Y=(x+1)(x-1) this is factored out
Answer:
x = -3
Step-by-step explanation:
55 + x + 74 + 54 = 180
x + 183 = 180
x = -3
Because percentage is the numerator divided by the denominator of a fraction times one-hundred, we can set up this equation:

Now, we cross multiply.

Next, we divide both sides by 0.55 to get x by itself.
x = 60
So, 33 is 55% of 60.
If the 2 lines are parallel, their slopes are the same.
The slope of both is
3+3
m = ---------- = 3
2 - 0
If the new line <span>passes through the point (−1, −1), then the equation in point slope form is:
y+1 = 3(x+1).</span>
21.325 is the correct answer
