For this case, what you should see is which lines contain point O.
We have then that the lines that contain this point are:
EC
AD
BO
We note that three lines contain point O.
Therefore, three lines intersect at the same point.
Answer:
4. 3
To make twice you spend on arcade, you will need to make:
$85,489 x 2 = $<span>170 978
</span>
You make <span>$10,153 a week
Number of weeks needed = </span>$170 978 ÷ $10,153
Number of weeks needed = 16.84 ≈ 17 weeks
You will need 17 weeks to make twice as much as you spent in arcade.
Answer:
the 1st option is false; there is no 'addition' sign
Step-by-step explanation:

I'm not sure what methods you've learned up to this point but one option is to apply separation of variables:

and then integrate from there,

exponentiate to isolate y,

Apply exponent rule,

rename this e^c as some new constant, perhaps A,

This A can only be positive, non-zero, but absorbing the plus/minus fixes that restriction,

Use your initial information to solve for this unknown value A,

solving for A, dividing by the exponential,

So we get a final result of

apply exponent rule again to get a better looking answer, and factor,

Lemme know if too confusing.
