Adding 49 will explain it properly just do that and you will get the answers
The faction is 3/4.
I got the answer by doing 24/32 = 0.75.
Then, I converted the decimal into a fraction. Which, is 3/4.
I hope this helps! :)
Answer:
It will last 18 days.
Step-by-step explanation:
18x^2 + 2x + y^2 = 1
<span>==> 18(x^2 + x/9) + y^2 = 1 </span>
<span>==> 18(x^2 + x/9 + 1/324) + y^2 = 1 + 1/18 </span>
<span>==> 18(x + 1/18)^2 + y^2 = 19/18 </span>
<span>==> (x + 1/18)^2/19 + (y - 0)^2/(19/18) = 1. </span>
<span>By comparing this to the standard form of an ellipse, the center is at (-1/18, 0). </span>
y ≤ x − 5
y ≥ −x − 4
This is a check and see type of problem.
if x=5
y ≤ 5 − 5 y≤ 0
y ≥ −5 − 4
y ≥-9
-9≤ y ≤ 0
-2 works so (5,-2) is a solution
if x= -5
y ≤ -5 − 5 y≤ -10
y ≥ 5 − 4
y ≥1
no solution
Choice B (5,-2)
