A +B(x +1))/(x +1)^2
Then we require ...
B = 3
A +B = -1 ⇒ A = -4
So, the desired expansion is ...
3/(x +1) -4/(x +1)^2
Answer:
A
