Vertical line (when y = 0)
⇒ Equation : x = -1
Horizontal line (when x = 0)
⇒ Equation : y = -8
--------------------------------------------------------------
Answer: x = -1, y = -8

Let x be the original cost for the sofa.
X x (1 + 0.07) =3210
X = 3000
Now we know the cost for the sofa.
Let p be the profit percent.
3000 x (1 + p) = 3360
P = 0.12
So the percentage profit is 12%
Answer:
the answer is 1/12 I did this in algebra not long ago
Answer:
The last option
Step-by-step explanation:

<u>Let us assume that:</u>

We can also write it as:

Squaring both sides, we get:


By splitting the middle term:



<u>Therefore:</u>


<u>But x cannot be negative. </u>

Therefore, the value of the expression is 3.

Given:

We can also write it as:






This pattern will continue.
