Given equation is x²-3x = 4
⇛ x²-3x -4 = 0
⇛ x²+x-4x-4 = 0
⇛ x(x+1)-4(x+1) = 0
⇛ (x+1)(x-4) = 0
⇛ x+1 = 0 or x-4 = 0
⇛ x = -1 or x = 4

Given equation is x²+4x+4 = 0
⇛ x²+2x+2x+4 = 0
⇛ x(x+2)+2(x+2) = 0
⇛ (x+2)(x+2) = 0
⇛ x+2 = 0
⇛ x = -2

Step-by-step explanation:
Answer: Choice C) 1/4
===================================================
Work Shown:
Let's rearrange terms a bit to say the following:
The last equation is in the form
where,
- |A| = amplitude
- B handles the period. Specifically T = 2pi/B, where T is the period
- C handles the phase shift, aka horizontal shifting
- D determines the midline and the vertical shifting
We only need to worry about the value of B.
In this case, B = 1/4
So,
The period is 8pi. Every 8pi units, a full cycle is completed.
However, we're not going from 0 to 8pi, but instead from 0 to 2pi.
The given interval is 2pi units wide. This is (2pi)/(8pi) = 1/4 of a full cycle. This is why choice C is the answer.
Answer:
14/13
Step-by-step explanation:
19/13-5/13=14/13
Since the denominators are the same, you just do the subtraction of the nominators.
